revert: remove dangerous `parents` argument from `cmdutil.revert()`
As we found out the hard way (thanks to spectral@ for figuring it
out!), `cmdutil.revert()`'s `parents` argument must be
`repo.dirstate.parents()` or things may go wrong. We had an extension
that passed in the target commit as the first parent. The `hg split`
command from the evolve extension seems to have made the same mistake,
but I haven't looked carefully.
The problem is that `cmdutil._performrevert()` calls
`dirstate.normal()` on reverted files if the commit to revert to
equals the first parent. So if you pass in `ctx=foo` and
`parents=(foo.node(), nullid)`, then `dirstate.normal()` will be
called for the revert files, even though they might not be clean in
the working copy.
There doesn't seem to be any reason, other than a tiny performance
benefit, to passing the `parents` around instead of looking them up
again in `cmdutil._performrevert()`, so that's what this patch does.

==================================== Testing head checking code: Case B-6 ==================================== Mercurial checks for the introduction of new heads on push. Evolution comes into play to detect if existing branches on the server are being replaced by some of the new one we push. This case is part of a series of tests checking this behavior. Category B: simple case involving pruned changesets TestCase 6: single changesets, pruned then superseeded (on a new changeset) .. old-state: .. .. * 1 changeset branch .. .. new-state: .. .. * old branch is rewritten onto another one, .. * the new version is then pruned. .. .. expected-result: .. .. * push allowed .. .. graph-summary: .. ..
