(xrm_get_preference_database): Remove BLOCK_INPUT.

[TARGET_API_MAC_CARBON] (cfdate_to_lisp): Obtain microsec value.
Use kCFAbsoluteTimeIntervalSince1970.
(wakeup_from_rne_enabled_p) [MAC_OSX]: Remove variable.
(ENABLE_WAKEUP_FROM_RNE, DISABLE_WAKEUP_FROM_RNE) [MAC_OSX]:
Remove macros.
[MAC_OSX] (socket_callback): Do nothing.
[MAC_OSX] (select_and_poll_event): Use CFRunLoopRunInMode instead of
ReceiveNextEvent.
[MAC_OSX] (sys_select): Likewise.  Don't set context as argument to
socket_callback.
(mac_wakeup_from_rne) [MAC_OSX]: Do nothing.
