Piggyback on systemd-nspawn's --bind and --bind-ro flags to allow
arbitrary mount points to be added to the build container.

We can't rely on PKGEXT since it's not sourced from a controlled
location. Case in point, if a user sets PKGEXT=.pkg.tar.gz, checkpkg
fails and offers no easy workaround.

Instead, use glob expansion to resolve the name of the tarball, bailing
if it can't be found definitively. This involves some refactoring to
avoid modifying PWD (which is advisable regardless).

This fixes various errors one might encounter when trying to use a
build root or cachedir with whitespace in it.

Note that the cachedir fix is not a complete one, as pacman's output is
unreliable (and not meant for parsing here).

eval is no longer involved in the execution of systemd-nspawn, so we no
longer need a layer of escaping on the arguments.

For example...

$ make

Now that die() properly forwards arguments to error(), we can expect
that the first arg is a format string and not the entirety of the
output.

Also allow this function to be called without arguments, in which case,
don't call error at all. Some uses of this function wrongly assumed
that this was already allowed.

Nymeria's HTTP mirror is now password-protected and crossrepomove broke.

The user-passed makechrootpkg_args may contain a "--" to pass
arguments to makepkg. In this case, the order is wrong.

systemd-nspawn always outputs some debug messages over stderr.
Both stdout and stderr from inside the chroot are sent through
a pty to stdout.

Now syntax highlighting works properly! :D

For pkgver updates.

Allows calling makechrootpkg without worrying about the architecture

 - Ensure sources are available before entering chroot
 - Bind STARTDIR and SRCDEST into the chroot read-only
 - Refactor makechrootpkg and introduce meaningful functions

Avoids copying stuff from/to the chroot as much as possible. With
VCS sources these copies can get quite expensive.

I don't think this is much use in our common workflow. Our pacman
configs don't even make a reference to /repo.

Reduces code duplication.

With makechrootpkg not calling mkarchroot anymore,
the lock handover protocol is unneeded.

arch-nspawn does not do any locking, so add protection to archbuild.

Recent changes to systemd-nspawn have it take the machine name from
the chroot dir name, which isn't unique enough for our setup.

Separates the two features of mkarchroot. Provides users of the new
arch-nspawn with the full feature set of systemd-nspawn.

For example, this can be used to bind custom directories into the chroot.

Add option -T to build in a temporary chroot. This apply to any kind of
filesytem and allow to easily parrallelize builds.

This patch also simplify how $default_copy and $copy are defined.

systemd-nspawn is capable of doing this as of systemd-198. Doing this
means we can remove all of our home grown chroot mount/umount logic, as
it's all performed by pacstrap or systemd-nspawn.
