introduce namespace-safe rwlock aliases; use in pthread_key_create

commit 84d061d5a31c9c773e29e1e2b1ffe8cb9557bc58 inadvertently
introduced namespace violations by using the pthread-namespace rwlock
functions in pthread_key_create, which is in turn used for C11 tss.
fix that and possible future uses of rwlocks elsewhere.
