record: prevent commits that don't pick up dirty subrepo changes (issue6102)
This path covers interactive mode for commit, amend, and shelve, as well as the
deprecated record extension. Since shelf creation uses commit without -S in the
non-interactive case, aborting here should be OK. (I didn't check what happens
to non interactive shelve creation if `ui.commitsubrepos=True` is set.)
subrepoutil.precommit() will abort on a dirty subrepo if the config option isn't
set, but the hint recommends using --subrepos to commit. Since only the commit
command currently supports that option, the error has to be raised here to omit
the hint.
Doing the check before asking about all of the hunks in the MQ test seems like
an improvement on its own. There's probably an additional check on this path
that can be removed.
