Akim Demaille 1fa19a7697 api.value.type: diagnose guaranteed failure with --yacc ...

Instead of generating invalid C code, generate an error when --yacc and
'%define api.value.type union' are used together.

* data/bison.m4: Issue an error in this case.
* tests/types.at (%yacc vs. %define api.value.type union): New, check this
error.
* doc/bison.texi (Type Generation): Document it.
* tests/output.at: Check that '-o y.tab.c' and '-y' behave equally
wrt generated file names.
* NEWS (Use of YACC='bison -y'): New.
Promote the use of 'bison -o y.tab.c'.
