bookmarks: automatically advance bookmark on naked update (BC) (issue2894)

qimport: back out 2eec74d7ce95 This patch presumed mq csets must always be secret, which isn't yet established.

phases: only synchronize on common changeset when push fails If push failed we should not expect the pushed changeset to exist on remote. The common set before the push is used for phase related operation instead of common + missing. Note: * We still pull phase data even if push fails * We still try to push data even if push fails (same than bookmark)

discovery: diet discovery.prepush from non-discovery code The ``discovery.prepush`` function was doing multiple things not related to discovery. This changeset move some code into the ``localrepo.push`` method. The old ``discovery.prepush`` function jobs is now restricted to checking for multple head creation. It was then renamed ``discovery.checkheads``. This new ``discovery.checkheads`` function may receive several other changes in the future but we are a bit too much near the freeze for a wider refactoring.

qfinish: set all qfinished patch as draft, not only qbase Fix a silly bug.

largefiles: test and simplify empty directory removal in remove

tag: invalidate tag cache immediately after adding new tag (issue3210) New tags were written to .hgtags / .hglocaltags without updating or invalidating the localrepo cache. Before afd459933d5f a lock was acquired soon after the new tags had been written, and that invalidated the cache so the new tags for example could be seen in pretxncommit hooks. With afd459933d5f the lock had already been acquired at this point and the missing cache invalidation was exposed. The tag caches will now explicitly and immediately be invalidated when new tags are added.

mq: ensure mq changesets are set to secret when no phase data are found

mq: qimporting revision set them to secret

mq: have mq create secret changeset only
