5e53a4f90f lib: further adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 2-Clause license, however the tool I
was using mis-identified 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.

7b3ea376a2 META MODE: Prefer INSTALL=tools/install.sh to lessen the need for xinstall.host.
This both avoids some dependencies on xinstall.host and allows
bootstrapping on older releases to work due to lack of at least 'install -l'
support.

4232f82668 Enforce overwritting SHLIBDIR
Since METAMODE has been added, sys.mk loads bsd.mkopt.mk which ends load loading
bsd.own.mk which then defines SHLIBDIR before all the Makefile.inc everywhere.

This makes /lib being populated again.

ccfb965433 Add META_MODE support.
Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.

Still need to add real targets under targets/ to build packages.

08f9924ec6 Properly use SHA1_Final() instead of SHA_Final().
In this case it doesn't really matter, as long as we turn a TTY name
into a set of shuffled bytes. Still, for correctness we should use the
proper function.

691ac623d7 Remove utmpx stub from libulog.
I'm not increasing the shlib major version for this, because not a
single application outside the base system should have used these
functions in such a short timespan.

Rewrite ulog_login(3) and ulog_logout(3) to build on top of the utmpx
implementation in libc.

a627ac61ab Implement <utmpx.h>.
The utmpx interface is the standardized interface of the user accounting
database. The standard only defines a subset of the functions that were
present in System V-like systems.

I'd like to highlight some of the traits my implementation has:

- The standard allows the on-disk format to be different than the
  in-memory representation (struct utmpx). Most operating systems don't
  do this, but we do. This allows us to keep our ABI more stable, while
  giving us the opportunity to modify the on-disk format. It also allows
  us to use a common file format across different architectures (i.e.
  byte ordering).

- Our implementation of pututxline() also updates wtmp and lastlog (now
  called utx.log and utx.lastlogin). This means the databases are more
  likely to be in sync.

- Care must be taken that our implementation discard any fields that are
  not applicable. For example, our DEAD_PROCESS records do not hold a
  TTY name. Just a time stamp, a record identifier and a process
  identifier. It also guarantees that strings (ut_host, ut_line and
  ut_user) are null terminated. ut_id is obviously not null terminated,
  because it's not a string.

- The API and its behaviour should be conformant to POSIX, but there may
  be things that slightly deviate from the standard. This implementation
  uses separate file descriptors when writing to the log files. It also
  doesn't use getutxid() to search for a field to overwrite. It uses an
  allocation strategy similar to getutxid(), but prevents DEAD_PROCESS
  records from accumulating.

Make sure libulog doesn't overwrite the manpages shipped with our C
library. Also keep the symbol list in Symbol.map sorted.

I'll bump __FreeBSD_version later this evening. I first want to convert
everything to <utmpx.h> and get rid of <utmp.h>.

daaf575910 Build lib/ with WARNS=6 by default.
Similar to libexec/, do the same with lib/. Make WARNS=6 the norm and
lower it when needed.

I'm setting WARNS?=0 for secure/. It seems secure/ includes the
Makefile.inc provided by lib/. I'm not going to touch that directory.
Most of the code there is contributed anyway.

4a1f09d742 Parse DEAD_PROCESS entries properly.
The TTY line name should always be set for DEAD_PROCESS entries right
now. When we parse a clean utmp entry, we don't want to interpret it as
a DEAD_PROCESS entry if the TTY has never been used yet.

444999a314 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.

bfa3a5e5bc Don't corrupt logout entries in utmp files.
An older version of the code used a structure on the stack, instead of a
pointer to the structure. It looks like I didn't adjust the parameters
of the write(2) call, causing the first four/eight bytes of the entry to
be corrupted, instead of writing the entire entry to disk.

6e8021eae1 Install libulog in /lib.
Because several applications in /bin use libulog (or may use it in the
nearby future), it must not live inside /usr. It seems like we don't
need to add the copy from /usr/lib to ObsoleteFiles.inc, because it's
cleaned up during installation of libulog automatically.

04b0c5bbfa Add a libutempter compatibility interface to libulog.
The ulog_login_pseudo(3) and ulog_logout_pseudo(3) interfaces provide a
functionality identical to what libutempter has to offer. Just transform
libutempter's calls into the before mentioned functions.

libutempter doesn't work with utmpx, so instead of fixing I thought the
easiest way would be to integrate this functionality. libutempter is
used by applications like xterm and the KDE libraries, so if I ever
change the underlying file format, these applications will keep working
automatically.

Also increase __FreeBSD_version to indicate the addition (as well as the
import of libulog).

42782e4717 Massively extend libulog:
- Just like struct utmp, store strings inside struct utmpx itself. This
  is needed to make things like pututxline() work.
- Add ut_id and ut_pid fields, even though they have little use in our
  implementation.
- It turns out our "reboot" wtmp entries indicate a system boot, so
  remove REBOOT_TIME
- Implement getutxline() and pututxline
- Add getutxuser() and setutxfile(), which allows us to crawl wtmp and
  lastlog files as well.
- Add _ULOG_POSIX_NAMES, so we can already use the POSIX names if we
  really want to.

178442d07a Use USER_PROCESS instead of LOGIN_PROCESS.
POSIX isn't clear about how the fields should be used, but according to
utmpx(5) on Linux, LOGIN_PROCESS refers to a TTY that's still running a
getty.

fab0a3c997 Also implement ut_type.
I thought we couldn't emulate this field, but we can derive this field
by looking at special values for ut_host, ut_line and ut_name.

2208eadf43 Add a new library: libulog.
One of the things I really want to do, is to get rid of the limitations
of our current utmp(5) mechanism:

- It only allows 8 byte TTY device names.
- The hostname only allows 16 bytes of storage.

I'm not a big fan of <utmpx.h>, but I think we should at least try to
add parts of it. Unfortunately we cannot implement <utmpx.h>, because we
miss various fields, such as ut_id, ut_pid, etc. The API provided by
libulog shares some similarities with <utmpx.h>, so it shouldn't be too
hard to port these applications eventually. In most simple cases, it
should just be a matter of removing the ulog_ prefix everywhere.

As a bonus, it also implements a function called ulog_login_pseudo(),
which allows unprivileged applications to write log entries, provided
they have a valid file descriptor to a pseudo-terminal master device.

libulog will allow a smoother transition to a new file format by adding
a library interface to deal with utmp/wtmp/lastlog files. I initially
thought about adding the functionality to libutil, but because I'm not
planning on keeping this library around forever, we'd better keep it
separated.

Next items on the todo list:

1. Port applications in the base system (and ports) to libulog, instead
   of letting them use <utmp.h>.
2. Remove <utmp.h>, implement <utmpx.h> and reimplement this library on
   top.
3. Port as many applications as possible back to <utmpx.h>.
