rust-update: handle SIGINT from long-running update threads

The current code does not respond to ^C until after the Rust bit is finished
doing its work. This is expected, since Rust holds the GIL for the duration
of the call and does not call `PyErr_CheckSignals`. Freeing the GIL to do our
work does not really improve anything since the Rust threads are still going,
and the only way of cancelling a thread is by making it cooperate.

So we do the following:
	- remember the SIGINT handler in hg-cpython and reset it after the call
	  into core (see inline comment in `update.rs` about this)
	- make all update threads watch for a global `AtomicBool` being `true`,
	  and if so stop their work
	- reset the global bool and exit early (i.e. before writing the dirstate)
	- raise SIGINT from `hg-cpython` if update returns `InterruptReceived`
