strip: move into core As discussed at the 5.2 sprint, replace strip extension by a core command, debugstrip. Obviously, the extension stays for backwards compatibility. As an implementation note, I moved the strip file as is into core, which is not done elsewhere, AFAIK. I could have inlined it into debugcommands, but that doesn't sound great.

This subtle issue was caught by pytype, which correctly identified the return value as List[Optional[Tuple]] because of this possibility. Differential Revision: https://phab.mercurial-scm.org/D9279

rust-status: don't bubble up os errors, translate them to bad matches In the rare cases when either the OS/filesystem throws an error on an otherwise valid action, or because a path is not representable on the filesystem, or because of concurrent actions in the filesystem, we want to warn the user about said path instead of bubbling up the error, causing an exception to be raised in the Python layer.
