Remove libpostproc.

This library does not fit into Libav as a whole and its code is just a
maintenance burden.  Furthermore it is now available as an external project,
which completely obviates any reason to keep it around.

-TODO:
-reduce the time wasted on the mem transfer
-unroll stuff if instructions depend too much on the prior one
-move YScale thing to the end instead of fixing QP
-write a faster and higher quality deblocking filter :)
-make the mainloop more flexible (variable number of blocks at once
-        (the if/else stuff per block is slowing things down)
-compare the quality & speed of all filters
-split this huge file
-optimize c versions
-try to unroll inner for(x=0 ... loop to avoid these damn if(x ... checks
