grep: put --diff in the first line of usage Differential Revision: https://phab.mercurial-scm.org/D7003

ui: option to preserve the progress bar Some interface like the fast-import format of git are meant for pipe processing. It can be still desirable to have progress bars in this case, but clearing the bar after each output operation is not desirable. Differential Revision: https://phab.mercurial-scm.org/D6843

phabricator: update hgmatcher to cope with the new data format The new conduit format can't be matched by the existing matcher since it shifts all the data into an urlencoded string of JSON, the order of which isn't stable between runs. Instead detect JSON values of params and load them into python dicts, which python will then naturally deep-equal compare. Differential Revision: https://phab.mercurial-scm.org/D7055

phabricator: treat non-utf-8 text files as binary as phabricator requires Phabricator can't cope with text files that are not UTF-8, so requires them to be submitted as binary files instead. This has the unfortunate effect of making them practically unreviewable in Phabricator since it will only display the separate versions of the file in other views, not a diff. `phabread`ing such submissions are similar, since it will just output the binary patch, but `hg import` copes with it fine and `hg diff` afterwards will show the actual changes. It is still a marked improvement over trying to submit them as text, which just leads to corruption (Phabricator will either output ? or HTML entities for non-UTF-8 characters, depending on context). Running decode on the whole file like this seems slightly unfortunate, but I'm not aware of a better way. Needs to be done to p1() version as well to detect conversions to UTF-8.

phabricator: switch to the creatediff endpoint This lets the extension submit binary files, as well as set branch info so that it is exposed in the Phabricator interface. Differential Revision: https://phab.mercurial-scm.org/D7053

phabricator: change conduit data format to match arcanist The existing form isn't handled well by Phabricator for certain data types. Differential Revision: https://phab.mercurial-scm.org/D7052

phabricator: remove tests and all recordings The next commit is going to change the format of conduit API requests so none of the VCR recordings will match and all the tests will fail. Differential Revision: https://phab.mercurial-scm.org/D7051

phabricator: convert phabhunk and phabchange keys to bytes when finalising I thought I had included this code already but I'd missed it out. One of the disadvantages of attrs is that all the keys are unicode strings on py3, but we need them to be byte strings. Differential Revision: https://phab.mercurial-scm.org/D7066

phabricator: add addadded function This is the most complicated part of the new code, and is responsible for adding all added files, whether brand new, copied, or moved. This also includes creating the phabchanges for the original files that have been moved or copied from, since they might need their awayPaths and type updating if multiple copies are involved.

sidedatacopies: directly fetch copies information from sidedata When using the sidedata mode, we don't need a complicated and expensive `context` object. Instead we directly fetch copies information from the sidedata (through a changelogrevision object).

copies: extract data extraction into a `revinfo` function The function is build once at the beginning of the algorithm and used fetch appropriate information for each revision. This abstracts some implementation details from the main algorithm and will help us to access the data more efficiently in future changesets.
