histedit: hold wlock and lock while in progress Currently, histedit acquires and releases lock and wlock several times during its run. This isn't great because it allows other hg processes to come in and change state. With this fix, lock and wlock are acquired and released exactly once. The change to test-histedit-drop.t is a minor implementation one -- the cache is still correctly invalidated, but it just happens a little later and only gets printed out because of the unrelated --debug flag.

templater: only recursively evaluate string literals as templates (issue4103)

templater: fix escaping in nested string literals (issue4102) Before the templater got extended for nested expressions, it made sense to decode string escapes across the whole string. Now we do it on a piece by piece basis.

shelve: unshelve using an unfiltered repository when evolve is enabled and a hidden obsolete changeset exists in the repository, the strip during unshelve will fail due to filtered revs. we use an unfiltered repository like to repair.strip to strip the proper nodes.

largefiles: update in two steps, handle interrupted updates better An update would try to fetch any missing largefiles after having updated normal files and standins. That could fail or be interrupted and would leave the working directory in a state where the largefiles not only were missing but also were scheduled for remove ... and where the old largefile was left in place. Instead we now remove old largefiles before starting to download and update missing largefiles.

largefiles: inline _updatelfile, prepare for further refactorings
