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.
- 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.
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.
This brings hwpmc(4) support for 2nd and 3rd generation XScale cores.
Right now it's enabled by default to make sure we test this a bit.
When the time comes it can be disabled by default.
Tested on Gateworks boards.

The race condition is believed to be in UMTX_OP_MUTEX_WAKE. On ia64,
we simply go to the kernel to unlock.
The big question is why this is only a race condition on ia64...

The information used by the "Last login:"-line is obtained by using
ulog_setutxfile(3) to switch to the lastlog database. Login and logout
are performed using the utility functions ulog_login(3) and
ulog_logout(3).
This also means we must build libulog during bootstrap.

1) Avoid an infinite loop in the header resync for certain malformed
archives.
2) Don't try to match hardlinks if the nlinks count is < 2. This
reduces the likelihood of a false hardlink match due to ino truncation.

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.

instead of returning an error if a corrupt (not a "name=value" string) entry
in the environ array is detected when (re)-building the internal
environment. This should prevent applications or libraries from
experiencing issues arising from the expectation that these calls will
complete even with corrupt entries. The behavior is now as it was prior to
7.0.

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).
