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.
