workingfilectx: add remove and write methods This patch will allow abstracting localrepo.remove / write method to refactor working directory code.

memctx: create a filectxfn if it is not callable This will allow future patches to construct a memctx based on another context or any other store-type object.

test-patchbomb.t: work around Python change d579866d6419 (issue4188) Python 2.7.7 and later (as well as some ubuntu/debian packages of 2.7.6) include a fix that makes the email module more pedantically correct for MIME boundaries, but this breaks our tests. We work around this by filtering the output of any 'hg email' invocations in the test that produce MIME messages.

phase: add a transaction argument to retractboundary We now pass a transaction option to this phase movement function. The object is currently not used by the function, but it will be in the future. All call sites have been updated. Most call sites were already enclosed in a transaction for a long time. The handful of others have been recently updated in previous commit.

phase: add a transaction argument to advanceboundary We now pass a transaction option to this phase movement function. The object is currently not used by the function, but it will be in the future. All call sites have been updated. Most call sites were already enclosed in a transaction for a long time. The handful of others have been recently updated in previous commit. The retractboundary function remains to be upgraded.

pull: pre-filter remote phases before moving local ones We were relying on the phase internals to filter out redundant phase information from remove. However as we plan to integrate phase movement inside the transaction, we want to avoid useless transaction creation on no-op pulls. Therefore we filter out all the information that already matches the current repository state. This will let us create a transaction only when there is actual phase movement needed.

test-check-commit-hg.t: automatically test all 'draft() and ::.' changesets We introduce a test-check-commit-hg.t file that will happily run the check-commit file on all draft changeset under the working directory. This should help newcomers to catch up with the rules. (And will helps old timer from time to time).
