e1b9adcc58 Make sleepq_wake() type void. The return value hasn't been used in 
almost 6 years.  Even if it were, returning an arbitrary lwp is a bit
of a wonky interface and can really work only when expected == 1.

d6454414fd Add a RUMP_USE_CTOR compile-time switch. If defined, use 
__attribute__((constructor)) to determine which rump kernel components
and kernel modules are linked into the rump kernel.  If not defined
(default), use the regular approach with link sets.

This option is aimed to fix problems with toolchains where using link
sets is not possible because the linker does not generate the requisite
__start/__stop symbols for the link set sections (e.g. GNU gold, OS X, ...).

afbb108620 domains are attached by module(-like) constructors, so no need to

ee62fa6483 Include LIST_ENTRY() in "struct rump_component". 
Main benefit: rump_component_load() can now be called from an
early-running constructor since the routine doesn't need to allocate
memory.

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.
