Restructure the IPI code a little, allowing multiple IPIs to be sent at
...
once. Add a way to broadcast an IPI to all processors (except the sender,
obviously). Add an IPI for TLB shootdown.

Add basic interprocessor interrupt sending and receiving code. Current
...
IPI functions: HALT, IMB, TBIA, TBIAP.
XXX HALT is not yet implemented, it's just a stub.

Implement alpha_shared_intr_disestablish(). Simply removes the handler

fromthe list, allowing the caller to manipulate the sharing type,
if appropriate.

Switching dev/ic/lpt.c to use spllpt() instead of spltty(). It doesn't use
...
tty structures, and on some machines (namely the DraCo internal lpt, and some
multi-i/o boards for Amigas and DraCos), tying spltty to the pretty high printer
interupt level would hurt serial performance.
On all affected ports but Amiga, spllpt() has been defined in machine/intr.h
to be spltty(), thus preserving old behaviour. Portmasters are encouraged to
change is, if they feel something else is better (e.g., one of its own were
possible).

mark prototypes for static inline functions as possibly unused

compiling without optimization but with the default warning flags.

actually, declare _splraise() as an inline function, because:
...
(1) it was using 'max', and some functions use a variable
of that name (*sigh*), and
(2) that makes it easier to be a bit trickier, and only call
swpipl if changing the IPL.

make sure that splnet(), splbio(), splimp(), spltty(), splclock(),

splstatclock(), and splhigh() all _raise_ the IPL. (splhigh() is _not_
the highest possible IPL; mcheck is...)
