Sync contrib/tools/python3 layout with upstream

* Move src/ subdir contents to the top of the layout
* Rename self-written lib -> lib2 to avoid CaseFolding warning from the VCS
* Regenerate contrib/libs/python proxy-headers accordingly

+
+        stream->next_out:  point to the next output position.
+        stream->avail_out: the number of available bytes left in the buffer.
+
+   It maintains a list of bytes object, so there is no overhead of resizing

+
+   Usage:
+
+   1, Initialize the struct instance like this:
+        _BlocksOutputBuffer buffer = {.list = NULL};
+      Set .list to NULL for _BlocksOutputBuffer_OnError()
+
+   2, Initialize the buffer use one of these functions:
+        _BlocksOutputBuffer_InitAndGrow()
+        _BlocksOutputBuffer_InitWithSize()
+
+   3, If (avail_out == 0), grow the buffer:
+        _BlocksOutputBuffer_Grow()
+
+   4, Get the current outputted data size:
+        _BlocksOutputBuffer_GetDataSize()
+
+   5, Finish the buffer, and return a bytes object:

+   NOTE: about untracking of mutable objects.
+
+   Certain types of container cannot participate in a reference cycle, and
+   so do not need to be tracked by the garbage collector. Untracking these
+   objects reduces the cost of garbage collections. However, determining
+   which objects may be untracked is not free, and the costs must be
+   weighed against the benefits for garbage collection.
+
+   There are two possible strategies for when to untrack a container:
+
+   i) When the container is created.
+   ii) When the container is examined by the garbage collector.
+
+   Tuples containing only immutable objects (integers, strings etc, and
+   recursively, tuples of immutable objects) do not need to be tracked.
+   The interpreter creates a large number of tuples, many of which will
+   not survive until garbage collection. It is therefore not worthwhile
+   to untrack eligible tuples at creation time.
+
+   Instead, all tuples except the empty tuple are tracked when created.
+   During garbage collection it is determined whether any surviving tuples
+   can be untracked. A tuple can be untracked if all of its contents are
+   already not tracked. Tuples are examined for untracking in all garbage
+   collection cycles. It may take more than one cycle to untrack a tuple.
+
+   Dictionaries containing only immutable objects also do not need to be
+   tracked. Dictionaries are untracked when created. If a tracked item is
+   inserted into a dictionary (either as a key or value), the dictionary
+   becomes tracked. During a full garbage collection (all generations),
+   the collector will untrack any dictionaries whose contents are not
+   tracked.
+
+   The module provides the python function is_tracked(obj), which returns
+   the CURRENT tracking status of the object. Subsequent garbage
+   collections may change the tracking status of the object.
+
+   Untracking of certain containers was introduced in issue #4688, and
+   the algorithm was refined in response to issue #14775.

+HAMT tree is shaped by hashes of keys. Every group of 5 bits of a hash denotes
+the exact position of the key in one level of the tree. Since we're using
+32 bit hashes, we can have at most 7 such levels. Although if there are

+ * Allocation strategy abstract:
+ *
+ * For small requests, the allocator sub-allocates <Big> blocks of memory.
+ * Requests greater than SMALL_REQUEST_THRESHOLD bytes are routed to the
+ * system's allocator.
+ *
+ * Small requests are grouped in size classes spaced 8 bytes apart, due
+ * to the required valid alignment of the returned address. Requests of
+ * a particular size are serviced from memory pools of 4K (one VMM page).
+ * Pools are fragmented on demand and contain free lists of blocks of one
+ * particular size class. In other words, there is a fixed-size allocator
+ * for each size class. Free pools are shared by the different allocators
+ * thus minimizing the space reserved for a particular size class.
+ *
+ * This allocation strategy is a variant of what is known as "simple
+ * segregated storage based on array of free lists". The main drawback of
+ * simple segregated storage is that we might end up with lot of reserved
+ * memory for the different free lists, which degenerate in time. To avoid
+ * this, we partition each free list in pools and we share dynamically the
+ * reserved space between all free lists. This technique is quite efficient
+ * for memory intensive programs which allocate mainly small-sized blocks.
+ *
+ * For small requests we have the following table:
+ *
+ * Request in bytes     Size of allocated block      Size class idx
+ * ----------------------------------------------------------------
+ *        1-8                     8                       0

