By moving it to the single function that uses it, we eliminate a
#cfg.

perf: do not import util.queue
This was added by
af25237be091. But util.queue is not a module and is not
importable. I guess it wasn't noticed because of demandimport.

rust: move Cargo.lock
If you do a `cargo build` in rust/, Cargo will create rust/Cargo.lock.
Furthermore, the previous rust/hgcli/Cargo.lock appears to not even be
consulted because the auto-generated rust/Cargo.lock varied from
rust/hgcli/Cargo.lock.
This commit moves Cargo.lock to where Cargo expects it to be.
While we're here, bump the version of libc to the latest available.

perf: add threading capability to perfbdiff
Since we are releasing the GIL during diffing, it is interesting to see how a
thread pool would perform on diffing. We add a new `--threads` argument to
commands. Synchronizing the thread pool is a bit complex because we want to be
able to reuse it from one run to another.
On my computer (i7 with 4 cores + hyperthreading), I get the following data for
about 12000 revisions:

Compared to the feature disabled (threads=0), the overhead is negligible with
the threading code (threads=1), and the gain is already 48% with two threads.
