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 Differential Revision: https://phab.mercurial-scm.org/D10239

rhg: add support for detailed exit code for ConfigParseError This patch adds basic support for detailed exit code to rhg with support for ConfigParseError.
