By default chroot uses SHELL as default shell on the target if not specified otherwise.
As our install iso uses zsh this might fail if zsh is not installed on the target.
[dave: changed shell to /bin/sh]
chroot(1) will default to ${SHELL:-/bin/sh} which might not work, given
SHELL being /bin/zsh instead. Immediately default to /bin/sh, which will
exist in any sane chroot.
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.
This mainly fixes the case where there's devices mounted under the
chroot directory. Creating a bind mount on top of this will obscure
these other mounts.
However, add a '-c' switch to use the host cache instead. The default is
useful for when installing a system from an install media (which has
possibly constrained storage), but the '-c' switch is useful when
e.g. creating build-chroots.
I considered doing this the other way around ('-c' being the default).
However, I think it makes sense to default to the expected behavior for
install both because a new user is less likely to know that they need to
add a switch, and because the errormessage they'd get when they run out
of space/memory is nonsensical and would cause lots of annoying
questions.

This would overwrite an existing mirrorlist, but the one at the host
is known to be good at this point, so the loss is minimal.

We want to be able to call pacstrap with the target being an existing
install (in case it has been severely broken), and hence we might want
to preserve the existing keyring.

the api_mount function could, for some bizzare reason, fail midway
through, leaving the user with a half mounted chroot. set the trap
before the function instead, but mask errors since we might see "foo
not mounted" errors.
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
