hgrc: introduce HGRCSKIPREPO to skip reading the repository's hgrc
We had a way to change the behavior regarding reading the global and user
config, but we had nothing regarding the repository hgrc itself.
This option is useful in situation where scripts need to be able to work around
strange configuration set by the user in his repository. (and were HGPLAIN is
not enough).
