* create.c (pthread_create): Add priority inheritance
attributes.
* mutex.c (pthread_mutex_lock): Remove some overhead for
PTHREAD_MUTEX_NORMAL mutex types. Specifically, avoid
calling pthread_self() and pthread_equal() to check/set
the mutex owner. Introduce a new pseudo owner for this
type. Test results suggest increases in speed of up to
90% for non-blocking locks.
This is the default type of mutex used internally by other
synchronising objects, ie. condition variables and
read-write locks. The test rwlock7.c shows about a
30-35% speed increase over snapshot 2001-06-06. The
price of this is that the application developer
must ensure correct behaviour, or explicitly set the
mutex to a safer type such as PTHREAD_MUTEX_ERRORCHECK.
For example, PTHREAD_MUTEX_NORMAL (or PTHREAD_MUTEX_DEFAULT)
type mutexes will not return an error if a thread which is not
the owner calls pthread_mutex_unlock. The call will succeed
in unlocking the mutex if it is currently locked, but a
subsequent unlock by the true owner will then fail with EPERM.
This is however consistent with some other implementations.
(pthread_mutex_unlock): Likewise.
(pthread_mutex_trylock): Likewise.
(pthread_mutex_destroy): Likewise.
* attr.c (pthread_attr_init): PTHREAD_EXPLICIT_SCHED is the
default inheritance attribute; THREAD_PRIORITY_NORMAL is
the default priority for new threads.
* sched.c (pthread_attr_setschedpolicy): Added routine.
(pthread_attr_getschedpolicy): Added routine.
(pthread_attr_setinheritsched): Added routine.
(pthread_attr_getinheritsched): Added routine.
* pthread.h (sched_rr_set_interval): Added as a macro;
returns -1 with errno set to ENOSYS.

*sched.c (pthread_attr_setschedparam): Add priority range
check.
(sched_setscheduler): New function; checks for a valid
pid and policy; checks for permission to set information
in the target process; expects pid to be a Win32 process ID,
not a process handle; the only scheduler policy allowed is
SCHED_OTHER.
(sched_getscheduler): Likewise, but checks for permission
to query.
* pthread.h (SCHED_*): Moved to sched.h as defined in the
POSIX standard.
* sched.h (SCHED_*): Moved from pthread.h.
(pid_t): Defined if necessary.
(sched_setscheduler): Defined.
(sched_getscheduler): Defined.
* pthread.def (sched_setscheduler): Exported.
(sched_getscheduler): Likewise.

* create.c (pthread_create): Set thread priority from
thread attributes.
