test/call_suite_aggrs: - refactored generator code a bit to be simpler, write cleaner output, have better shareability and clarity - added rtypes w/ default value nil to config.lua, to self document - shared some code under test/common/ - fixed nonemptyaggrs sigs and cases.h (accidentally overwritten with cases having empty aggrs)
