Phillip Lougher ac51a0a713 Squashfs: add sanity checks to lookup table reading at mount time
Fsfuzzer generates corrupted filesystems which throw a warn_on in
kmalloc.  One of these is due to a corrupted superblock inodes field.
Fix this by checking that the number of bytes to be read (and allocated)
does not extend into the next filesystem structure.

Also add a couple of other sanity checks of the mount-time lookup table
structures.

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.

Pekka Enberg 23516dc709 kmemtrace, squashfs: fix slab.h dependency problem in squasfs
Impact: cleanup

fs/squashfs/export.c depends on slab.h without including it:

    CC      fs/squashfs/export.o
  fs/squashfs/export.c: In function ‘squashfs_read_inode_lookup_table’:
  fs/squashfs/export.c:133: error: implicit declaration of function ‘kmalloc’
  fs/squashfs/export.c:133: warning: assignment makes pointer from integer without a cast
  fs/squashfs/export.c:143: error: implicit declaration of function ‘kfree’
  make[1]: *** [fs/squashfs/export.o] Error 1
  make: *** [fs/squashfs/] Error 2

It gets included implicitly currently - but this will not be the
case with upcoming kmemtrace changes.
