* src/output.c (prepare): Add prefixed names.

* src/output.c (prepare): Add prefixed names.
(output_parser): Output semantic actions.
(output_parser): Fix bug on '%%line' directives.
* src/output.c (output_headers): Remove. The C code printed by this
function should now be in the skeletons.
(output_trailers): Remove.
(output): Disable call to 'reader_output_yylsp'.
(output_rule_data): Do not output tables to the table obstack.
* src/output.c: Remove some C dedicated output.
Improve the use of macro and output obstacks.
(output_defines): Remove.
* src/output.c (output_token_translations): Associate 'translate'
table with a macro. No output to the table obstack.
(output_gram): Same for 'rhs' and 'prhs'.
(output_stos): Same for 'stos'.
(output_rule_data): Same for 'r1' and 'r2'.
(token_actions): Same for 'defact'.
(goto_actions): Same for 'defgoto'.
(output_base): Same for 'pact' and 'pgoto'.
(output_table): Same for 'table'.
(output_check): Same for 'check'.
* src/output.c (output_table_data): New function.
(output_short_table): Remove.
(output_short_or_char_table): Remove.
* src/output.c (output_parser): Replace most of the skeleton copy code
with something new. Skeletons are now processed character by character
rather than line by line, and Bison looks for '%%' macros. This is the
first step in making Bison's output process (a lot) more flexible.
(output_parser): Use the macro table.
