rHG60213a2eca81: patch: do not cache translated messages (API)
Summary

Previously the code caches i18n._ results in module variables. That causes
issues after an encoding change. Instead of invalidating them manually, we
now just recalculate the translated messages every time filterpatch gets
called.

This makes test-commit-interactive.t pass regardless of whether chg or
demandimport is used or not.

.. api: patch.messages now lives in patch.getmessages().

Extensions adding new messages should now wrap the `patch.getmessages`
method instead of changing `patch.messages` directly.

yuja added a subscriber: yuja.

So the messages may be rolled back, which seems to be against the original
intent, "take messages out of the function so that extensions can add entries."

Since extensions have to wrap the _getmessages() function, the messages
table isn't necessary, so we don't need the callback mechanism, too.
Alternatively, the messages table could keep the raw (untranslated) messages,
to which gettext() will be applied later.

messages = {
    ...
        'discard': "discard change %d/%d to '%s'?",
}
i18nblahblah = messages.... # tell hggettext to extract strings

....
    i18n.gettext(messages[k][op])
