Note that HTTPTimeout::sClockWidth is no longer used for HTTPTimeout (as
if it's value became a constant of 0.01, the fraction 10ms / 1s).
A new variable, HTTPTimeout::sClockWidth_10ms is used to calculate
sTime_10ms (only).
Also HTTPTimeout::mStalled and HTTPTimeout::mLowSpeedClock changed units
to the same as of sTime_10ms (time since epoch in 10ms units).
LLInstanceTracker added to llcommon (pulled from llui in v2 for usage elsewhere)
LLEventTimer now using LLInstanceTracker
Updated LLLiveAppConfig (Though it appears unused, really)
processor.h is obsolete, thus removed. (llprocessor.h replaces it)
