algorithms to be cleanly supported.

Also update zlib wrapper and other code to use the new framework.

f1a40359f8 Squashfs: factor out remaining zlib dependencies into separate wrapper file
Move zlib buffer init/destroy code into separate wrapper file.  Also
make zlib z_stream field a void * removing the need to include zlib.h
for most files.

118e1ef6fa Squashfs: Fix oops when reading fsfuzzer corrupted filesystems
This fixes a code regression caused by the recent mainlining changes.
The recent code changes call zlib_inflate repeatedly, decompressing into
separate 4K buffers, this code didn't check for the possibility that
zlib_inflate might ask for too many buffers when decompressing corrupted
data.
