unshelve: forget unknown files after a partial unshelve This is a follow-up patch to 6957f7b93e03. This allows hg to forget unknown files after a partial unshelve. Differential Revision: https://phab.mercurial-scm.org/D6724

flagutil: move addflagprocessor to the new module (API)

flagutil: move insertflagprocessor to the new module (API)

flagutil: move REVIDX_KNOWN_FLAGS source of truth in flagutil (API) Since REVIDX_KNOWN_FLAGS is "not really a constant" (extension can update it) and python integer,... it needs to be the responsability of a single module and always accessed through the module. We update all the user and move the source of truth in flagutil.

flagutil: move the `flagprocessors` mapping in the new module This module is meant to host most of the flag processing logic. We start with the mapping between flag and processors.

flagutil: create a `mercurial.revlogutils.flagutil` module The flagprocessings logic is duplicated in 2 extra places, and usually in a less robust flavor. This is a maintenance nightmare that I would like to see cleaned up. To do so I am creating a `flagutil` module to move flag processings related code and make it easily reusable by other code.

rawdata: register the method for `ifiledata` The interface have a `revision(..., raw=False)` method so it should get a `rawdata` one. I am not sure why nothing complained about the lack of it earlier.

rawdata: implement the method for `unionrepo` too This is required for all implementations.

rawdata: implement the method for `remotefilelog` too This is needed for all storage implementations.

rawdata: implement `rawdata` for `simplestore` too This is needed for all implementation.

rawdata: forward `rawdata` call on `manifestlog` This needs to be sent to the underlying `revlog` too.

rawdata: implement `rawdata` for `sqlitestore` too This is a different store, it needs it declared.

rawdata: add the method to bundlerevlog The bundlerepo logic has its own `revision` method on its own `revlog` object. We need to "implement" `rawdata` there too.

rawdata: forward the method call on `filelog` object We have a new method, we need to expose it.

rawdata: introduce a `rawdata` method on revlog This method aims at replacing `revision(..., raw=True)` call. The purpose of data returned without and without raw are different enough that having two different method would make sense. This split is motivated by other work aiming at storing data on the side of the main revision of a revlog. Having a cleaner API makes it simpler to add this work. The series following this first changesets is organised as follow: 1) add `rawdata` method everywhere it is useful 2) update all caller 3) implement all `rawdata` method without using `revision` 4) deprecate the `rawdata` parameter of `revision`

revlog: split a `_revisiondata` method to file `revision` job We are about to introduce more public method to access revision data (eg: `rawdata`). revset subclass tend to recursively call `revision` which will create all kind of issue with the coming series. To avoid them we introduce an explicit difference between the internal call and the public all. This will be useful for later work anyway (so the subclass issue is just moving it earlier in the series). I am not sure if the subclass are actually doing something sensible. However, I am certain I don't want to be rabbit holed into figuring it out right now.

continue: added support for transplant This creates a seperate function `continuetransplant()` containing logic for resuming transplant from interrupted state. `continuetransplant()` is then registered as `continuefunc` for state detection API. Results are shown in tests. Differential Revision: https://phab.mercurial-scm.org/D6689

branchmap: explicitly warm+write all subsets of the branchmap caches 'full' claims it will warm all of the caches that are known about, but this was not the case - it did not actually warm the branchmap caches for subsets that we haven't requested, or for subsets that are still considered "valid". By explicitly writing them to disk, we can force the subsets for ex: "served" to be written ("immutable" and "base"), making it cheaper to calculate "served" the next time it needs to be updated.

changectx: extract explicit computechangesetfilesremoved method from context Right now, the logic around changeset centric removed files data are buried into the "changectx" code. We extract this code in a dedicated method (in the scmutil module) for clarity. This clarity will help to explicitly compute and caches these data in the future.

changectx: extract explicit computechangesetfilesadded method from context Right now, the logic around changeset centric added files data are buried into the "changectx" code. We extract this code in a dedicated method (in the scmutil module) for clarity. This clarity will help to explicitly compute and caches these data in the future.

copies: extract an explicit `computechangesetcopie` method from context Right now, the logic around changeset centric copies data are buried into the "changectx" code. We extract this code in a dedicated method (in the copies module) for clarity. This clarity will help to explicitly compute and caches these data in the future.

config: fix fm.data() handling of defaultvalue This is a follow-up patch to rHG51a2e3102db2. This moves `fm.data()` out of the if block in `commands.config()`. Differential Revision: https://phab.mercurial-scm.org/D6720

config: remove pycompat.bytestr() for defaultvalue This is a follow-up patch to 51a2e3102db2. This removes `pycompat.bytestr` to preserve `None` in `commands.config()`. Differential Revision: https://phab.mercurial-scm.org/D6712
