Change Linux fasttimer implementation back to RDTSC - using a reliable syscall was REALLY chewing CPU time.  Sigh.  I didn't realize how incredibly often this gets called.  So, back to the assembly.
But be more careful with CPU clock count on linux, so the fasttimer values are much more accurate than they were the last time we were with RDTSC, in absolute terms - back in the right order of magnitude anyway.

Also change many instances of Mhz to MHz.
Also some minor comment fixes.

more reliable fix based on feedback from Richard.  dicked with the Darwin results too since those seemed wrong based on the same feedback (also covered in test plan).

Gosh, the mac prototypes for get_cpu_clock_count_64 have always been wrong, but the compiler didn't start caring until I made these proper member functions.

fixed.

pull in the linux+solaris fast-timers impl from snowglobe, fit it into viewer2, start moving headers around.

For EXT-4222: Switching outfits sometimes causes me to wear both, and show previous outfit as worn.  Postpone appearance change until wearables have resolved.

(this backs-out my backout, now that I'm happy the original merge works okay :))

This got pushed too early - sorry.  Sigh.

fixed fast timer values being multiplied by 256

can call LLFastTimer::nextFrame with timers still on the stack...first step towards more flexible data gathering
LLInstanceTracker works with statically allocated instances now

Ok, finally got this to a point where it doesn't break the build and I can check
in. llcommon can be built as a shared library (disabled but can be enabled with
cmake cache var LLCOMMON_LINK_SHARED.
