0d1f91e8e1 Define several extra macros in bsd.sys.mk and sys/conf/kern.pre.mk, to
get rid of testing explicitly for clang (using ${CC:T:Mclang}) in
individual Makefiles.

Instead, use the following extra macros, for use with clang:
- NO_WERROR.clang       (disables -Werror)
- NO_WCAST_ALIGN.clang  (disables -Wcast-align)
- NO_WFORMAT.clang	(disables -Wformat and friends)
- CLANG_NO_IAS		(disables integrated assembler)
- CLANG_OPT_SMALL	(adds flags for extra small size optimizations)

As a side effect, this enables setting CC/CXX/CPP in src.conf instead of
make.conf!  For clang, use the following:

CC=clang
CXX=clang++
CPP=clang-cpp

6132589d7b Update libarchive to 3.0.3
Some of new features:
  - New readers: RAR, LHA/LZH, CAB reader, 7-Zip
  - New writers: ISO9660, XAR
  - Improvements to many formats, especially including ISO9660 and Zip
  - Stackable write filters to write, e.g., tar.gz.uu in a single pass
  - Exploit seekable input; new "seekable" Zip reader can exploit the Zip
    Central Directory when it's available; the old "streamable" Zip reader
    is still fully supported for cases where seeking is not possible.

61033245ae In revision 231989, we pass a 16-bit clock ID into kernel, however
according to POSIX document, the clock ID may be dynamically allocated,
it unlikely will be in 64K forever. To make it future compatible, we
pack all timeout information into a new structure called _umtx_time, and
use fourth argument as a size indication, a zero means it is old code
using timespec as timeout value, but the new structure also includes flags
and a clock ID, so the size argument is different than before, and it is
non-zero. With this change, it is possible that a thread can sleep
on any supported clock, though current kernel code does not have such a
POSIX clock driver system.

d177303078 Use unused fourth argument of umtx_op to pass flags to kernel for operation
UMTX_OP_WAIT. Upper 16bits is enough to hold a clock id, and lower

from libthr.

b529e734cb Cleanup of xlocale:
- Address performance regressions encountered by das@ by caching per-thread

- Add a __NO_TLS flag to cdefs.h to indicate where not available.
- Reorganise the xlocale.h definitions into xlocale/*.h so that they can be
  included from multiple places.
- Export the POSIX2008 subset of xlocale when POSIX2008 says it should be
  exported, independently of whether xlocale.h is included.
- Fix the bug where programs using ctype functions always assumed ASCII unless
  recompiled.
- Fix some style(9) violations.

23524b572c Globally replace u_int*_t from (non-contributed) man pages.
The reasoning behind this, is that if we are consistent in our
documentation about the uint*_t stuff, people will be less tempted to
write new code that uses the non-standard types.

I am not going to bump the man page dates, as these changes can be
considered style nits. The meaning of the man pages is unaffected.

6d383df7bb Replace utxrm(8) by utx(8).
At first, I added a utility called utxrm(8) to remove stale entries from
the user accounting database. It seems there are cases in which we need
to perform different operations on the database as well. Simply rename
utxrm(8) to utx(8) and place the old code under the "rm" command.

In addition to "rm", this tool supports "boot" and "shutdown", which are
going to be used by an rc-script which I am going to commit separately.

aa3326a535 Set read buffer size to multiple of sizeof(struct futx).
If the utmpx database gets updated while an application is reading it,
there is a chance the reading application processes partially

891142ea87 Switch getifaddrs(3) to the new API introduced in r231505. Also remove
conditional code parts not used by or applicable to FreeBSD.

The new implementation is supposed to be able to cope with changes to
the 'l' versions of the msghdr structs now used as well as to if_data
allowing future changes without breaking things.

This restores carp(4) config support in HEAD after r231504.

10fb6673e8 Using the O_CLOEXEC flag on open(2) caused the pidfile lock to be lost
when the child process execs daemon's target program thanks to flock(2)
semantics. So, we apparently have to leak the open pidfile's file
descriptor to keep the lock for the pidfile(3) functions to work properly.
