ddb: safely copy symbol names into the symtab structure
Use strncpy instead of strcpy to copy the name of a symbol into the symtab structure. Make sure that the string is properly terminated. Found using Coverity. * ddb/db_sym.c (db_add_symbol_table): Use strncpy instead of strcpy, ensure string termination.
