context: remove unreliable accessor methods from committablectx There are two caching routes for (propertycache-ed) "_status" below in committablectx: - invoking "status()": "dirstate.status()" is invoked, and the result of it is cached into "_status". In this case, any of "listignored", "listclean" and "listunknown" may be True. - accessing "_status" directly before "status()": Own "status()" is invoked, but all of "listignored", "listclean" and "listunknown" arguments are False, in this case. "ignored"/"clean"/"unknown" accessor methods of "committablectx" use corresponded fields of "_status", but these fields aren't reliable, because these fields are empty when: - "_status" method is executed before accessors, or - "status()" is executed with "list*=False" before accessors In addition to it, these accessors aren't used in the recent Mercurial implementation. At least, removing them doesn't cause any test failures.

context: cache self._status correctly at workingctx.status Before this patch, "workingctx.status" always replaces "self._status" by the recent result, even though: - status isn't calculated against the parent of the working directory, or - specified "match" isn't "always" one (status is only visible partially) If "workingctx" object is shared between some procedures indirectly referring "ctx._status", this incorrect caching may cause unexpected result: for example, "ctx._status" is used via "manifest()", "files()" and so on. To cache "self._status" correctly at "workingctx.status", this patch overwrites "self._status" in "workingctx._buildstatus" only when: - status is calculated against the parent of the working directory, and - specified "match" is "always" one This patch can be applied (and effective) only on default branch, because procedure around "basectx.status" is much different between stable and default: for example, overwriting "self._status" itself is executed not in "workingctx._buildstatus" but in "workingctx._poststatus", on stable branch.

filectx.parents: also fetch the filelog of rename source too we are going to need this filelog for the linkrev adjustment, so we better normalise the list and have the filelog in all case. This is done in a previous changeset to help readability.
