* cygheap.cc (cygheap_init): Fix formatting. Remove comment. Set

	shared_prefix depending only on terminal service capability.
	* dcrt0.cc (dll_crt0_1): Don't call set_cygwin_privileges here.
	* fhandler_fifo.cc (fhandler_fifo::open): Create the mutex as global
	object.
	* posix_ipc.cc (ipc_mutex_init): Use cygheap->shared_prefix.
	(ipc_cond_init): Ditto.
	* sec_helper.cc (privilege_name): Make static.  Use LookupPrivilegeName
	directly to be independent of the state of cygheap.
	(set_privilege): Take a LUID as parameter instead of an index value.
	Only print debug output in case of failure.
	(set_cygwin_privileges): Add comment.  Use LookupPrivilegeValue to
	get privilege LUIDs.
	(init_global_security): Call set_cygwin_privileges here.
	* security.h (privilege_name): Drop declaration.
	(set_privilege): Declare according to above change.
	(set_process_privilege): Call privilege_luid to get LUID.
	(_push_thread_privilege): Ditto.
	* shared.cc (open_shared): Add comment.  On systems supporting the
	SeCreateGlobalPrivilege, try to create/open global shared memory first.
	Fall back to local shared memory if that fails.
	* thread.cc (semaphore::semaphore): Use cygheap->shared_prefix.
	* wincap.h (wincapc::has_create_global_privilege): New element.
	* wincap.cc: Implement above element throughout.
