sysinst/partitions.h: fix typos comments, also fix same typos in other files.

Use the default implementations of attach_hook(), bus_maxdevs(),
make_tag(), and decompose_tag().

Liberally sprinkle static around to get more symbols out of the
global namespace. A small bit of const poisoning in the TC code.

PCI Extended Configuration stuff written by nonaka@:
- Add PCI Extended Configuration Space support into x86.

Currently the following extended capabilities are decoded:
- Advanced Error Reporting
- Virtual Channel
- Device Serial Number
- Power Budgeting
- Root Complex Link Declaration
- Root Complex Event Collector Association

Split up using BWX for PCI config and bus access. Default to using BWX for
the former, but not the latter. Hopefully, this will address some problems
people have been experiencing w/ some devices on Pyxis systems when BWX
is used for bus access. (If it's not used for PCI config access, we can
get fatal machine checks while probing behind PCI-PCI bridges!!)

Add support for using BWX for PCI config space and PCI i/o and mem space
on the ALCOR2 and Pyxis. BWX is enabled iff:
- It hasn't been disabled by the user (patch `cia_use_bwx' or build cia.o
with the option "CIA_USE_BWX=0"),
- it's enabled in CIA_CSR_CNFG,
- we are running on an EV5-family processor,
- BWX is in the processor's capabilities mask.

Gah, typo.

Oops, and the writes, too.

Clean up the code that puts the PCI controller into config mode 1; no
functional difference.

Make compile without DIAGNOSTIC set.

In addition to MAS_ABT, check TAR_ABT when doing configuration space
reads. This is necessary because of newer AlphaStation firmware doing
the Wrong Thing with target aborts behind PCI-PCI bridges, much like they
do the Wrong Thing with master aborts. Reported by Matthias Drochner.

Make sure to clear MAS_ABT if we received one.

branches: 1.15.2;
Use the symbolic name for "received master abort".

Apparently, new AlphaStation 500/600 firmware has the same problem with
PCI master aborts as eb164 firmware, so use the same workaround mechanism
on all system types (clear error register's master abort bit, and check
it after accessing configuration space), not just eb164's.

This also fixes a bug on eb164's - when making the Alpha port compile
again, I made an error that caused this to not be used on eb164 systems,
either. Thanks to Matt Jacob for pointing out this goof.

Apply a change made to other PCI chipsets:
don't expect/provide pci_decompose_tag to be a MI, public function. It
wasn't intended to be to begin with, and uses of it (e.g. the one in the
'de' driver) are quite likely to be incorrect.

Nuke the idea of <machine/options.h>. It completely defeats the purpose
of fine-grain option dependencies.

by default, provide RCS IDs for NetBSD/alpha kernel files in kernel binaries.
This can be disabled (to save a bit of space) with the NO_KERNEL_RCSIDS
options, which is present but commented out in the ALPHA config file.
In ELF-format kernels, these strings are present in the kernel binary but
are not loaded into memory. (In ECOFF-format kernels, there's no easy way
to keep them from being loaded, so they _are_ loaded into memory.)

when machine checks are posted while examining nonexistant devices.
