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

+WINDOWS DEFINES:
+The code specific to Windows should be wrapped around one of
+the following #defines
+
+MS_WIN64 - Code specific to the MS Win64 API
+MS_WIN32 - Code specific to the MS Win32 (and Win64) API (obsolete, this covers all supported APIs)
+MS_WINDOWS - Code specific to Windows, but all versions.
+Py_ENABLE_SHARED - Code if the Python core is built as a DLL.
+
+Also note that neither "_M_IX86" or "_MSC_VER" should be used for
+any purpose other than "Windows Intel x86 specific" and "Microsoft
+compiler specific".  Therefore, these should be very rare.
+
+
+NOTE: The following symbols are deprecated:
+NT, USE_DL_EXPORT, USE_DL_IMPORT, DL_EXPORT, DL_IMPORT
+MS_CORE_DLL.
