updates
Add additional SLAC Protocol MMEs
Removed constant CHIPSETS from plc.h
Modified pibcomp.c to avoid unecessary display of file/definition size mismatch; redefined some variable types and added definitons for OFF_T_SPEC and ADDR_T_SPEC to types.h
Removed reference to deprecated MS_DISCOVER message; This was never implemented.
Re-declare struct message to exclude struct qualcomm. This is done to simplify notation.
