00db5541e9 file list sort: remove duplicate directory entries
Can happen when merging multiple packages. But make sure they actually
are duplicates.

96d4d353d4 Remove unnecessary flush from unpacking loop
The uncompressor will know when end of file is reached. Flushing
prematurely won't help. Especially the way the loop was constructed,
using an external buffer that is a lot larger than the internal
buffer of the compressor will cause multiple erroneous flushes.

d94bd8ff17 pkg2sqfs: sort directory entries asciibetically
The squashfs kernel implementation relies on the following properties:
 - directory entries are ordered asciibetically by name
 - directory entries have consecutive inode numbers
 - inode numbers are assigned in that order

858779e42c Add pkg2sqfs utility stub
The goal is to transform a package file to a squashfs image. The mksquashfs
utility is a PITA with all kinds of idiotic not-thought-through corner
cases (e.g. the way "pseudo file definitions" have been tacked on, the
inabillity to set UID/GID for / *AND* have files not owned by root, the
way xattrs are handled, .....).

It would be preferable to fix mksquashfs itself, but the source code itself
is a horrid, unmaintained garbage pile. Its easier to write a small utility
instead that can turn a pkg file into a squashfs image in a way that
propperly treats file permissions and ownership, and is deterministic
(i.e. reproducable).

The utility currently generates an uncompressed squashfs image that
unsquashfs can unpack, but the kernel refuses the mount. The exact
problem still needs to be determined.

Furthermore, compression has to be implemented and some cleanup shoul
be done.
