stablerange: move revs computation within the main class We still need to compute the revision withing a range when we slice a merge. This is the last large logic that remains in the individual class and we migrate is on the main class.

stablerange: minor method reorders on the main class We put the public method first for clarify.

stablerange: drop "key" and "id" logic form the class We can restrict to the bare minimun for equality and hashing now.

stablerange: drop length from the class There is not remaining user.

stablerange: drop _depth Nothing uses it anymore.

stablerange: drop __repr__ IT was used for debug and the class is on it way out.

stablerange: drop the subranges method on the small class Nobody use it anymore.

stablerange: use subranges from the main class in subrangesclosure This is the last method used on the class.

stablerange: use subranges from the main class in _obshashrange This is the last method used on the class.

stablerange: use subranges from the main class in findrangemissing This is the last method used on the class.

stablerange: make sure nobody use '.depth' anymore

stablerange: use depthrevs in range slicing We stop using the property from the class to get us closer to tuple.

stablerange: use depthrevs in debugstablerange We stop using the property from the class to get us closer to tuple.

stablerange: use rangelength inside the class itself We stop using the building '__len__' this get use closer to be able to use a tuple.

stablerange: use rangelength in '_slicesatrange' We stop using the building '__len__' this get use closer to be able to use a tuple.

stablerange: use rangelength in '_slicepoint' We stop using the building '__len__' this get use closer to be able to use a tuple.
