usr.bin/who.c: Fix boot time checking

The boot time entry doesn't have a tty specified, so don't check it.
While here, make ttystat handle that case.

various: general adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

No functional change intended.

Pull in the virtio drivers from head.

Add the XSI option -b to show date of the last reboot.

That required to increase the LINE field to fit the output of -b.
While here, change the row() function to take a const argument.

Perform all trivial ports to utmpx for usr.bin/.

They were already converted to use libulog, so it's easy to convert them
to utmpx.

Merge from head at r201628.

# This hasn't been tested, and there are at least three bad commits
# that need to be backed out before the branch will be stable again.

Several refinements to libulog's API.

- Only set the fields in the ulog_utmpx structure that are valid for the
command in question. This means that strings like "shutdown" or "~"
are not visible

Several refinements to libulog's API.

- Only set the fields in the ulog_utmpx structure that are valid for the
command in question. This means that strings like "shutdown" or "~"
are not visible to the user anymore.
- Rename UTXF_* to UTXI_*, indicating the indexation, instead of using
the `antique' filename. If we ever get rid of utmp, it makes little
sense calling it by its old name.

Revert most part of 200420 as requested, as more review and polish is

Remove unneeded header includes from usr.bin/ except contributed code.

Port who(1) to utmpx.

(Un)fortunately there is no standardized interface to switch between
utmp database files, so we must call ulog_setutxfile() here.

I'm also changing the column widths to magic

Port who(1) to utmpx.

(Un)fortunately there is no standardized interface to switch between
utmp database files, so we must call ulog_setutxfile() here.

I'm also changing the column widths to magic numbers here. Display
layout should in this case not be derived from structure fields sizes.
Because I don't want struct utmpx ever to become too small, the fields
are too big to reserve all the space.

In wall and who, check that the utmp entry isn't stalled, as it is done in w.
Apparently with the new pts code stalled entries are printed, when they are
not with the BSD ptys.

Move variable initialization to reduce compiler warning.

Fix a warning that showed up on 64 bit systems. It was actually a real
bug that had been swept under the carpet.

Remove unimplemented System V options from the getopt() option string.

utmp.ut_time and lastlog.ll_time are explicitly int32_t rather than
time_t. Deal with the possibility that time_t != int32_t. This boils
down to this sort of thing:

utmp.ut_time and lastlog.ll_time are explicitly int32_t rather than
time_t. Deal with the possibility that time_t != int32_t. This boils
down to this sort of thing:
- time(&ut.ut_time);
+ ut.ut_time = time(NULL);
and similar for ctime(3) etc. I've kept it minimal for the stuff
that may need to be portable (or 3rd party code), but used Matt's time32
stuff for cases where that isn't as much of a concern.
