10cd68e0f0 copy_tree: do not block on fifos
Fixes regression introduced in faeab50e71.

If a directory contains fifos, then openat blocks until the other side
of the fifo is connected as well.

This means that users can prevent "usermod -m" from completing if their
home directories contain at least one fifo.

cfc981df2a shadow: use relaxed usernames
The groupadd from shadow does not allow upper case group names, the
same is true for the upstream shadow. But distributions like
Debian/Ubuntu/CentOS has their own way to cope with this problem,
this patch is picked up from Fedora [1] to relax the usernames
restrictions to allow the upper case group names, and the relaxation is
POSIX compliant because POSIX indicate that usernames are composed of
characters from the portable filename character set [A-Za-z0-9._-].

ebf9b232b0 useradd: Do not reset non-existent data in {last,fail}log
useradd does not create the files if they don't exist, but if they exist
it will reset user data even if the data did not exist before creating
a hole and an explicitly zero'd data point resulting (especially for
high UIDs) in a lot of zeros ending up in containers and tarballs.

7136e24f8a Revert "Drop unused function subid_init()"
As rbalint points out, this was an exported fn.  It also is
the only way for a libsubid user to do what it does, so let's
not drop it.

This reverts commit 477c8e6f42.

faeab50e71 Avoid races in copy_tree()
Use *at() functions to pin the directory operating in to avoid being
redirected by unprivileged users replacing parts of paths by symlinks to
privileged files.

Introduce a path_info struct with the full path and dirfd and name
information for *at() functions, since the full path is needed for link
resolution, SELinux label lookup and ACL attributes.

fb96d3f84d useradd: make the option specstr passed to getopt_long extensible
It was hard to extend the option specification string passed to
getopt_long as the third argument.

The origian code had a branch with WITH_SELINUX ifdef condition. If
one wants to add one more option char with another ifdef condition
like ENABLE_SUBIDS to the spec, the one must enumerate the specs for
all combinations of the conditions:

*  WITH_SELINUX &&  ENABLE_SUBIDS
*  WITH_SELINUX && !ENABLE_SUBIDS
* !WITH_SELINUX &&  ENABLE_SUBIDS
* !WITH_SELINUX && !ENABLE_SUBIDS

With this change, you can append an option char to the spec.
