Missing splx() in hil_thread(). This turned out to be harmless due to the
way this code works (always ends up in tsleep eventually), but it never hurts
to be correct.

Make hil(4) shared interrupts aware, by exiting early if the stat register
does not indicate data being available; for some reason on hppa hil_intr()
gets invoked when serial ports interrupt.

Handle loop reconfiguration in a kernel thread, instead of doing it from
interrupt context.

Postpone the hil console detection logic to the first detection of a keyboard.

On hp300, hil would claim console against dnkbd if no dnkbd was found at

Postpone the hil console detection logic to the first detection of a keyboard.

On hp300, hil would claim console against dnkbd if no dnkbd was found at
the time the loop is probed, even if the loop is empty. Because of this,
plugging dnkbd later would not select it as console keyboard, which is
really annoying on kernels without wsmux, such as hp300 RAMDISK.
Now the first keyboard plugged will become the console keyboard, whatever
its type.

No functional change on hppa, since the console path gives a definite console
device setting.

Do not invoke hil_process_pendinc() from the interrupt handler if the loop
is marked as busy.

Simplify loop reconfiguration code.

If the loop is empty when we probe it, enable the interrupt anyways, so that
we can react on post-boot device plugs.

Reliability fixes:
- Let the loop initialize completely before attempting to probe its devices.
Fixes the "no answer from device 1" problem.

Allow send_hil{,dev}_cmd to return failure, and handle this where
applicable.

During device probe, if a device does not answer commands, display a warning
message. This apparently happens on hp300 when the console is configured
as remote (i.e. serial console). Unplugging and replugging the device works
fine afterwards...

behave correctly for some reason.

Leaving console polling mode works now, and workaround boot -a slow response

Real polled mode console support, enough to play hangman in ddb.
Still a minor issue left for tomorrow.
