test-obsolete: update extension in test to actually work This hasn't been testing anything since partway through the 3.7 cycle due to unrelated refactoring. Sadly, the behavior it was trying to prevent reemerged in the codebase at that time. A fix is in the next patch, because proving that the fix was actually correct ended up being trickier than I expected.

bundle2: properly request phases during getbundle getbundle was requesting the "phase" namespace instead of the "phases" namespace, which led to the client still requesting the phases separately after getbundle finished.

rebase: handle successor targets (issue5198) When a parent has a successor (indicated by revprecursor in state), we need to use it.

debugbundle: add tests for debugbundle output with bundle2

revert: mention ui.origbackuppath in the command help

help: wrap ".orig" in rst quotes Apparently, .orig. is a macro for man pages so we need to wrap it in quotes to silence lintian warnings.

parser: shorten prefix of alias parsing errors These messages seemed to be a bit long. We should try making them fit to 80-col console.

parser: rephrase "'$' not for alias arguments" message Say which symbol caused the error. The word "alias" is removed since these messages are prefixed by "failed to parse ... revset alias "...":".

debugbundle: handle the --all option for bundle2

manifest: improve filesnotin performance by using lazymanifest diff lazymanifests can compute diffs significantly faster than taking the set of two manifests and calculating the delta. when running hg diff --git -c . on Facebook's big repo, this reduces the run time from 2.1s to 1.5s.
