Write an empty /etc/machine-id instead of writing 'uninitialized'. 
Writing "uninitialized" instructs systemd to run units with
ConditionFirstBoot=yes which should only be done by tools that know how
to correctly set up such units.

Remove support for proot. 
The proot mode was broken from the start because in contrast to
fakechroot, no ownership information can be retained across multiple
invocations of proot. Since mmdebstrap started using apt from the
outside by setting DPkg::Chroot-Directory in mmdebstrap 0.8.0 proot mode
was finally completely broken because proot cannot wrap the chroot call
done by apt. Users of proot are recommended to run mmdebstrap in
fakechroot mode and then use proot with the resulting directory.

mmdebstrap: Show APT's dependency trace when in debug mode 
A dependency trace is a powerful tool to debug issues related to
APT's selection of packages, especially in custom mode.

Thus it makes sense to ask APT to output a dependency trace when
`mmdebstrap` is run with the `--debug` flag.

Adjust merged-/usr as it's done by debootstrap 
- implements the same as debootstrap in
   https://salsa.debian.org/installer-team/debootstrap/-/merge_requests/71
 - builds a temporary usr-is-merged package and upgrades to the real one
 - create merged-/usr chroots for unstable and testing (which will
   become Debian 12 Bookworm)
 - add a dedicated merged-/usr section to the manual page

Mount a new instance of /dev/pts in the chroot 
Before, we bind-mounted /dev/ptmx and /dev/pts from the host into the
chroot. This will make posix_openpt() fail with 'No such file or
directory'.  The ability to create pseudo terminals is important for apt
(which will throw a warning otherwise) or running script(1) or source
package testsuites like for src:util-linux. This functionality is
restored by mounting a new devpts instance to /dev/pts and making
/dev/ptmx a symlink to /dev/pts/ptmx. Mounting with ptmxmode=666 is
required such that also non-root users in unshare mode are able to
create pseudo terminals. See also:

Only set up FAKECHROOT_CMD_SUBST for paths in PATH containing the original binary 
If FAKECHROOT_CMD_SUBST sets up wrong substitutions, then binaries
cannot be found. For example if /usr/bin/chroot is listed in
FAKECHROOT_CMD_SUBST but /usr/sbin (the actual location of the chroot
binary) is not in PATH, the command fails

David Kalnischkies cc3150ef04
Rework download stage to allow file:// mirrors 
- factor out package downloading function
 - replace -oApt::Get::Download-Only=true by -oDebug::pkgDpkgPm=1
 - remove guessing of package names in /var/cache/apt/archives/
 - drop edsp parsing with proxysolver/mmdebstrap-dump-solution to obtain
   downloaded filenames in favour of -oDpkg::Pre-Install-Pkgs::=cat
 - /var/cache/apt/archives/ is now allowed to contain packages
 - drop --skip=download/empty
 - file:// mirrors are now supported if their path is available inside
   the chroot

manually push option arguments to array instead of using s@ 
By mixing s@ for --$foo-hook options and manual pushing in --hook-dir,
it can happen that options get lost. Consider the following test:

use Getopt::Long;
my $arr = [];
GetOptions(
    'A=s@' => \$arr,
    'B=s' => sub { push @{$arr}, $_[1]; }
);
foreach my $hook (@{$arr}) { print "hook: $hook\n"; }

This works fine:

    perl test.pl --A=a1 --B=b1 --A=a2 --B=b2
    hook: a1
    hook: b1
    hook: a2
    hook: b2

This misses b1:

    perl test.pl --B=b1 --A=a2 --B=b2
    hook: a2
    hook: b2
