push: update bookmarks within the remote lock Updating bookmarks is part of the push. It should be done within the same lock as the other steps of the push.

hgweb: refresh repository using URL not path (issue4323) hgweb detects out-of-date repository instances (using a highly suspect mechanism that should probably be fixed) and obtains a new repository object if needed. This patch changes the repository object copy to use the repo URL (instead of path). This preserves more information about the source repository and allows bundles to be served through hgweb. A test verifying that bundles can now be served properly via `hg serve` has been added.

obsmarker: add `date` as an explicit field The markers are now 5-item tuples (concluded by the date). The obsstore.fields contents have been updated accordingly. There is no change to the on-disk format yet, so the date has to be extracted every time we read binary markers and re-injected each team we write them. This introduces a slowdown that will be solved when a new version of the format is added. Such a slowdown was already introduced by the evolve extension anyway.

obsstore: add fields attribute to track each field in a marker We are going to increase the amount of data explicitly stored in obsolescence markers. This mean we are going to have a longer tuple and some values will be shuffled around. So we add a ``fields`` attribute to the obsstore class to keep track of what entry is what. This will be useful for extensions and for documentation purpose.

debugobsolete: explicitly display date in the output As the date is becoming a first-class citizen, we are displaying it in an explicit field. As a bonus it is now readable by humans.

obsolete: add a date argument to the `createmarkers` function The function is now just passing the value to create markers.

debugobsolete: use the new date argument on obsstore.create Now that we have this new argument, we can just use it.

obsstore: add an explicit `date` argument to obsstore.create The date will become an official field in the markers (and ultimately in the on-disk format). We start by making it an official argument for the function.

obsolete: explicitly pass metadata argument using keyword argument We are about to add more arguments to this function (date, parents, etc). Passing metadata as a keyword argument gives us more flexibility when adding them.

obsmarker: add a `flags` method We introduce a proper method to access the flag information.

test-treediscovery: update output after merge Recent change in the push process introduced an extra listing of the phase name space before the push (on default). Meanwhile on default, a fix introduced a new test with debug output. We update the test output to be correct.

revert: add an XXX about rename tracking We check for rename information in the dirstate. This is probably not enough to preserve this behavior when using an explicit target rev. I just spotted this while working on this code, but this is outside the scope of my series so I'm just adding a comment to highlight this suspicious situation.
