bookmarks: jettison bmstore's write() method per deprecation policy

merge with stable

deprecation: gate deprecation warning behind devel configuration Regular users are not supposed to be exposed to the API deprecation warnings. We now only issue them when the developper warnings are enabled.

crecord: update downarrowshiftevent() docstring, remove todo The phrasing is mostly taken from uparrowshiftevent().

crecord: remove things that don't happen in functions from their docstrings Scrolling screen is currently done in a different place. The things that had been described in the docstrings may still happen, but the functions touched by this patch don't do any scrolling, they only set self.currentselecteditem and nothing more.

crecord: remove skipfolded keyword argument from patchnode.previtem() It wasn't used, it wasn't implemented. Probably was a copy-paste bonus from patchnode.nextitem()

crecord: update a copy-pasted comment in downarrowshiftevent()

crecord: drop the version condition for amend The UI is now shipped in core, amend feature is always available.

crecord: add/remove blank lines (coding style)

localrepo: jettison parents() method per deprecation policy (API)

revset: define _parsealias() in _aliasrules class It's short. It doesn't make sense to define _parsealias() outside of the class.

revset: factor out common parsing function

revset: inline _tokenizealias() into _parsealias() This helps factoring out common part between _parsealias() and parse().

store: treat range as a generator instead of a list for py3 compat

ui: add new config option for help text width Before this patch, when printing help text using `hg help`, or `hg log -h`, the output will wrap at 78 chars even if the user has a bigger terminal width and there is no config option to change it, making the experience different from the commonly used `man` tool. This patch introduces a new config option `ui.textwidth`, which replaces the hardcoded number. It's set to 78 by default to maintain compatibility. When set to 0, `hg help` will behave more like `man`.

tests: test histedit base command plan help

largefiles: makes verify batching stat calls to remote Instead of sending stat calls for each files separately, it sends one batch call with stat invocations for all files.

largefiles: change basestore._verifyfile to take list of files to check Makes it easier to use batch stat calls in remotestore to decrease number of round trips.

bookmarks: properly invalidate volatile sets when writing bookmarks This corrects a regression introduced during the 3.7 cycle, but which went undetected due to the surviving-but-deprecated write() method on bmstore.

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.

keyword: replace use of _filerev with _filenode To be independent of rev numbers. Analogous to ba8257cb53e8.
