Summary: Provide Robust pthread_rwlock_t modifiers
Description:
A wart with rwlocks at the moment is that rwlocks can be cross process like
pthread_mutex_t but not robust, unlike pthread_mutex_t.

This issue seeks to rectify the situation to provide cross process robust
rwlocks.


This is my first issue raised to this tracker - I tried to join the austin
group mailing list for discussion there but the registration site is having
some issues creating new individuals.
Desired Action:
provide the following apis and cloned behavior of robust mutex's:

int pthread_rwlockattr_getrobust(const pthread_rwlockattr_t *restrict
attr, int *restrict robust);
int pthread_rwlockattr_setrobust(pthread_rwlockattr_t *attr,
int robust)

Operations on rwlocks owned by dead processes should return the error
EOWNERDEAD, like robust mutexes.
