obsstore: rename precursors into predecessors Use util.nouideprecwarn because obsstore doesn't have easy access to an ui object. The renaming is done according to https://www.mercurial-scm.org/wiki/CEDVocabulary. Differential Revision: https://phab.mercurial-scm.org/D245

obsolete: rename _addprecursors into _addpredecessors Use util.nouideprecwarn because _addpredecessors doesn't have easy access to an ui object. The renaming is done according to https://www.mercurial-scm.org/wiki/CEDVocabulary. Differential Revision: https://phab.mercurial-scm.org/D244

obsmarker: rename precnode into prednode Rename prednode (predecessors node) into precnode (precursors node) in markers class. Use util.nouideprecwarn because markers doesn't have easy access to an ui object. The renaming is done according to https://www.mercurial-scm.org/wiki/CEDVocabulary.

context: rename troubled into isunstable As we changed the meaning of unstable between the old vocabulary and the new one, we can't reuse the unstable method name at the risk of breaking extensions calling unstable and getting a wrong result. Instead rename troubled into isunstable so extensions will continue to work. The renaming is done according to https://www.mercurial-scm.org/wiki/CEDVocabulary. Differential Revision: https://phab.mercurial-scm.org/D242

context: rename bumped into phasedivergent Rename bumped context method into phasedivergent and add a deprecation warning on bumped. Only update all callers to keep the patch straightforward. The renaming is done according to https://www.mercurial-scm.org/wiki/CEDVocabulary. Differential Revision: https://phab.mercurial-scm.org/D241

context: rename divergent into contentdivergent Rename divergent context method into contentdivergent and add a deprecation warning on divergent. Only update all callers to keep the patch straightforward. The renaming is done according to https://www.mercurial-scm.org/wiki/CEDVocabulary. Differential Revision: https://phab.mercurial-scm.org/D240

context: rename unstable into orphan Rename unstable context method into orphan and add a deprecation warning on unstable. Only update all callers to keep the patch straightforward. The renaming is done according to https://www.mercurial-scm.org/wiki/CEDVocabulary. Differential Revision: https://phab.mercurial-scm.org/D239

context: rename troubles into instabilities Rename troubles context method into instabilities. Copy the old troubles method and add a deprecation warning. This way extensions calling troubles will see the deprecation warning but will not break due to new return values. The renaming is done according to https://www.mercurial-scm.org/wiki/CEDVocabulary.

repair: move manifest strip to a separate function This moves manifest stripping to a separate function so implementations of the manifest that don't support stripping can replace this function with a no-op. I considered adding a strip api to the manifestlog, so other implementations could make it a no-op there, but it seems like strip might be unique to the revlog implementation, and therefore shouldn't be present on the generic api.

repair: refactor broken linkrev collection This refactors broken linkrev collection such that manifest collection is in a separate function. This allows extensions to replace the manifest collection with a non-revlog oriented version. I considered moving the collect changes function onto the manifestlog itself, so it would be behind the abstraction, but since the store we're building doesn't even have the concept of strip, embeding that concept in the manifestlog api seemed odd.