+ * Pool table -- headed, circular, doubly-linked lists of partially used pools.
+
+This is involved.  For an index i, usedpools[i+i] is the header for a list of
+all partially used pools holding small blocks with "size class idx" i. So
+usedpools[0] corresponds to blocks of size 8, usedpools[2] to blocks of size
+16, and so on:  index 2*i <-> blocks of size (i+1)<<ALIGNMENT_SHIFT.
+
+Pools are carved off an arena's highwater mark (an arena_object's pool_address
+member) as needed.  Once carved off, a pool is in one of three states forever
+after:
+
+used == partially used, neither empty nor full
+    At least one block in the pool is currently allocated, and at least one
+    block in the pool is not currently allocated (note this implies a pool
+    has room for at least two blocks).
+    This is a pool's initial state, as a pool is created only when malloc
+    needs space.
+    The pool holds blocks of a fixed size, and is in the circular list headed
+    at usedpools[i] (see above).  It's linked to the other used pools of the
+    same size class via the pool_header's nextpool and prevpool members.
+    If all but one block is currently allocated, a malloc can cause a
+    transition to the full state.  If all but one block is not currently
+    allocated, a free can cause a transition to the empty state.
+
+full == all the pool's blocks are currently allocated
+    On transition to full, a pool is unlinked from its usedpools[] list.
+    It's not linked to from anything then anymore, and its nextpool and
+    prevpool members are meaningless until it transitions back to used.
+    A free of a block in a full pool puts the pool back in the used state.
+    Then it's linked in at the front of the appropriate usedpools[] list, so
+    that the next allocation for its size class will reuse the freed block.
+
+empty == all the pool's blocks are currently available for allocation
+    On transition to empty, a pool is unlinked from its usedpools[] list,
+    and linked to the front of its arena_object's singly-linked freepools list,
+    via its nextpool member.  The prevpool member has no meaning in this case.
+    Empty pools have no inherent size class:  the next time a malloc finds
+    an empty list in usedpools[], it takes the first pool off of freepools.
+    If the size class needed happens to be the same as the size class the pool
+    last had, some pool initialization can be skipped.
+
+
+Block Management
+
+Blocks within pools are again carved out as needed.  pool->freeblock points to
+the start of a singly-linked list of free blocks within the pool.  When a
+block is freed, it's inserted at the front of its pool's freeblock list.  Note
+that the available blocks in a pool are *not* linked all together when a pool
+is initialized.  Instead only "the first two" (lowest addresses) blocks are
+set up, returning the first such block, and setting pool->freeblock to a
+one-block list holding the second such block.  This is consistent with that
+pymalloc strives at all levels (arena, pool, and block) never to touch a piece
+of memory until it's actually needed.
+
+So long as a pool is in the used state, we're certain there *is* a block
+available for allocating, and pool->freeblock is not NULL.  If pool->freeblock
+points to the end of the free list before we've carved the entire pool into
+blocks, that means we simply haven't yet gotten to one of the higher-address
+blocks.  The offset from the pool_header to the start of "the next" virgin
+block is stored in the pool_header nextoffset member, and the largest value
+of nextoffset that makes sense is stored in the maxnextoffset member when a
+pool is initialized.  All the blocks in a pool have been passed out at least
+once when and only when nextoffset > maxnextoffset.
+
+
+Major obscurity:  While the usedpools vector is declared to have poolp
+entries, it doesn't really.  It really contains two pointers per (conceptual)
+poolp entry, the nextpool and prevpool members of a pool_header.  The
+excruciating initialization code below fools C so that
+
+    usedpool[i+i]
+
+"acts like" a genuine poolp, but only so long as you only reference its
+nextpool and prevpool members.  The "- 2*sizeof(pymem_block *)" gibberish is
+compensating for that a pool_header's nextpool and prevpool members
+immediately follow a pool_header's first two members:
+
+    union { pymem_block *_padding;
+            uint count; } ref;
+    pymem_block *freeblock;
+
+each of which consume sizeof(pymem_block *) bytes.  So what usedpools[i+i] really
+contains is a fudged-up pointer p such that *if* C believes it's a poolp
+pointer, then p->nextpool and p->prevpool are both p (meaning that the headed
+circular list is empty).
+
+It's unclear why the usedpools setup is so convoluted.  It could be to
+minimize the amount of cache required to hold this heavily-referenced table
+(which only *needs* the two interpool pointer members of a pool_header). OTOH,
+referencing code has to remember to "double the index" and doing so isn't
+free, usedpools[0] isn't a strictly legal pointer, and we're crucially relying
+on that C doesn't insert any padding anywhere in a pool_header at or before
+the prevpool member.

