[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.

Align the PCI Express #defines with the style used for the PCI-X
#defines. This also has the advantage that it makes the names more
compact, iand also allows us to correct the non-uniform naming of
the PCIM_LINK_* defines, making them all consistent amongst themselves.

This is a mostly mechanical rename:
s/PCIR_EXPRESS_/PCIER_/g
s/PCIM_EXP_/PCIEM_/g
s/PCIM_LINK_/PCIEM_LINK_/g

When this is MFC'd, #defines will be added for the old names to assist
out-of-tree drivers.

- Make parsing of PCI-e extended capabilities assume that future version
numbers are backwards compatible.
- Add new AER error descriptions.

Add a new -e flag to pciconf(8)'s list mode to display PCI error details.
Currently this dumps the status of any error bits in the PCI status register
and PCI-express device status register. It also lists any errors indicated
by version 1 of PCI-express Advanced Error Reporting (AER).

Only attempt to list extended capabilities for devices that have a
PCI-express capabilities. Non-PCI-express PCI devices may simply ignore
the upper bits in a config register address effectively aliasing the
device ID register to 0x100 rather than returning 0xFFFFFFFF. Previously
the code relied on these reads returning 0xFFFFFFFF.

- Use 'sta' to hold the PCIR_STATUS register value instead of 'cmd' when

- Add register definitions related to extended capability IDs in
PCI-express. I used PCIZ_* for ID constants (plain capability IDs use
PCIY_*).
- Add register definitions for the Advanced Error Reporting, Virtual
Channels, and Device Serial Number extended capabilities.
- Teach pciconf -c to list extended as well as plain capabilities. Adds
more detailed parsing for AER, VC, and device serial numbers.

Actually support the new HT capability type from HT 2.00b.

MFC after: 3 days

- HT 2.00b added a new flag to the MSI mapping HT capability to indicate
that the MSI mapping window is fixed at 0xfee00000 and the capability
does not include two more dwords used to program the address. Supporting
this mostly results in quieting spurious warnings during boot about
non-default MSI mapping windows.
- HT 2.00b also added a new HT capability type, so support that in pciconf.

- Teach pciconf(8) to list the PCI capabilities supported by each device
via a new -c flag to be used with -l. Some simple parsing code is
present for the following capabilities: Power Management, AGP, VPD,
MSI, PCI-X, HyperTransport, Vendor-specific, EHCI Debug Port, PCI-PCI
bridge subvendor ID, PCI-express, and MSI-X.
- Fix a few warnings in pciconf.c.
- Update some cruft in pciconf(8):
- PCI 2.1 is no longer a revolutionary standard, and subvendor ID's are
fairly common at this point, so reflect that.
- Header type 2 is used for PCI-CardBus bridges.
- Describe the -v option for -l after completing the basic -l description
instead of disrupting the flow in the middle.
