rhg: add exit code to HgError::Abort()
My previous attempts to have rhg end with correct exit code was more of bug
hunting. I found cases which were failing and fixed them. But as one might
expect, more tests started failing.
Let's add exit code `HgError::Abort()` and make it users explicitly tell what
exit code they want.
