rc.d/serial: Kill dtrwait

The dtrwait wait functionality was dropped in the TTY MPSAFE rewrite for
FreeBSD 8. Remove referneces to it here. Also, the sysctl was renamed
for drainwait, so use the new name. Given the 16 years between this
event and somebody noticing, I strongly suspect this file can just be
removed.

rc.d/serial: Remove removed drivers.

Cyclades and digiboard drivers were removed in 2017 and 2016
respectively. There's no need for these anymore.

Use 115200 bps by default for serial communication

9600 was a standard baud rate decades ago, but 115200 is now more common
so choose defaults that are useful to the largest number of users.

Note that boot0sio does not support rates above 9600 so it remains
unchanged.

Move the rc framework out of sbin/init into libexec/rc.

The reasons for this are forward looking to pkgbase:
* /sbin/init is a special binary; try not to replace it with
every package update because an rc script was touched.
(a follow-up commit will make init its own package)
* having rc in its own place will allow more easy replacement
of the rc framework with alternatives, such as openrc.

This keeps most startup scripts as CONFS per discussion on src-committers from
back during BSDCan.

With uart(4) default, change /dev/cuad# to /dev/cuau# and
sio# to uart# so that out-of-the-box FreeBSD is consistent.

As previously discussed, add the svn:executable property to all scripts

Add an example of how to set up a 3-wire serial terminal.
Usually, getty(8) does the trick, but if you just need a
serial console without getty(8), here's how.

Unify the ci/co variables now that the the tty drivers now use the same
character for both.

Catch up with PHK's sio(4) rework [sys/dev/sio/sio.c rev. 1.456].

Remove the requirement for the FreeBSD keyword as it no longer
makes any sense.

Mark scripts as not usable inside a jail by adding keyword 'nojail'.

Some suggestions from: rwatson, Ruben de Groot <mail25@bzerk.org>

Catch up with 1995(?) for modem speeds (use 57600 instead of 115200 for
the example host to modem speed).

When resetting to defaults, reset drainwait to the current default pf
`sysctl -n kern.drainwait` instead of to the boot-time default of 300.

Fix style bugs:
* Space -> tabs conversion.
* Removed blanks before semicolon in "if ... ; then".
* Proper indentation of misindented lines.
