[PATCH] D31163: Implement Pp0156r2 "Variadic Lock Guard, version 5"

[Marshall Clow via Phabricator via cfe-commits]

mclow.lists created this revision.

WG21 has decided that the ABI-breaking `lock_guard` proposal that we (@EricWF) implemented (and hid behind an ABI-break macro) is not the way to go. Instead, we're introducing a new class, `scoped_lock`, which is variadic, and leaving `lock_guard` as non-variadic.

So, delete Eric's work, nuke the ABI macro, and implement the non-ABI breaking stuff.

While I'm in the neighborhood, implement the mutex-ey parts of P0433: "Deduction guides for the standard library". This bit has the guides for `lock_guard`, `scoped_lock`, `unique_lock`, and `shared_lock`.

Note: If you're using the variadic version of `lock_guard`, then this is a breaking change.  Good news is that you just switch to using `scoped_lock`, and everything works the same.
