- 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.

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

Apply s/LIBC_R/LIBPTHREAD/ to the DPADD variable. The LDADD variable
already had s/libc_r/libpthread/ applied to it.

s/-lc_r/-lpthread/

style.Makefile(5)

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.

Remove GCC'isms in CFLAGS.

- Backout botched attempt to introduce MANSECT feature.
- MAN[1-9] -> MAN.

Set the default manual section for usr.sbin/ to 8.

-pthread -> -lc_r

Change interactive mode so that a monitor thread keeps an eye on the
ppp descriptor and signals the terminal thread when there's something
to read on that descriptor.

This means that the main loop doesn't have to alarm() itself into
dropping out of el_gets() frequently to check the descriptor. This
dropping out was disturbing syscons (via ioctl()s from libedit) enough
to reset the screensaver timeout every .5 of a second.

libutil is no longer required as setproctitle() has moved to libc

If the -p option is used, use setproctitle() to hide it's argument
(a password) asap.

$Id$ -> $FreeBSD$

Remove OpenBSD build support - let the Makefile vary per
OS rather than making it a mess and potentially screwing
up cross builds.
Suggested by: bde

Add OpenBSD build support
Remove -Wmissing-prototypes

Style police.
bzero -> memset
index -> strchr
rindex -> strrchr
Use libedit (this should make pppctl a lot more attractive than telnet).

Allow command line control of ppp through both
TCP and AF_LOCAL sockets.
