- Copy stable/10 (r259064) to releng/10.0 as part of the
10.0-RELEASE cycle.
- Update __FreeBSD_version [1]
- Set branch name to -RC1

[1] 10.0-CURRENT __FreeBSD_version value ended at '55', so
start releng/10.0 at '100' so the branch is started with
a value ending in zero.

Make ofw_bus_get_node() consistently return -1 when there is no associated
OF node, instead of a random mixture of 0 and -1. Update all checks for 0
to check for -1 instead.

Inherit from PCI bridge driver instead of manually specifying all of its
methods.

- There's no need to overwrite the default device method with the default
one. Interestingly, these are actually the default for quite some time
(bus_generic_driver_added(9) since r52045 and bus_generic_print_child(9)
since r52045) but even recently added device drivers do this unnecessarily.
Discussed with: jhb, marcel
- While at it, use DEVMETHOD_END.

Rename INTR_VEC to MAP_IRQ. From the OFW or FDT we obtain a
PIC handle with interrupt pin. This we map to the resource
called SYS_RES_IRQ.

Add MSI support for PCI devices attached to the CPC925 and CPC945 bridges
found in Apple and IBM G5 systems.

Provide for multiple, cascaded PICs on PowerPC systems, and extend the
OFW interrupt map interface to also return the device's interrupt parent.

Adapt parts of the sparc64 Open Firmware bus enumeration code (in particular,
the code for parsing interrupt maps) to PowerPC and reflect their new MI
status by moving them to the shared dev/ofw directory.

This commit also modifies the OFW PCI enumeration procedure on PowerPC to
allow the bus to find non-firmware-enumerated devices that Apple likes to add,
and adds some useful Open Firmware properties (compat and name) to the pnpinfo
string of children on OFW SBus, EBus, PCI, and MacIO links. Because of the
change to PCI enumeration on PowerPC, X has started working again on PPC
machines with Grackle hostbridges.

Convert PowerPC AIM PCI and nexus busses to standard OFW bus interface. This
simplifies certain device attachments (Kauai ATA, for instance), and makes
possible others on new hardware.

On G5 systems, there are several otherwise standard PCI devices
(Serverworks SATA) that will not allow their interrupt properties to be
written, so this information must be supplied directly from Open Firmware.

- Make pcib_devclass private to sys/dev/pci/pci_pci.c and change all the
various pcib drivers to use their own private devclass_t variables for
their modules.
- Use the DEFINE_CLASS_0() macro to declare drivers for the various pcib
drivers while I'm here.

Instead of "OpenFirmware", "openfirmware", etc. use the official spelling
"Open Firmware" from IEEE 1275 and OpenFirmware.org (no pun intended).

Catchup to now-required <sys/module.h> for PowerPC

Prefer new location of pci include files (which have only been in the
tree for two or more years now), except in a few places where there's
code to be compatible with older versions of FreeBSD.

Add a pcib variant to allow us to fix up interrupt assignments.

We probably want to do something wrt bus enumeration as well at some point.
