We use a str_table_t to generate unique IDs for all unique keys and all
unique values and then use a post processing step to deduplicate xattr
listings.

Turns out (after countless hours of debugging since the squashfs kernel
code is so convoluted) that the offset is relative to the first directory
header for no apparant reason (the field holding the offset is way larger
than neccessary to store absolute values).

- gensquashfs simply asks the backend compressor to write its options
to the file and does accounting
- rdsquasfs simply asks the backend compressor to transparentyl snort
the options from the file
- not implemented in any compressor backend yet

- accept "nod" line as advertised, i.e. with space instead of colon
- actually accept "sock" line (copy & paste fail)

The listing command has been used successfully to do the following:
- generate a prestine file system using gensquashfs
- repeate multiple times:
- generate a listing from the file system
- unpack only the regular files from the file system
- generate a new file system from the listing
- run `diff` on the old and new filesystem and admire that they
are identical
- replace the old file system with the new one, since they are
identical

Instead of malloc/freeing the buffers for every file, allocate them
once, ahead of time.

This commit changes the names of the tools to gensquashfs and rdsquashfs
so they don't collide with the names used by the squashfs-tools package
and the two can be installed side by side.

Stick to the terminology that SquashFS uses. SquashFS uses "lzma" to
refere to lzma1, "xz" to refere to lzma2 and confusingly "gzip" to
refere to raw zlib deflate. We can avoid a lot of confusion by
_consistently_ using the same terminology.

Pass in an external destination buffer + size and allow for propper
bounds checking (especially when unpacking).

This allows the user to skip stuff like device special files (which
non-root can't create anyway) or to not create symlinks/fifos etc...

Behave somewhat like `ls -l' does by printing the size of the
entry (or major/minor device number for devices) between the UID/GID
column and the name column.
For symlinks, print and arrow and the symlink target after the name.
