Remove the -r option, forcing the user to explicitly pass a root
directory. This removes some confusion wherein we set defaults, but
wouldn't allow all the defaults to be accepted.
This also adds some mild documentation to the help output for genfstab
and pacstrap.
The %b formatter is too generic for us to use, as a sequence such as
'\b' is invalid for hex escaping, but valid for %b. Port over the logic
from util-linux's mangle mini-lib and use this instead. This supports
both 3 digits hex as well as 3 digit octal escapes, and will ignore the
more generic ascii based single character escapes. Output is always in
octal format to comply with fstab(5).
* the Makefile uses m4 to build the common lib into the scripts
* it includes install, uninstall and clean targets
* the dist target creates a source tar from a tag
