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

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

Run File::Find::find with no_chdir=>1 
Without no_chdir=>1 the unshared child process in unshare mode needs
read permissions for the directory from which mmdebstrap is executed.
With this change, the current working directory does not need to be
world-readable anymore.

c61e81a244 Relax dpkg version regex 
For non-release builds the version will include the number of commits since last release and the commit hash with dashes, e.g. 1.20.8-46-g0881.
For downstream distros it seems it may include their identification strings, e.g. 1.20.9ubuntu2.

Make the regex match everything after the version number to avoid incorrectly erroring on such versions.

use rm and find instead of remove_tree() 
* remove_tree() requires the CWD to be accessible or fails with
   cannot chdir to $CWD from $DIR_TO_DELETE: Permission denied, aborting.
 * CWD is not always accessible -- example: run mmdebstrap from a
   directory only accessible by the current user (like a tempdir) in
   unshare mode
 * find from findutils *also* requires CWD to be accessible but it's
   easier to temporarily change CWD in a subprocess because using
   there is no utility in perl core that changes CWD temporarily and
   cleans up after itself
 * we need to use find from findutils instead of rm in unshare mode
   because the root directory itself might not be removable by the
   unshared user so we only want to remove its subdirectories
