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.
