rebase: properly handle unrebased revision between rebased one

With rebase taking multiple roots it is possible to have revision in the "rebase
domain" not rebased themself. We do not want rebased revision above them to be
detached. We want such revision to be rebased on the nearest rebased ancestors.
This allows to preserve the topology of the rebase set as much a possible

To achieve this we introduce a new state `revignored` which informs
`defineparents` of the situation.

The test in `test-rebase-obsolete.t` was actually wrote and his now fixed.

'''expand expressions into changelog and summaries

This extension allows the use of a special syntax in summaries, which
will be automatically expanded into links or any other arbitrary
expression, much like InterWiki does.

A few example patterns (link to bug tracking, etc.) that may be used
in your hgrc::

  [interhg]
  issues = s!issue(\\d+)!<a href="http://bts/issue\\1">issue\\1</a>!
  bugzilla = s!((?:bug|b=|(?=#?\\d{4,}))(?:\\s*#?)(\\d+))!<a..=\\2">\\1</a>!i
  boldify = s!(^|\\s)#(\\d+)\\b! <b>#\\2</b>!
