dirstate: move management of nonnormal sets into dirstate map The dirstate map owns the nonnormal sets, and so should be the class to update them. A future implementation of the dirstate will manage these maps differently. The action of clearing ambiguous times is now entirely controlled by the dirstate map, so it moves there too.

bundlerepo: rename "bundle" arguments to "cgunpacker" "bundle" was appropriate for the bundle1 days where a bundle was a changegroup. In a bundle2 world, changegroup readers are referred to as "changegroup unpackers." Differential Revision: https://phab.mercurial-scm.org/D1383

test-pattern: actually update tests using the patterns We mass update the tests now. This will help the next soul touching the http protocol.

test-pattern: substitute the HTTP log timestamp too We add a pattern matching the infamous timestamp in http log. Now, we should be able to have change appears in https log without having to re-glob the whole thing over and over.
