* sysdeps/pthread/timer_getoverr.c: Return real overrun.
* sysdeps/pthread/posix-timer.h (struct timer_node): Add overrun_count.
* sysdeps/pthread/timer_routines.c (thread_func): Schedule next timeout
based on previous one and not on current time. Count overruns.
Patch by Eric F. Sorton <eric@cctcorp.com>.
* sysdeps/unix/sysv/linux/bits/local_lim.h: Add DELAYTIMER_MAX.
(FLOATING_STACKS, ARCH_STACK_MAX_SIZE): Defined.
* iconv/gconv_int.h (strict gconv_module): Remove all members
associated with regular expressions. Use a simple string as the
from name.
* iconv/gconv_db.c: Remove code handling regular expressions.
* iconv/gconv_conf.c: Likewise.
* iconv/iconv_prog.c: Likewise.
* iconv/gconv_builtin.h: Adjust for change in gconv_conf.c.

A few optimizations. Got rid of unnecessary wakeups of timer threads,
tightened up some critical regions and micro-optimized some list
manipulation code.
* sysdeps/pthread/timer_routines.c (__timer_thread_queue_timer):
Returns int value now to indicate whether timer was queued at head.
* sysdeps/pthread/posix-timer.h: Likewise.
* sysdeps/pthread/timer_settime.c (timer_settime): Takes advantage of
new return value from __timer_thread_queue_timer to avoid waking
up timer thread unnecessarily.
* sysdeps/pthread/posix-timer.h (timer_id2ptr): No longer checks
inuse flag, because this requires mutex to be held. Callers updated
to do the check when they have the mutex.
* sysdeps/pthread/timer_getoverr.c: Add check for inuse here.
* sysdeps/pthread/timer_settime.c (timer_settime): Tighter critical
regions: avoids making system calls while holding timer mutex, and
a few computations were moved outside of the mutex as well.
* sysdeps/pthread/timer_gettime.c (timer_gettime): Likewise.
* sysdeps/pthread/posix-timer.h (list_unlink_ip): Function name changed
to list_unlink_ip, meaning idempotent. Pointer manipulation
changed to get better better code out of gcc.
* sysdeps/pthread/timer_routines.c (list_unlink): Non-idempotent
version of list_unlink added here.
* sysdeps/pthread/timer_delete.c: Use appropriate list unlink
function in all places: idempotent one for timers, non-idempotent
one for thread nodes.
* sysdeps/pthread/timer_settime: Likewise.
* sysdeps/pthread/timer_routines.c: Likewise.

* sysdeps/pthread/timer_create.c: Thread matching now done on
clock type as well as thread attributes.
There are individual global signal-delivering threads for
different clock types.
* sysdeps/pthread/posix-timer.h: Likewise.
* sysdeps/pthread/timer_routines.c: Likewise.
* sysdeps/pthread/timer_routines.c: Thread allocation and
deallocation function now remembers to put thread on active
list and remove from active list.
Thus now the feature of binding multiple timers
to a single thread actually works.
* sysdeps/pthread/posix-timer.h (struct timer_node): Add creator_pid.
* sysdeps/pthread/timer_create.c: Fill in creator_pid.
* sysdeps/pthread/timer_routines.c (thread_expire_timer): Send signal
with sigqueueinfo is this system call is available.
* sysdeps/pthread/timer_create.c (timer_create): Allow
CLOCK_CPUTIME if _POSIX_CPUTIME is defined.
