nsenter: allow to use --set{uid,gid} for all namespaces
Now it's possible to set UID and GID for user namespaces only. This
patch removes this restriction and allow to use --set{uid,gid} in all
cases. The default for user namespaces is still GID=0, UID=0.

When tailf is not using inotify, it seems to sleep for 0.25s between
checks. Just giving a 0.1s time window between update and removal of the
input file thus gives little chance for tailf to succeed.
Similar between startup and append to file, make sure initial
content is read before appending additional data by bumping the time.
This should possibly be bumped much larger to make sure that
the tailf process actually gets a chance to run at all in the
given time window. Otherwise it might fail on really slow/overloaded
machines.
The drawback would then ofcourse be to increase the time it takes
to run the testsuite.

logger: add hostname to rfc3164 message
This makes the obsolete protocol a little bit more compliant with the
internet standard, but few should care now when we have rfc5424 support,
and rfc3164 feels broken. For example it requires hostname to be not
fully qualified, which is hard to understand, and should make users to
prefer the new protocol.

agetty: Reprompt and reprint /etc/issue when asked
Add an 'agetty --reload' command which asks all running agetty
commands to display their prompts again.
Several of the /etc/issue escape codes such as \4 and \S depend on
variable data which can change after the agetty prompt is displayed.
This can cause stale data to be displayed when a user looks at a VT,
especially in cases of DHCP racing with system start up.
We never want this to occur once the user has started typing a
user name. So we detect when the user starts typing, after which
no further reprompting occurs after that point.

This change moves the code from swaplabel(8) to shared scope to be used

Adding this feature to lsblk(8) was a consideration, but lsblk is not
interested of swapfiles, so the swapon seems like a better option to add
this information.
