New module to hold the alpha-specific prototypes that don't need to be
...
exported to the MI kernel. Almost everything here was formerly in cpu.h.
Optionally, this module could in the future be used to #include anything
that is always needed by arch/alpha modules.

Rip out 70 lines of (all of) the port-alpha-specific decls and prototypes.
...
They should not be visible to the MI kernel and the MI kernel shouldn't
depend on this junk. Most of it moves to new module <machine/alpha.h>.
Leave badaddr() here, though, because it's used so widely.

Nuke the giant ugly-as-sin per-platform INTRNAMES masterpiece.
...
I just cannot add one more platform without getting sick.
Instead, we do just one table for all platforms. More-or-less,
it was only the A12 that even named it's individual interrupts anyway.
Also, prototype set_iointr() here. It's a slightly odd place, but 10*
better than the old place it was, and this file is included by exactly
the perfect set of .c files for set_iointr() visibility.

Changes to support fork_kthread():
...
- cpu_set_kpc() now takes void *arg third argument, passed to the
entry point.
- cpu_fork() allows parent to be non-curproc iff parent is proc0.
When forking non-curproc, assume its state has already been saved.
- Adjust various pieces of machine-dependent code to account of all of this.

bus_space(9), if drivers want it (they shouldn't; easy to convert) they

the interfaces were (slightly) changed, and no code in the source tree
uses the old interfaces as far as I can tell.

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).
