gdb: move a bunch of quit-related things to event-top.{c,h}

Move some declarations related to the "quit" machinery from defs.h to
event-top.h.  Most of the definitions associated to these declarations
are in event-top.c.  The exceptions are `quit()` and `maybe_quit()`,
that are defined in utils.c.  For consistency, move these two
definitions to event-top.c.

Include "event-top.h" in many files that use these things.
