Akim Demaille ba469451d8 diagnostics: improve the accuracy for %error-verbose ...

Avoid duplicate warnings about %error-verbose, once for deprecation,
another for duplicate.  Keep only the duplicate warning for the second
occurrence of %error-verbose.

This will help removal fixits.

* src/scan-gram.l (%error-verbose): Return as a PERCENT_ERROR_VERBOSE
token.
* src/parse-gram.y (do_error_verbose): New.
Use it.
* src/muscle-tab.c (muscle_percent_variable_update): Handle pseudo
variables such as %error-verbose.
