chgserver: mark as a built-in extension

chgserver: import background server extension from cHg This extension is copied from https://bitbucket.org/yuja/chg/ -r 86feb5f2e971 It could be imported as mercurial/chgserver.py, but in that case, we would have to resolve circular import between chgserver and commandserver. So I decided to keep it as an extension. chgserver.chgcmdserver -> commandserver.server commandserver._servicemap -> chgserver.chgunixservice

rebase: small refactoring to allow better extensibility from extensions Inhibit, one of evolve's extension, would like to change the way rebase works with obsolete changesets. During a rebase with inhibit, the inhibition of the obsolescence markers should be lifted for the rebase. With this small refactoring, inhibit and can wrap the _filterobsoleterevs function to lift inhibition cleanly and at the same time this change makes rebases' code more legible.
