a kernel history, settable via the SCDEBUG_KERNHIST flag.
this requires a fairly significantly different set of messages than the
normal debug as histories are restricted:
- each message can take one literal format string and upto 4
arguments
- the arguments can not be strings if you want vmstat -u to
work (this could be fixed, and i might, as it would be nice
if we could print syscall names as well as numbers.)
introduce SCDEBUG_DEFAULT that is settable in the kernel config.
fix a problem in kernhist_dump_histories() where it would crash when a
history with no allocated entries was found.
extend kernhist_dumpmask() to handle the usbhist and scdebughist.
The last remnants of the former were just removed from src by
pronchery.
Bump date.
XXX: probably WSDISPLAY_SPROGRESS needs removal too -- back to you,
pronchery!
- 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.

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

- Multi-Function Virtual Channel
- RCRB Header
- Vendor Unique
- Configuration Access Correction
- Multiple Root IO Virtualization

request) to have valid data ready, so the driver didn't work very well.
Now the MR is sent in configurable intervals (hw.hythygtemp0.interval)
using callout(9), so that valid data is immediately available for
sysmon's sensor refresh. When the refresh comes too close after the last
MR, then the previous values are used.
