* src/bison.simple: Remove a useless #line directive.

s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
* src/output.c (get_lines_number): New.
(output_parser): Adjust, now takes care about the lines of a
output muscles.
Fix line numbering.
(actions_output): Computes the number of lines taken by actions.
(output_master_parser): Insert new skeleton which is the name of
the output parser file name.
