hgit: make sure repository is local before checking for store type httppeer (and maybe others too) does not have a store attribute. This was causing `hg pull` being broken on a hg repository when the extension is enabled. localpeer.local() does returns a non-None value but I am not sure if it matters.

hg-core: add function timing information This change makes use of the newly added logging infrastructure to trace the execution time of some important calls. This approach is very much complementary to using a profiler and will not guard against out-of-order execution or other kinds of compiler optimizations. That said, it is useful to get a rough high-level idea of where time is spent. Differential Revision: https://phab.mercurial-scm.org/D8253

rust: add logging utils This change adds the `log` crate, the community-approved logging facade backed by Rust core developers as well as the logging-consumer crate `simple_logger` to build a foundation for logging from Rust. Using this setup allows us to choose how to log depending on the way `hg-core` is used: if it's within the context of `hg-cpython`, we might not want to use it the same way as with a direct cli for example.

rust-status: traverse working directory in parallel Using `rayon` for this task ensures that we are using the same work-stealing threadpool for everything. This change introduces `crossbeam` as an explicit dependency, although it is already a dependency of `rayon`. It provides better structures for multi-threaded tasks than the stdlib.
