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

$ hg init a
$ cd a
$ touch a; hg commit -qAm_
$ hg bookmark $(for i in $($TESTDIR/seq.py 0 20); do echo b$i; done)
$ hg clone . ../b -q
$ cd ../b
Checking that when lookup multiple bookmarks in one go, if one of them
fails (thus causing the sshpeer to be stopped), the errors from the
further lookups don't result in tracebacks.
$ hg pull -r b0 -r nosuchbookmark $(for i in $($TESTDIR/seq.py 1 20); do echo -r b$i; done) -e "\"$PYTHON\" \"$TESTDIR/dummyssh\"" ssh://user@dummy/$(pwd)/../a
pulling from ssh://user@dummy/$TESTTMP/b/../a
abort: unknown revision 'nosuchbookmark'
