* defs.h: Fix cntl-C to read from the Windows message queue.

	Add prototypes for make_final_cleanup (and the other cleanup
	routines.
	* remote-e7000.c: Fix sync code to timeout if unable to sync.
	Change sync code to report status while trying to sync-up
	with hardware.  Add debugging output and document.
	* ser-e7kpc.c: Swap order of len & offset to match implementation.
	Add debugging output and document.
	* serial.c: Add debugging output.
	* top.c: Add call to do_final_cleanups.
	Remove conditionals preventing Win32 from getting SIGQUIT.
	* utils.c: (*_cleanup): Modify cleanup routines to accept a cleanup
	chain as a parameter.  Extract this generic code from the cleanup
	routines into separate funtions (*_my_cleanup).  Keep old
	functionality by passing "cleanup_chain" to the new funtions.
	Define the cleanup chain "final_cleanup_chain" to be a cleanup
	chain which will be executed only when gdb exits.  Add functions
	(*_final_cleanup) to match the original (*_cleanup) functions.
	(pollquit, quit, notice_quit): Fix to read cntl-C from the
	Windows message queue.
