there's a MP-safe interrupt handling structure); until then, it should
be used when MULTIPROCESSOR and IPL_SERIAL > IPL_SCHED.

Add options DDB_BREAK_CHAR. This overrides break on the serial console

break character with the supplied one. This is useful for cases where
break is hard to generate, or you are connected to a PC that "sends"
breaks when power cycled. For this mode in com, interpret break char
in the polling section, which allows entry into the debugger before
the tty is opened. Only supported in the com driver currently.

New callout mechanism with two major improvements over the old
...
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
resource allocation.
- Insertion and removal of callouts is constant time, important as
this facility is used quite a lot in the kernel.
The old timeout()/untimeout() API has been removed from the kernel.
