The previous name was historical and inconsistent.
* src/muscle-tab.c (define_directive): Use the proper value passing
syntax, based on the muscle kind.
(muscle_percent_variable_update): Use the right value passing syntax.
Migrate from parser_class_name to api.parser.class.
* data/skeletons: Migrate from parser_class_name to api.parser.class.
* doc/bison.texi (%define Summary): Document both parser_class_name
and api.parser.class.
Promote the latter over the former.
This way, it is easier to make sure its implementation is available in
glr.cc too, which is not the case currently.
* data/skeletons/c++.m4 (b4_public_types_define): Move the
implementation of syntax_error...
(b4_public_types_declare): here.
We used to create a short definition of yy::parser with all the
implementations of its member functions outside. But yy::parser is no
longer short and simple to read. Maintaining each function twice is
painful: a lot of redundancy but different indentation levels, output
which depends on whether we are in a header or not (see
d132c2d545), etc.
Let's simplify this and put the implementations into the class
definition itself.
Discussed in this monologue:

* data/skeletons/c++.m4, data/skeletons/lalr1.cc,
* data/skeletons/variant.hh (b4_basic_symbol_constructor_define)
(_b4_token_constructor_declare, b4_token_constructor_declare)
Merge into...
(b4_basic_symbol_constructor_define, _b4_token_constructor_define)
(b4_token_constructor_define): these.
