dc8f80f5c3 Put nanosleep() and folks in librump instead of maintaining them in 
the separate rumpkern_time component.  Keeping time-related routines
elsewhere lead to some illogical behavior if you didn't think of linking
in rumpkern_time (hands up everyone who checks the return value of
nanosleep()).

Add warnings if rumpkern_time is linked or used.  I'll remove it in a
month or two instead of now since it was part of a buildrump.sh snapshot
and it's nicer if trying to use it gives a warning instead of an error
in the next snapshot.

a68f9396b6 Change (mostly mechanically) every cdevsw/bdevsw I can find to use 
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.

35bcd6f8af Allow compile-time optimizations to curlwp. This can have a pretty 
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.
