* keyboard.c (record_asynch_buffer_change): Initialize an event

only if it's really needed.
* frame.h (enum output_method): Remove output_mac member since
it's a leftover from the deleted code.
* frame.c (Fframep): Adjust user here ...
* terminal.c (Fterminal_live_p): ... and here.
* coding.c (Qmac): Now here because it's only used to denote
end-of-line encoding type.
(syms_of_coding): DEFSYM it.
* frame.h (Qmac): Remove duplicated declaration.
