Ajeet Yadav d7fbd89338 Squashfs: optimise squashfs_cache_get entry search
squashfs_cache_get() iterates over all entries to search for
 block its looking for. Often get() / put() are called for
 same block.

If we cache the current entry index, then we can optimise the
subsequent *_get() calls.

Phillip Lougher 8fcd97216f Squashfs: move squashfs_i() definition from squashfs.h
Move squashfs_i() definition out of squashfs.h, this eliminates
the need to #include squashfs_fs_i.h from numerous files.

Phillip Lougher 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.

Doug Chapman a37b06d589 Squashfs: fix breakage when page size > metadata block size
Squashfs is broken on any system where the page size is larger than
the metadata size (8192).  This is easily fixed by ensuring cache->pages
is always > 0.

Phillip Lougher 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.
