signals instead of having more intricate knowledge of thread state
within signal handling.
Simplify signal code because of above (by David Xu).
Use macros for libpthread usage of pthread_cleanup_push() and
pthread_cleanup_pop(). This removes some instances of malloc()
and free() from the semaphore and pthread_once() implementations.
When single threaded and forking(), make sure that the current
thread's signal mask is inherited by the forked thread.
Use private mutexes for libc and libpthread. Signals are
deferred while threads hold private mutexes. This fix also
breaks www/linuxpluginwrapper; a patch that fixes it is at
http://people.freebsd.org/~deischen/kse/linuxpluginwrapper.diff
Fix race condition in condition variables where handling a
signal (pthread_kill() or kill()) may not see a wakeup
(pthread_cond_signal() or pthread_cond_broadcast()).

Move it, and update to match SUS. Leave the prototype in string.h for

ID ranges that consist of exactly one attribute ID. libsdp(3) will check start
and end of the attribute ID range and if they are the same the range will be
collapsed to one atribute ID.
The problem was observed on Audiovox SMT5600 and Palm Treo 650.

This avoids an arithmetic exception when dividing LONG_MIN by 1:
This is the only case that causes overflow, and the resulting value
is correct under 2's compliment arithmetic.
