phabricator: pass ui into readurltoken instead of passing repo The goal of this series is to make `hg debugcallconduit` work outside of a hg repo. This patch, removes requirement of repo object from readurltoken as we only need ui there. It also updates the callers to pass in ui instead of repo.

py3: add test-contrib-emacs.t to passing tests list I installed emacs on the server running buildbot and the test started passing on Python 3. Lets add it to the list of passing test. Differential Revision: https://phab.mercurial-scm.org/D6500

phabricator: add commenting to phabsend for new/updated Diffs Especially useful when sending updates to existing Revisions so one can specify the sort of changes e.g. "Address review comments" or "Rebase to tip" If the diff content hasn't changed then it only needs a metadata update which doesn't show in the Phabricator updates UI, so don't add a comment that will.

py3: fix test-bookmarks-corner-case.t For some reasons, the output of print was not going through. Replaced that ui.status(). Differential Revision: https://phab.mercurial-scm.org/D6481

py3: fix test-fix-metadata.t # skip-blame as just b'' prefixes Differential Revision: https://phab.mercurial-scm.org/D6480

py3: add b'' prefix at one place in run-tests.py #skip-blame because just b'' prefix Differential Revision: https://phab.mercurial-scm.org/D6482

copies: separate added/removed files by newline instead of null This makes it more consistent with how we encode copies (newline-separated lists of null-separated pairs). This perhaps makes {extras} a little less readable (?) despite avoiding the escaping. I don't know how I feel about this patch. I'm okay with it being queued or dropped.

copies: also encode p[12]copies destination as index into "files" list This is mostly for consistency with the filesaddes/filesremoved fields, but it should also save a bit of space. Differential Revision: https://phab.mercurial-scm.org/D6431

discovery: be more conservative when adjusting the sample size Since 5b34972a0094, the discovery will increase the sample size when it detect a "complex" undecided set. However this detection focussed on the number of roots only, this could regress discovery performance when the undecided set has many roots that eventually get merged into a few heads. To prevent such misbehavior, we adjust the logic to take in account both heads and roots. The sample size will be increased only if both are especially large. Performance testing on the same case as 5b34972a0094, does not show a significant difference.

rust-dirstate: create dirstate submodule This change is here to facilitate a future patch that is written in a different file. I expect this module to grow a few different files. Differential Revision: https://phab.mercurial-scm.org/D6389
