Subject: Summer cleaning - removed a lot of llcommon dependencies to speed up
 build times consolidated most indra-specific constants in llcommon under
 indra_constants.h fixed issues with operations on mixed unit types (implicit
 and explicit) made LL_INFOS() style macros variadic in order to subsume other
 logging methods such as ll_infos added optional tag output to error recorders

Subject: SH-4374 FIX Interesting: Statistics Object cache hit rate is always
 100% moved object cache sampling code so that it actually gets executed
 default values for stats are NaN instead of 0 in many cases
