Caching scheduling policy and priority in userland, a critical but baddly

written application is frequently changing thread priority for SCHED_OTHER
policy.

Use thr_setscheduler, thr_getscheduler and thr_setschedparam to implement

pthread functions.

Use kernel facilities to support real-time scheduling.

- Use same priority range returned by kernel's sched_get_priority_min()

  and sched_get_priority_max() syscalls.
- Remove unused fields from structure pthread_attr.

WARNS level 4 cleanup.

Import my recent 1:1 threading working. some features improved includes:

2005-04-02T01:20:00+00:00

 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.

o Catch up with the mutex priority protocol fixes.

o Move pthread_getschedparam() into the same file with it's
  pthread_set* counterpart. Copyright on both files is identical.

- Add libthr but don't hook it up to the regular build yet. This is an

   adaptation of libc_r for the thr system call interface.  This is beta
   quality code.
