Brush up previous, or make things more similar to x86:

- Prevent pic_name from appearing vmstat(1) twice.
- Restore "irq" in interrupt id fields of intrctl(8).

For these purposes,

- Add is_evname member to struct intr_source.
- Bump size of is_source to INTRIDBUF, and rename it to is_intrid for clarity.

Now, outputs from vmstat(1) and intrctl(8) are like:

----
$ vmstat -ev
...
openpic irq 39 3967 26 intr
...
$ intrctl list
interrupt id CPU0 device name(s)
...
openpic irq 39 3967* wdc1
...
----

The reasoning turned out to be wrong; __KERNEL_RCSID() in header files
does *not* overwrite RCSID in main source files. The real problem is that
it inserts its RCSID into *every* object files. However, it can be still
useful even if heavily duplicated.

Stop using __KERNEL_RCSID() in header files; it confuses ident(1) by
overwriting RCSID in main source files.

XXX
The first argument of __KERNEL_RCSID() is neglected for ELF. If we wish
to have RCSID of header files in kernel binary, we need something like
__FBSDID() macro in FreeBSD.

branches: 1.10.12;
use 128 as IPI_VECTOR to avoid overlap wth hardware interrupts

branches: 1.9.52;
Use <sys/foo.h> instead of <machine/foo.h> if such a file exists.
Don't assume <sys/cpu.h> includes <powerpc/subarch/cpu*.h>. Include it
explicitly.

Change from level to ipl since we aren't dealing a mask anymore, just a
simple value.
Fix intr_calculatemasks to deal with ipl isn't a mask. Let establish
and disestablish determine the highest ipl for the interrut source being
modified. No reason to recompute that for every source when only one changes
at a time. Only change idepth while in the loop.

branches: 1.7.6;
Support 64-bit imask for powerpc/pic.

branches: 1.6.2; 1.6.4;
- Have pic_mpcsoc.c to adapt variations of Moto/Freescale OpenPIC
compliant interrupt controllers. Mostly the refrain of pic_openpic.c
and shall be useful for 85xx/86xx/QorIQ and Tundra product lines.

Add support to ofppc for the IBM 7044-270 machine. This is a POWER3-II
based machine. Currently the kernel to run on this machine is
incompatible with the standard GENERIC kernel, so for now, we have a
separate GENERIC_B64. Eventually, I hope to combine the two.

Please note, this is a port of 32bit ofppc, not a powerpc64 port.

Thanks to Matt Thomas and Kevin Bowling for helping to make this port
possible.

Summary of changes:

Change ofwpci to use the ofmethod config for configuring the PCI bus,
rather than indirect configuration.
Move the wiring of the interrupt controllers from at the start of the
boot, into the configuration of the first PCI bus.
Rewrite the map_isa_ioregs() hack to work on a machine without BATs
Fix a ton of bugs in the genofw_find_pics routine, and in the map_space code.
Split the pic_openpic into openpic_common and pic_openpic.
Create a new pic_distopenpic driver, for the distributed openpic found on
some newer IBM machines.
Fix a bad panic in pmap_extract on 64bit bridge mode

Fix the endless stream of 7's problem on i8259-like interrupt controllers
once and for all. The i8259 does not like to be read in a loop, when an
interrupt comes in, it will return a valid value, however, if you keep
reading it until there are no outstanding interrupts, it will return 7
(which is the lpt interrupt). Change the pic handler to give an argument
to the get_irq functions of mode, which indicates if this is the first
time we are asking, or if we are just rechecking in a loop. Non-i8259
handlers can safely ignore this argument.

Tested to fix the stream of 7's problem on prep and ofppc. Got rid of
the nasty hack in ofppc with this too, and the prep machine seems to take
less interrupts now, which is a good thing.

Merge the ppcoea-renovation branch to HEAD.

This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree. Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches. The work
for this branch was done by a variety of people, too long to list here.

TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.

NOTES:
pmppc was removed as an arch, and moved to a evbppc target.

branches: 1.1.2; 1.1.6; 1.1.8;
file picvar.h was initially added on branch ppcoea-renovation.
