lib/libthr/arch/amd64/amd64 _umtx_op_err.S
lib/libthr/arch/i386/i386 _umtx_op_err.S
Log:
MFC:
- add _umtx_op_err function to improve stability because of errno
changed by application signal handler code.
- use kernel based userland rwlock to implement pthread_rwlock,
improve performance in most cases.
