b529e734cb Cleanup of xlocale:
- Address performance regressions encountered by das@ by caching per-thread
  data in TLS where available.
- 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.

Ignore the NAT_T extension types so we can at least dump the SADB from

However in case there is no NAT_T support in kernel still consider them

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
overwritten entries. To solve this, make sure we always read a multiple

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.

bd849a2aad Try to avoid ambiguity when sysctl returns ENOMEM additionally
checking the returned oldlen: when ENOMEM is due to the supplied
buffer being too short the return oldlen is equal to buffer size.

Without this additional check kvm_getprocs() gets stuck in loop if the
returned ENOMEM was due the exceeded memorylocked limit. This is
easily can be observed running `limits -l 1k top'.

cec8421d47 This commit adds profiling support for powerpc64. Now we can do application
profiling and kernel profiling. To enable kernel profiling one has to build
kgmon(8). I will enable the build once I managed to build and test powerpc
(32-bit) kernels with profiling support.

- add a powerpc64 PROF_PROLOGUE for _mcount.
- add macros to avoid adding the PROF_PROLOGUE in certain assembly entries.
- apply these macros where needed.
- add size information to the MCOUNT function.

0628630580 Don't inline fenv.h functions on arm for now. Inlining makes sense:
the function bodies require only 2 to 10 instructions.  However, it
leads to application binaries that refer to a private ABI, namely, the
softfloat innards in libc.  This could complicate future changes in
the implementation of the floating-point emulation layer, so it seems
best to have programs refer to the official fe* entry points in libm.

e5fa065e08 Rev 228065 (change bsd.own.mk -> bsd.init.mk) broke pam_unix.so by causing
the LDADD/DPADD to lose the -lpam, and causing openpam_dynamic() to fail
due to "openpam_get_options" being undefined.

This would cause obscure console log messages like:
  openpam_dynamic(): No error: 0
  openpam_load_module(): no pam_unix.so found
and other helpful messages which are no help in diagnosing the problem.

Fortunately this change was not mfc'ed to 9.x, it isn't broken there.
