* Provide proper definitions and use these.
* Clarify the evaluation of _STA.
* Mark the state of a sensor according to the return value from _STA.
* Share the basic object evaluation in _BIF and _BST.
* Verify the object types before using the objects.
* Be aware of bogus values from _BIF and _BST, as noted in the
specification.
Despite of the list, functional change should be minimal. Ok pgoyette@.
on error, that leaves the cgd_softc in an inconsistent state.
Fixes a crash during shutdown reported by Patrick Welche. Thanks
to Patrick for reporting and for testing the fix.
__assert -> kern_assert
__sigtimedwait1 -> sigtimedwait1
__wdstart -> wdstart1
The rest are MD and/or shared with userspace, so they will require
a little more involvement than what is available for this quick
"ride the 5.99.24 bump" action.
#if NBPFILTER is no longer required in the client. This change
doesn't yet add support for loading bpf as a module, since drivers
can register before bpf is attached. However, callers of bpf can
now be modularized.
Dynamically loadable bpf could probably be done fairly easily with
coordination from the stub driver and the real driver by registering
attachments in the stub before the real driver is loaded and doing
a handoff. ... and I'm not going to ponder the depths of unload
here.
Tested with i386/MONOLITHIC, modified MONOLITHIC without bpf and rump.

usbd_open_pipe_intr() allocates a usbd_xfer_handle for pipe->intrxfer.
Most usb device drivers using interrupt pipes call usbd_abort_pipe()
then usbd_close_pipe(), usbd_close_pipe() is supposed to free pipe->intrxfer.
But usbd_abort_pipe() calls [uoe]hci_device_intr_abort() which,
if the xfer aborted is pipe's intrxfer, sets pipe->intrxfer to NULL.
So usbd_close_pipe() can't free it and the usbd_xfer_handle is lost.
To fix this, in usbd_abort_pipe() remember the pipe->intrxfer's value
on entrie, and if it's different after usbd_ar_pipe(), call
usbd_free_xfer with the original value.
Confirmed to fix the memory leak on close() with umodem(4) and
uplcom(4).
on SPARCstation-4/5, and emulated by qemu to idle the simulator
when the CPU is idle. Infos about the registers from the linux driver.
Not enabled by default because it can cause some Sparc systems to
hang (so says the linux driver).
Only the CPU idle part implemented at this time; fan speed and
Convenience power outlet management to be added.
Tested on qemu.
