pyoxidizer: add the user site to `sys.path` on macOS This allows 3rd party extensions that are installed with `pip` to be picked up, similar to what we do on Windows. PyOxidizer has a bug that prevents this from working without this extra help (see 95af358fcdfe), though it appears there's another wrinkle here with `sys._framework` too. I needed this to see if the problem[1] loading the keyring extension on Windows also occurs on macOS (it doesn't).

pyoxidizer: don't use in-memory for resources on macOS When trying to debug something else on macOS, pyoxidized builds were failing with the following message about pywatchman (and then cext.base85 when I commented out pywatchman): "cannot be loaded from memory but memory loading required" I don't have any immediate plans to do more work on macOS, but maybe this will save someone else time debugging this.

chistedit: rename a confusingly named variable I would expect `ctxs` contain instances of some class from the `context` module but it actually contains instances of `histeditrule`. Differential Revision: https://phab.mercurial-scm.org/D11653

chistedit: remove some local variable and access state on self instead Now that we've replaced the state dict by a class, some of the local variables that just do `foo = self.foo` seem unnecessary. Differential Revision: https://phab.mercurial-scm.org/D11652
