refactor(sleep): simplify rube goldberg implementation of :sleep

Browse Source 
As neovim does have event handling, we are checking for CTRL-C
all the time, not once per second.

Also, do_sleep() reimplements the same loop as
LOOP_PROCESS_EVENTS_UNTIL() already contains internally. Fix the latter
to use the right integer type, so we do not need the extra indirection.
