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
