rhg: Move `Repo` object creation into `main()`
… rather than in each sub-command that needs a local repository.
This will allow accessing e.g. `.hg/blackbox.log` before dispatching
to sub-commands.

rhg: Group values passed to every sub-command into a struct
The set of which values this is is evidently not stable yet,
so this will make changes easier. Also it is growing, and the function
signatures are getting out hand.

copies-rust: send PyBytes values back be dropped ino the parent thread
… instead of acquiring the GIL in the Rust thread in the Drop impl
This commit is based on the premise that crossbeam-channel
with unbounded send and non-blocking receive is faster than
a contended GIL, but that remains to be measured.

copies-rust: introduce PyBytesWithData to reduce GIL requirement

Simon Sapin <simon.sapin@octobus.net> [Wed, 06 Jan 2021 14:09:01 +0100] rev 46627
copies-rust: move CPU-heavy Rust processing into a child thread
… that runs in parallel with the parent thread fetching data.
This can be disabled through a new config. CLI example:
hg --config=devel.copy-tracing.multi-thread=no
For now both threads use the GIL, later commits will reduce this.

copies-rust: split up combine_changeset_copies function into a struct
… such that each iteration of its former loop is now a method call,
with the caller driving the loop.
This entirely removes the need for the `DataHolder` hack:
the method now takes a `ChangedFiles<'_>` parameter that borrows
a bytes buffer that can be owned by the caller’s stack frame,
just for the duration of that call.
