libmount: improve fs referencing in tables
* Added member 'struct libmnt_table *tab' to libmnt_fs structure.
* Added 'mnt_fs_get_table()'.
* Removed overhead from 'mnt_table_{insert,move,remove}_fs().
* Added check to 'mnt_table_set_iter()' that entry is member of table.
[kzak@redhat.com: - add to libmount.sys
- add to docs
- cleanup commit message
- set fs->tab = NULL before mnt_unref_fs() in mnt_table_remove_fs()]

In commit b22332dd4 (last: fix wtmp user name buffer overflow
[asan], 2019-01-13), we started to make sure that the `ut_user`
field of the `utmpx` struct is always NUL-terminated. The
implementation makes use of the `__UT_NAMESIZE` define to
determine the position of the last character in that array. The
problem is that this is a non-standard define that is not
necessarily available on non-glibc platforms.
As there is no standardized define, we should just use `sizeof`.
This fixes compilation on musl libc based systems.

agetty: Fix input of non-ASCII characters in get_logname()
As login supports non-ASCII characters in the logname, agetty should be
consistent.
8b58ffdd re-activated old and ASCII-only get_logname(), which restricted
the input to ASCII only. As the code does not read whole characters,
isascii(ascval) and isprint(ascval) returns nonsenses after entering a
non-ASCII character.
As keyboard maps don't contain unprintable non-control characters, it
seems to be relatively safe to remove both checks.

column: Address fill-order confusion in documentation
Historical versions of column have described the default fill order as
rows-then-columns and the -x order as columns-then-rows. This was
misleading at best, and the util-linux implementation was updated to
clarify the actual behaviour in 3e094e5fe2 (March 2017).
However, the other implementations (used by *BSD, macOS, Debian, &al.)
continue to use the previous wording, and a user comparing them could
easily get the false impression that util-linux column has exactly the
opposite fill behaviour from BSD column.
To address this, a note is added to the man page explaining the change
and clarifying that, despite what the BSD documentation says, the two
implementations behave identically in this regard.

It is not guaranteed that the returned string of readline() actually
contains as many bytes as buf can contain.
If bufsz is larger than the allocated memory by readline, an out of
boundary read occurs and leads to undefined behaviour. Most likely
that will be a crash.
This can be reproduced when readline-support is compiled in and when
you directly enter "quit" and "n" (to not write changes back to disk)
when sfdisk was called with any given device.

This patch fixes c->c_column = cur_col; where c_column is "short"
