The problem: SquashFS uses extended inode types for inodes with xattrs,
so for directories we need to generate an ldir inode. The ldir inode
type includes a directory index which cannot be empty (the counter is
off by 1, so 0 means 1 entry) and the entry is expected to contain a
file name with the same issue (must be at least 1 byte).
This has probably not really been thought through. What the mksquashfs
actually does is generating an ldir inode without an index. The kernel
does not bother to read the index, since the size of the directory is 0.
Its a hack that just so happens to work.

If packdir and packfile are both specified, use packdir as
alternate root.

For now, it is enough to reduce the comparison value, since the inode
numbers are increasing.

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

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.
