lalr1.cc: YY_ASSERT should use api.prefix

Browse Source 
Working on the previous commit I realized that YY_ASSERT was used in
the generated headers, so must follow api.prefix to avoid clashes when
multiple C++ parser with variants are used.

Actually many more macros should obey api.prefix (YY_CPLUSPLUS,
YY_COPY, etc.).  There was no complaint so far, so it's not urgent
enough for 3.7.4, but it should be addressed in 3.8.

* data/skeletons/variant.hh (b4_assert): New.
Use it.
* tests/local.at (AT_YYLEX_RETURN): Fix.
* tests/headers.at: Make sure variant-based C++ parsers are checked
too.
This test did find that YY_ASSERT escaped renaming (before the fix in
this commit).
