spin in a loop eating CPU time. This bug has existed since the
TI-RPC import. The problem is that we should only enter the select
loop if at least one TCP server was started. Fix this by having
the master nfsd become a UDP server itself if there are no TCP
servers.
Also improve/correct the code for cleaning up slave nfsd processes
and unregistering with rpcbind when the master nfsd exits.
One issue that remains open is that if a slave nfsd dies, then all
nfsds will shut down. This is because nfssvc() in the master nfsd
returns 0 when the master nfsd receives a SIGCHLD.

Use the normal interrupt handler (npx_intr()) instead of a special
probe-time interrupt handler, although this causes problems due to
the bus_teardown_intr() not actually even tearing down the interrupt
(these problems were avoided by doing interrupt attachment for the
special interrupt handler directly). Fixed minor bitrot in comments.
The reason for the npxprobe()/npxprobe1() split mostly went away at
about the same time it was made (in 1992 or 1993 just before the
beginning of history). 386BSD ran all probes with interrupts completely
masked, and I didn't want to disturb this when I added an irq probe
to npxprobe(). An irq (not necessarily npx) must be acked for at least
external npx's to take the cpu out of the wait state that it enters
when an npx error occurs, so the probe must be done with a suitable
irq unmasked. npxprobe() went to great lengths to unmask precisely
the npx irq.
Running probes with all interrupts masked was never really needed in
FreeBSD, since FreeBSD always masked interrupts well enough using
splhigh(), but it wasn't until rev.1.48 (1995/12/12) of autoconf.c
that all probes were run with CPU interrupts enabled. This permits
npxprobe() to probe its irq using normal interrupt resources. Note
that most drivers still can't depend on this. It depends on the
interrupt handler being fast and the irq not being shared.
lost when the buggy code goes away completely:
- don't assume that the npx irq number is >= 8. Rev.1.73 only reversed
part of the hard-coding of it to 13 in rev.1.66.
- backed out the part of rev.1.84 that added a highly confused comment
about an enable_intr() being "highly bogus". The whole reason for
existence of npxprobe() (separate from the main probe, npxprobe1())
is to handle the complications to make this enable_intr() safe.
- backed out the part of rev.1.94 that modified npxprobe(). It mainly
broke the enable_intr() to restore_intr(). Restoring the interrupt
state in a nested way is precisely what is not wanted here. It was
harmless in practice because npxprobe() is called with interrupts
enabled, so restoring the interrupt state enables interrupts. Most
of npxprobe() is a no-op for the same reason...

to work, but haven't really due to subtle differences in structs etc.
This is still not perfect (some ioctls are still known not to work, while
others haven't been tested at all), but it's enough to get Debian's ifconfig
to produce relatively sane output.
More work will be needed to get all ioctls (or at least a reasonable subset)
working, and to support the Cisco Aironet config tool mentioned in the PR.
