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.

Some filesystems (notably FAT/exFAT only store timestamps with 2 seconds of precision, so by sleeping for 3 seconds, we can ensure that the timestamps of files stored by dirstate will appear older than the dirstate file, and therefore we'll be able to get stable output from debugdirstate. If we don't do this, the test can be slightly flaky. $ sleep 3 $ hg status $ hg debugdirstate --no-dates n 644 10 set inside/f1
