pooka | Define rump_nativeabi_p() under arch, where one would logically expect
it to be defined.

Rototill a bit, and attempt to disguise it as non-gratuitous.
Add arch/generic and move non-x86 files from rumpkern/ there. Also,
move files from arch/i386 to arch/x86, and make both i386 and x86_64
use those.
This clarifies the situation with what is MD vs. MI code.

(for those who forget, x86 requires MD code because rump kernels
use the same ABI as kernel modules)

Put the kernelside rump kernel headers into <rump-sys> instead of
sprinkling them around the faction directories. Avoids having
to add a CPPFLAGS (or several) to pretty much every component
Makefile.
Leave compat headers around in the old locations.
The commit changes some autogenerated files, but I'll fix the
generators shortly and regen.

pooka | Apparently not all ports define struct clockframe in cpu.h, so we cannot
provide our definition that way. Instead, generate the struct clockframe
passed to hardclock() in MD code.

pooka | branches: 1.2.4; 1.2.6; 1.2.10; 1.2.12;
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.

msaitoh | Serialize rdtsc using with lfence, mfence or cpuid to read TSC more precisely.
x86/x86/tsc.c rev. 1.67 reduced cache problem and got big improvement, but it
still has room. I measured the effect of lfence, mfence, cpuid and rdtscp.
The impact to TSC skew and/or drift is:
AMD: mfence > rdtscp > cpuid > lfence-serialize > lfence = nomodify
Intel: lfence > rdtscp > cpuid > nomodify
So, mfence is the best on AMD and lfence is the best on Intel. If it has no
SSE2, we can use cpuid.
NOTE:
- An AMD's document says DE_CFG_LFENCE_SERIALIZE bit can be used for
serializing, but it's not so good.
- On Intel i386(not amd64), it seems the improvement is very little.
- rdtscp instruct can be used as serializing instruction + rdtsc, but
it's not good as [lm]fence. Both Intel and AMD's document say that
the latency of rdtscp is bigger than rdtsc, so I suspect the difference
of the result comes from it.