+Arena management.
+
+`arenas` is a vector of arena_objects.  It contains maxarenas entries, some of
+which may not be currently used (== they're arena_objects that aren't
+currently associated with an allocated arena).  Note that arenas proper are
+separately malloc'ed.
+
+Prior to Python 2.5, arenas were never free()'ed.  Starting with Python 2.5,
+we do try to free() arenas, and use some mild heuristic strategies to increase
+the likelihood that arenas eventually can be freed.
+
+unused_arena_objects
+
+    This is a singly-linked list of the arena_objects that are currently not
+    being used (no arena is associated with them).  Objects are taken off the
+    head of the list in new_arena(), and are pushed on the head of the list in
+    PyObject_Free() when the arena is empty.  Key invariant:  an arena_object
+    is on this list if and only if its .address member is 0.
+
+usable_arenas
+
+    This is a doubly-linked list of the arena_objects associated with arenas
+    that have pools available.  These pools are either waiting to be reused,
+    or have not been used before.  The list is sorted to have the most-
+    allocated arenas first (ascending order based on the nfreepools member).
+    This means that the next allocation will come from a heavily used arena,
+    which gives the nearly empty arenas a chance to be returned to the system.
+    In my unscientific tests this dramatically improved the number of arenas
+    that could be freed.
+
+Note that an arena_object associated with an arena all of whose pools are
+currently in use isn't on either list.
+
+Changed in Python 3.8:  keeping usable_arenas sorted by number of free pools
+used to be done by one-at-a-time linear search when an arena's number of
+free pools changed.  That could, overall, consume time quadratic in the
+number of arenas.  That didn't really matter when there were only a few
+hundred arenas (typical!), but could be a timing disaster when there were
+hundreds of thousands.  See bpo-37029.
+
+Now we have a vector of "search fingers" to eliminate the need to search:
+nfp2lasta[nfp] returns the last ("rightmost") arena in usable_arenas
+with nfp free pools.  This is NULL if and only if there is no arena with
+nfp free pools in usable_arenas.

+ * effect, we're trying to force a useful implementation of C89 errno
+ * behavior.
+ * Caution:
+ *    This isn't reliable.  C99 no longer requires libm to set errno under
+ *        any exceptional condition, but does require +- HUGE_VAL return
+ *        values on overflow.  A 754 box *probably* maps HUGE_VAL to a

+ *        was an infinity and an infinity is the expected result.  A C89
+ *        system sets errno to ERANGE, so we check for that too.  We're
+ *        out of luck if a C99 754 box doesn't map HUGE_VAL to +Inf, or

+//--- HAVE_PY_SET_53BIT_PRECISION macro ------------------------------------
+//
+// The functions _Py_dg_strtod() and _Py_dg_dtoa() in Python/dtoa.c (which are
+// required to support the short float repr introduced in Python 3.1) require
+// that the floating-point unit that's being used for arithmetic operations on
+// C doubles is set to use 53-bit precision.  It also requires that the FPU
+// rounding mode is round-half-to-even, but that's less often an issue.
+//
+// If your FPU isn't already set to 53-bit precision/round-half-to-even, and
+// you want to make use of _Py_dg_strtod() and _Py_dg_dtoa(), then you should:
+//
+//     #define HAVE_PY_SET_53BIT_PRECISION 1
+//
+// and also give appropriate definitions for the following three macros:
+//
+// * _Py_SET_53BIT_PRECISION_HEADER: any variable declarations needed to
+//   use the two macros below.
+// * _Py_SET_53BIT_PRECISION_START: store original FPU settings, and
+//   set FPU to 53-bit precision/round-half-to-even
+// * _Py_SET_53BIT_PRECISION_END: restore original FPU settings
+//
+// The macros are designed to be used within a single C function: see
+// Python/pystrtod.c for an example of their use.
