convert: introduce hg.revs to replace hg.startrev and --rev with a revset

The existing knobs for controlling which revisions to convert were often
insufficient. Revsets is a shiny hammer that provides a better solution.

Revsets has been introduced in --rev handling in a lot of other places while
being more or less backwards compatible. Doing the same here would be a much
more elegant ... but that would unfortunately not work in this case.  "--rev 7"
used to mean revision 0 to 7 - it would be an unacceptable change if it
suddenly just meant revision 7.

Instead we introduce a new configuration setting. It will only work for
Mercurial repositories so adding a new commandline option for it would not be a
nice solution.

There is no way to use the fancy deprecation markup for configuration settings
so we just remove the documentation of hg.startrev.
