changed unit declarations macros to make a lot more sense

continued conversion to units system
made units perform type promotion correctly and preserve type in arithmetic
e.g. can now do LLVector3 in units
added typedefs for remaining common unit types, including implicits

changed Units macros and argument order to make it more clear
optimized units for integer types
fixed merging of periodicrecordings...should eliminate duplicate entries in sceneloadmonitor history

improved unit tests for LLUnit
renamed LLUnit to LLUnitImplicit with LLUnit being reserved for
explicit units

simplified llfasttimer code down to 2 classes
llunit unit conversion now done in floating point or 64 bit integer precision,
depending on source type

Refactored the CProcessor class into LLProcessorInfo.
