- Copy stable/10 (r259064) to releng/10.0 as part of the
10.0-RELEASE cycle.
- Update __FreeBSD_version [1]
- Set branch name to -RC1

[1] 10.0-CURRENT __FreeBSD_version value ended at '55', so
start releng/10.0 at '100' so the branch is started with
a value ending in zero.

Allow custom files to be opened and allow sorting by timestamp.

While implementing a tool to import lastlog entries into utmpx, I
noticed lastlogin doesn't allow custom database files to be opened. Add
a -f switch to support this. Also, add -r and -t similar to ls(1),
ruptime(1), etc. where you can sort entries by timestamp and reverse
them. This allows you to spot active/idle users more easily.

Don't forget to catch realloc() errors.

Alphabetically sort the output of lastlogin(8).

According to the manpage, the entries have to be sorted by uid. This is
no longer possible, since our utmpx implementation is completely unaware
of user IDs. You can safely add entries for multiple users sharing the
same uid.

Make the output less random by sorting everything by name.

Chop off excessive long hostnames to keep the table structure intact.

This makes lastlogin(8) use exactly the same printf format as last(1).

Remove unneeded setpassent() calls.

lastlogin no longer requires the use of the passwd database.

Remove stale references to utmp(5) and its corresponding filenames.

I removed utmp and its manpage, but not other manpages referring to it.

Port lastlogin(8) to utmpx.

While there, fix a bug I introduced previously. We must reopen the
database for each username passed on the command line. We must rewind
the database and search from the beginning.

The last big commit: let usr.sbin/ use WARNS=6 by default.

ANSIfy almost all applications that use WARNS=6.

I was considering committing all these patches one by one, but as
discussed with brooks@, there is no need to do this. If we ever
need/want to merge these changes back, it is still possible to do this
per application.

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.

Port lastlogin(1) to libulog.

Just use ulog_getutxuser() to obtain lastlog records or ulog_getutxent()
to browse through all of them.

Mechanically kill hard sentence breaks.

The .Nm utility

de-__P()

Fixed some world breakage caused by not updating clients when <timeconv.h>
was split off from <time.h>. This became fatal here when -Werror was
reenabled.

Don't depend on <pwd.h> to bogusly include <sys/types.h>.

I've been meaning to do this for a while. Add an underscore to the
time_to_xxx() and xxx_to_time() functions. e.g. _time_to_xxx()
instead of time_to_xxx(), to make it more obvious that these are
stopgap functions & placemarkers and not meant to create a defacto
standard. They will eventually be replaced when a real standard
comes out of committee.

Fix ctime(&int) due to change to lastlog->ll_time

Perform a major cleanup of the usr.sbin Makefiles.
These are not perfectly in agreement with each other style-wise, but they
are orders of orders of magnitude more consistent style-wise than before.

Set WARNS=2 on programs that compile cleanly with it; add $FreeBSD$
where necessary.
