hgcli: add stub PyOxidizer project
Using commit c772a1379c3026314eda1c8ea244b86c0658951d of
PyOxidizer, I ran `pyoxidizer init-rust-project hgcli` to
create a stub Rust project. The only modifications I made from
what that command produced are:
* Update location of pyembed crate to PyOxidizer's Git repository.
* Removed some trailing whitespace from pyoxidizer.bzl
* Added auto-generated Cargo.lock file
Subsequent commits will modify the stub project to Mercurial's
needs.

'''measure performance of Mercurial commands Using ``hgperf`` instead of ``hg`` measures performance of the target Mercurial command. For example, the execution below measures performance of :hg:`heads --topo`:: $ hgperf heads --topo All command output via ``ui`` is suppressed, and just measurement result is displayed: see also "perf" extension in "contrib". Costs of processing before dispatching to the command function like below are not measured:: - parsing command line (e.g. option validity check) - reading configuration files in But ``pre-`` and ``post-`` hook invocation for the target command is measured, even though these are invoked before or after dispatching to the command function, because these may be required to repeat execution of the target command correctly.
