As usual, version 8.14 of Coq introduces new warnings, some of which cannot be honored without breaking backward compatibility with 8.13 and earlier. (Grmph.)

This PR is a best effort: address the warnings that can be addressed, and silence the others.

Backward compatibility was successfully tested with Coq 8.13, 8.11, and 8.9.

This avoids a new warning of Coq 8.14.
Warning "deprecated hint rewrite without locality" cannot be addressed:
the suggested fix (qualify with Global or Local or [#export])
is not supported by Coq 8.11 to 8.13 !

Warning "deprecated instance without locality" is turned off
for generated file cparser/Parser.v only.

Menhir needs to be changed so as to generate the `Global` modifier
that would silence this warning.
