designated initializers.
I have not built every extant kernel so I have probably broken at
least one build; however I've also found and fixed some wrong
cdevsw/bdevsw entries so even if so I think we come out ahead.
While here, rectify related bug where if gethostname() failed, login
would null-terminate uninitialized stack trash and cheerfully pass it
on to kerberos. In this case, revert to "amnesiac" instead.
SIGHUP,SIGINT,SIGTERM on startup, so make those also conditional to isc_bind9.
The net effect of this was that dhclient blocked the 3 signals for both
itself and its progeny so /etc/rc.d/dhclient restart would not work.
staggering impact on performance. When running sendto() in a loop,
the improvement is 200k more calls per second with an inlined __thread
curlwp as opposed to the default. In other words, it shaves off hundreds
of CPU cycles per call (~20%). Even just eliminating the x86_curlwp()
call in favor of an inline gives an improvement of 60k calls per second.

It is tested only on ARMv7 CPUs yet, for example,
-m evbarm (-a earm) kernel=BEAGLEBONE.
values are rounded to 53 bit mantissa in teh x87 registers.
This hasn't been true since Nov 11 2013.
Forcing a store-load for 'double' in STRICT_ASSIGN() seems to fix things
(at least enough for the few random test cases).
I suspect the code could be changed so that the number of mantissa bits
didn't matter.
Tested on X68030. Needs tests on 040 and 060turbo
(though it should work as other m68k ports).
The x68k port implemented 68060 support including these vector handlers
as early as amiga back in 1996, but even after amiga's locore.s was
improved several times (updating vectors at runtime to switch handlers
per CPU types etc.), x68k's one has not been updated.
After that, atari and mac68k pulled amiga's implementation,
hp300 pulled mac68k, and then most other m68k ports pulled hp300 ones.
Probably that's the reason why only x68k had different implementations
(i.e. no reason that avoids using common handler implementation),
and now it's time to prepare common arch/m68k/m68k/busaddrerr.s.
