97576c1c61 Convert a couple of hardcoded values to constants. Make thr_getcontext()
return 0 when called the first time, and return 1 when resumed by
thr_setcontext().

ed74e02776 Relink libc_r.a, libc_r.so and libc_r_p.so from libthr to libkse.
On ia64, where there's no libc_r at all, libkse is now the default
thread library by virtue of these links.

The reasons for this change are:
1. libkse is slated to become the default thread library anyway,
2. active development and maintenance is only present for libkse,
3. GNOME and KDE, both in the process of being supported on ia64,
   work better with KSE; even on ia64.

f9657fb6bf Disable #define DEBUG in libdisk by default: since libdisk is primarily
there to support sysinstall, and enabling DEBUG creates spurious
console output that can't be read anyway...  This slightly cleans up
the visual impression of the system install by not spamming the console
during the labeling of the disks.

ee9003796a Fix fabs(). This commit brought to you by the letter 'l'.
(fstp stores a mem32 value, fstpl stores a mem64 value)

This fixes ghostscript for 'make release' on amd64.  Ghostscript for some
reason thinks it is a good idea to use -fno-builtin, which means it is
vulnerable to bugs in libc that are normally hidden by the builtin gcc
functions.  Oops.

3d10572d1a As comments in _mutex_lock_backout state, only current thread
can clear the pointer to mutex, not the thread doing mutex
handoff. Because _mutex_lock_backout does not hold scheduler
lock while testing THR_FLAGS_IN_SYNCQ and then reading mutex
pointer, it is possible mutex owner begin to unlock and
handoff the mutex to the current thread, and mutex pointer
will be cleared to NULL before current thread reading it, so
current thread will end up with deferencing a NULL pointer,
Fix the race by making mutex waiters to clear their mutex pointers.
While I am here, also save inherited priority in mutex for
PTHREAD_PRIO_INERIT mutex in mutex_trylock_common just like what
we did in mutex_lock_common.

b07fbc17e9 Add Cisco Skinny Station protocol support to libalias, natd, and ppp.
Skinny is the protocol used by Cisco IP phones to talk to Cisco Call
Managers.  With this code, one can use a Cisco IP phone behind a FreeBSD
NAT gateway.

Currently, having the Call Manager behind the NAT gateway is not supported.
More information on enabling Skinny support in libalias, natd, and ppp
can be found in those applications' manpages.

302e193264 Make KSE_STACKSIZE machine dependent by moving it from thr_kern.c to
pthread_md.h. This commit only moves the definition; it does not
change it for any of the platforms. This more easily allows 64-bit
architectures (in particular) to pick a slightly larger stack size.

aec40a4c57 _ia64_break_setcontext() now takes a mcontext_t. While here, define
THR_SETCONTEXT as PANIC(). The THR_SETCONTEXT macro is currently not
used, which means that the definition we had could be wrong, overly
pessimistic or unknowingly right. I don't like the odds...

The new _ia64_break_setcontext() and corresponding kernel fixes make
KSE mostly usable. There's still a case where we don't properly
restore a context and end up with a NaT consumption fault (typically
an indication for not handling NaT collection points correctly),
but at least now mutex_d works...

a87a12715c Remove a comment that questioned why the size of the FPU
state for amd64 was twice as large as necessary.  Peter
recently fixed this, so the comment no longer applies.

Also, since the size of struct mcontext changed, adjust
the threads library version of get&set context to match.

FYI, any change layout/size change to any arch's struct
mcontext will likely need some minor changes in libpthread.
