mutex.
- Don't use callout_drain() to stop the toffhandle callout while holding the
fdc mutex (this could deadlock) in functions called from softclock
(callouts aren't allowed to do voluntary sleeps). Instead, use
callout_stop(). Note that since we hold the associated mutex and are now
using callout_init_mtx(), callout_stop() is just as effective as
callout_drain(). (Though callout_drain() is still needed in detach to
make sure softclock isn't contesting on our mutex before we destroy the
mutex.)
- Remove unused callout 'tohandle' from softc.

interrupt handlers rather than BUS_SETUP_INTR() and BUS_TEARDOWN_INTR().
Uses of the BUS_*() versions in the implementation of foo_intr methods
in bus drivers were not changed. Mostly this just means that some
drivers might start printing diagnostic messages like [FAST] when
appropriate as well as honoring mpsafenet=0.

processing the interrupt events. If we clear them afterwards we
can completely miss some events as the NIC can change the source
flags while we're in the handler. In order to not get another
interrupt while we're in ifp->if_input() with the driver lock
dropped we now turn off NIC interrupts while in the interrupt
handler. Previously this was meant to be achieved by clearing the
interrupt source flags after processing the interrupt events but
didn't really work as clearing these flags doesn't actually
acknowledge and re-enable the events.
This fixes the device timeouts seen with the VMware LANCE.
- Relax the watchdog timer somewhat; don't enable it until the last
packet is enqueued and if there is a TX interrupt but there are
still outstanding ones reload the timer.

Please note that the files
sys/dev/myri10ge/{mcp_gen_header.h,myri10ge_mcp.h} are internally
shared between all our drivers (solaris, macosx, windows, linux, etc).
I'd like to keep these files unchanged, so I can just import newer
versions of them when the firmware API/ABI changes. This means I'm
stuck with some of the crazy-long #define names, and possibly
non-style(9) characteristics of these files.
Many thanks to mlaier for doing firmware(9) just as I
needed it, and to scottl for his helpful review.
