[COMMITTED PATCH] NPTL: Add stubs for Linux-only extension functions.

[Roland McGrath <roland at hack dot frob dot com>]

These four are nonstandard functions for which the only implementations
are pure Linuxism.  I've added ENOSYS stubs that are OS-generic.  The
getname/setname interface could be implemented "generically" to just
store and fetch the name locally, but that is probably not of much use.


Thanks,
Roland
