Add a missing barrier in irongate_conf_read0().

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.
- Check register offset of pci_conf_read() in MD part. It returns (pcireg_t)-1
if it isn't accessible.
- Decode Extended Capability in PCI Extended Configuration Space.
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
- Access Control Services
- Alternative Routing-ID Interpretation
- Address Translation Services
- Single Root IO Virtualization
- Page Request
- TPH Requester
- Latency Tolerance Reporting
- Secondary PCI Express
- Process Address Space ID
- LN Requester
- L1 PM Substates
The following extended capabilities are not decoded yet:
- Root Complex Internal Link Control
- Multi-Function Virtual Channel
- RCRB Header
- Vendor Unique
- Configuration Access Correction
- Multiple Root IO Virtualization
- Multicast
- Resizable BAR
- Dynamic Power Allocation
- Protocol Multiplexing
- Downstream Port Containment
- Precision Time Management
- M-PCIe
- Function Reading Status Queueing
- Readiness Time Reporting
- Designated Vendor-Specific

branches: 1.9.6; 1.9.24;
Do a minor cleanup of alpha (this will make applying pullups post branching
easier).
u_int{8,16,32,64}_t -> uint{*}_t
Change all old-style definitions to C89 prototypes.
Whitespace cleanup.
Constification in db_disasm.c

Major cleanup of alpha device drivers.
Switch to CFATTACH_DECL_NEW.
struct device * -> device_t
struct cfdata * -> cfdata_t
Use of device_xname. No direct access to struct device members.
Use aprint* (not complete).
