Follow the mistake in libpthread, the first version name in libpthread
is LIBTHREAD_1_0, but really it should be LIBPTHREAD_1_0.
Fix it so libmap.conf works again (it was broken by recent versioning
code in rtld_elf).

Add code to handle timer_delete(). The timer wrapper code is completely
rewritten, now timers created with same sigev_notify_attributes will
run in same thread, this allows user to organize which timers can
run in same thread to save some thread resource.

Add timer_create wrapper.

Put pthread_condattr_init sorted order.

Export following functions:
_pthread_mutexattr_getpshared
_pthread_mutexattr_setpshared
pthread_condattr_getpshared
pthread_condattr_setpshared
pthread_mutexattr_getpshared
pthread_mutexattr_se

Sort function names.

Add function pthread_timedjoin_np, the function is similar with pthread_join
except the function will return ETIMEDOUT if target thread does not exit
before specified absolute time passes.

Add usleep to the map files.

Add debugger event reporting support, current only TD_CREATE and TD_DEATH
events are reported.

Export pthread_condattr_getclock, pthread_condattr_setclock.

Import my recent 1:1 threading working. some features improved includes:
1. fast simple type mutex.
2. __thread tls works.
3. asynchronous cancellation works ( using signal ).
4. thread synchronization is fully based on umtx, mainly, condition
variable and other synchronization objects were rewritten by using
umtx directly. those objects can be shared between processes via
shared memory, it has to change ABI which does not happen yet.
5. default stack size is increased to 1M on 32 bits platform, 2M for
64 bits platform.
As the result, some mysql super-smack benchmarks show performance is
improved massivly.
