commit aa916c1eabdc1579fc31e7ff12254df478cc9a14

provide a basic /dev tree even in unprivileged namespaces
Most piuparts environments will provide a working /dev tree. For
instance, a pbuilder base.tgz contains them. As does a schroot tree.
Likewise, docker will set up devices. Even debootstrap will create them.
However when running piuparts in an unprivileged namespace, debootstrap
cannot create them (and can be made to work by exporting container=lxc).
Similarly, when passing a device-less base.tgz for an unprivileged
namespace they are missing. While piuparts previously created /dev/null,
this is bound to fail with -EPERM. In that case, individual device nodes
need to be bind mounted. Since such bind mounting is not preferred for
the other variants, we try creating missing devices first.

allow using tarballs compressed with non-gzip
The extension of the filename given to --basetgz with or without --save
will be checked for known compression formats by tar. Therefore gzip
tarballs must now have a suffix of .gz or .tgz.
commit 13d93cee834f0a76f225f607af0fb0c216258b80

allow using --bindmount with things that are not directories
While typically think of directories when it comes to mounting, one can
also mount regular files or devices. Doing so only works when the mount
target is not a directory though and piuparts kindly creates such
directories. So when the mount options reveal that we're doing a bind
mount and the source is not a directory, we create an empty file
instead.

make --bindmount recursive
When performing a bind mount, Linux will not do so recursively by
default. So if a subdirectory of the provided bind mount is a mount
point itself, this mount point will not be propagated and the underlying
hierarchy will be exposed inside piuparts. This may be intentional, but
likely is not.
Since a bind mount may be used to access a hierarchy that was hidden by
another mount, bind mounts are denied in unprivileged namespaces. On the
other hand, recursive bind mounts just work there.

improve compatibility of mount_proc with unprivileged namespaces
When run in an unprivileged namespace, both the mknod and the mount
operation may be denied and piuparts may fail here. Looking deeper, this
branch happens when /dev/ptmx is not already a symlink and what is bind
mounted can be expressed as a symlink, so opt for implementing this
device as a symlink when it is missing entirely. If nothing else, one
less mount invocation is a minor speedup.
