cmMem.c : Added string tables for 'filename' and 'function name' strings
in the cmMmRecd_t record.
Previously the 'fileNameStr' and 'funcNameStr' were assumed to be stored
in static memory and therefore did not require duplication. If the
strings however originated in a dynamic library then the string pointer
would be invalid after the library is unloaded. Accessing these fields
would then result in a crash.
