rhg: Initial support for the 'status' command

Only comparing the working directory with its first parent revision
is supported. The core logic of dirstate handling and `stat`’ing files
was already in `hg-core` supporting Python-based hg with Rust extensions,
so this is mostly plumbing to rhg’s CLI.

For now the command is experimental and disabled by default,
since it has some bugs that causes a number of tests to fail.
These failures can be seen with:

  tests/run-tests.py --rhg --extra-config-opt rhg.status=true
