MFC r314226:

Use SRCTOP instead of .CURDIR relative paths with ".."

This simplifies pathing in make/displayed output

Copy head (r256279) to stable/10 as part of the 10.0-RELEASE cycle.

This isn't WARNS=6 safe. It fails to build on mips. Retore old
WARNS?=3 until that's resolved.

jh pointed out that src/usr.sbin already has a global
WARNS=6 setting in HEAD (unlike stable/8), so it's best
to remove the line entirely.

syslogd(8) already supports *sending* log messages to non-
standard ports, but it can't *receive* them (port 514 is
hardcoded). This commit adds that missing feature.

(NB: I actually needed this feature for a server farm where
multiple jails run with shared IP addresses, and every jail
should have its own syslogd process.)

As a side effect, syslogd now compiles with WARNS=6.

Port all applications in usr.sbin/ from libulog to utmpx.

Let syslogd use utmpx.

Because strings are guaranteed to be null terminated, there is no need
for excessive copying of strings, such as the line name.

Rather than hardcode the 'struct iovec iov' array size, use a #define.
While I'm here bump WARNS to 3.

Obey MK_INET6_SUPPORT.

Fixed style of DPADD and LDADD assignments as per style.Makefile(5).

Avoid code duplication by using libutil's trimdomain() instead of
an incorrect re-implementation.

style.Makefile(5)

Use CFLAGS instead of COPTS.

- Silence warnings: apply `const' generously, mark some variables
__unused, and change local variables named `sin' (struct
sockaddr_in) to `sin4'. (`sin' conflicts with the definition of
sin(3), which gcc assumes to be defined even if math.h isn't
included (it's a builtin). This is probably a bug in gcc.)

- Apply WARNS=1. WARNS=2 was not used because this program assigns
string literals to (struct iovec).iov_base for writing, and the only
clean way to silence -Wwrite-strings in that case would be to
strdup() and consequently free() those literals, which I considered
too disruptive.

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.
