Check small set and reject it, this is how kernel did. Always use the
...
size kernel is using.

...
- Use long word to figure out sizeof kernel cpuset, hope it works.

Avoid various shadowed variables. libthr is now almost WARNS=4 clean except
...
for some const dequalifiers that needs more careful investigation.

- 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.

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.

- 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.
