*** Abort parsing for memory exhaustion (C)
The user actions may now use YYNOMEM to abort the current parse with
memory exhaustion.
User actions may now use `YYNOMEM` (similar to `YYACCEPT` and `YYABORT`)
to abort the current parse with memory exhaustion.
*** Printing locations in debug traces (C)
The `YYLOCATION_PRINT(File, Loc)` macro prints a location. It is defined
when (i) locations are enabled, (ii) the default type for locations is
used, (iii) debug traces are enabled, and (iv) `YYLOCATION_PRINT` is not
already defined.
Users may define `YYLOCATION_PRINT` to cover other cases.
