Add zlib (v1.2.11) uncompr() function to U-Boot. SquashFS depends on this function to decompress data from a raw disk image. The actual support for zlib into SquashFS sources will be added in a follow-up commit.

Can you confirm that on a platform where we aren't enabling squashfs the new zlib functionality ends up being discarded at link time? Thanks!
I dumped lib/zlib/zlib.o with readelf and the new functionality is not discarded, even though the SquashFS support is not enabled, but this issue will be fixed in the next version (v4). Thank you!
Well, don't dump lib/zlib/zlib.o, that won't say. Check u-boot.map :)
