addset: remove `.set()` definition All my friends are dead.

filteredset: remove `.set()` definition All my friends are dead.

baseset: remove `set()` definition All my friends are dead.

abstractsmartset: remove `set()` method definition Now that all usages have been removed, we can drop this not so useful part of the API. We can note that the name was wrong all along...

match: check if an object is a baseset using `isascending` instead of `set` The `set()` method is going away.

getset: check if an object is a baseset using `isascending` instead of `set` The `set()` method is going away.

fullreposet: detect smartset using "isascending" instead of "set" The `.set()` function is going away.

fullreposet: drop custom sets but not smartsets detection All custom classes use by revsets are smartsets now. We drop the special-casing.

addset: drop `.set()` usage during iteration We can use the containment check directly.

baseset: access `_set` directly for containment check The `.set()` method is going away.

baseset: make `_set` a property cache This will remove the need for `baseset.set()`.

graphnode: remove usage of `set()` All smartset classes have fast lookup, so this function will be removed soon.

revset-_hexlist: remove usage of `set()` All smartset classes have fast lookup, so this function will be removed soon.

revset-_intlist: remove usage of `set()` All smartset classes have fast lookup, so this function will be removed soon.

revset-_list: remove usage of `set()` All smartset classes have fast lookup, so this function will be removed soon.

revset-roots: remove usage of `set()` All smartset classes have fast lookup, so this function will be removed soon.

histedit: stabilise the order nodes that are stripped The `nodes` object is a set. We sort it to get stable order. This is going to prevent revsets from getting confused when removing a `.set()` call in `roots`.

revset-origin: remove usage of `set()` All smartset classes have fast lookup, so this function will be removed soon.

revset-last: remove usage of `set()` All smartset classes have fast lookup, so this function will be removed soon.

revset-limit: remove usage of `set()` All smartset classes have fast lookup, so this function will be removed soon.

revset-destination: remove usage of `set()` All smartset classes have fast lookup, so this function will be removed soon.

revset-children: remove usage of `set()` All smartset classes have fast lookup, so this function will be removed soon.

revset-branch: remove usage of `set()` All smartset classes have fast lookup, so this function will be removed soon.

revset-rangeset: remove usage of `set()` All smartset classes have fast lookup, so this function will be removed soon.

revset-only: remove usage of `set()` All smartset classes have fast lookup, so this function will be removed soon.

revset: cache most conditions used in `filter` Except when stated otherwise, the condition used in `smartset.filter` will be cached. A new argument has been introduced to disable that behavior. We use it for filters created from `and` and `sub` operations. This gives massive performance boosts for revsets with expensive conditions. revset: branch(stable) or branch(default) before) wall 4.329070 comb 4.320000 user 4.310000 sys 0.010000 (best of 3) after) wall 2.356451 comb 2.360000 user 2.330000 sys 0.030000 (best of 4) revset: author(mpm) or author(lmoscovicz) before) wall 4.434719 comb 4.440000 user 4.440000 sys 0.000000 (best of 3) after) wall 2.321720 comb 2.320000 user 2.320000 sys 0.000000 (best of 4)

baseset: empty or one-element sets are ascending and descending The empty set is full of interesting properties. In the ordering case, the one element set is too.

filteredset: drop explicit order management Now that all low-level smartset classes have proper ordering and fast iteration management, we can just rely on the subset in filteredset.
