Backwards Compatibility Changes

• chg worker processes will now correctly load per-repository configuration

  • when given a both a relative --repository path and an alternate working directory via --cwd. A side-effect of this change is that these workers will now return an error if hg cannot find the current working directory, even when a different directory is specified via --cwd.

• phase: rename the requirement for internal-phase from internal-phase to use-internal-phase (see 74fb1842f8b962cf03d7cd5b841dbcf2ae065587)
