Squashfs: add a decompressor framework This adds a decompressor framework which allows multiple compression algorithms to be cleanly supported. Also update zlib wrapper and other code to use the new framework. Signed-off-by: Phillip Lougher <phillip@lougher.demon.co.uk>

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.

squashfs: fix potential buffer over-run on 4K block file systems Sizing the buffer based on block size is incorrect, leading to a potential buffer over-run on 4K block size file systems (because the metadata block size is always 8K). This bug doesn't seem have triggered because 4K block size file systems are not default, and also because metadata blocks after compression tend to be less than 4K.
