Move the token type and YYSTYPE in the parser class.
* data/lalr1.cc (stack.hh, location.hh): Include earlier.
(parser::token): New, from the moved free definition of tokens.
(parser::semantic_value): Now a full definition instead of an
indirection to YYSTYPE.
(b4_post_prologue): No longer included in the header file, but
in the implementation file.
* doc/bison.texi (C+ Language Interface): Update.
* src/parse-gram.y: Support unary %define.
* tests/actions.at: Define global_tokens_and_yystype for backward
compatibility until we update the tests.
* tests/calc.at: Idem.
(first_line, first_column, last_line, last_column): Define for lalr1.cc
to simplify the code.

Changes in version 2.1a:
* lalr1.cc: The token and value types are now class members.
The tokens where defined as free form enums and cpp macros. YYSTYPE
was defined as a free form union. Both are now class members:
tokens are enumerations of the `yy::parser::token' struct, and the
semantic values have the `yy::parser::semantic_type' type.
If you do not want or can update to this scheme, the directive
`%define "global_tokens_and_yystype" "1"' triggers the global
definition of tokens and YYSTYPE.
