Have more complete shift traces.

Browse Source 
* data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT
to report Shifts instead of ad hoc YYDPRINTF invocations,
including for the error token.
* data/lalr1.cc (symprint_): Output the location.
* tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't
output the location within the %printer.
Activate GLR tests, at least to make sure they compile properly.
They still don't pass though.
* tests/calc.at: Adjust expect verbose output, since now "Entering
state..." is on a different line than the "Shifting" message.
