T894 drops as many uses of "orphan" as possible.
At a compatibility break:
- Drop PCMK_OPT_STOP_ORPHAN_RESOURCES and PCMK_OPT_STOP_ORPHAN_ACTIONS symbols.
- Drop PCMK_OPT_STOP_ORPHAN_RESOURCES and PCMK_OPT_STOP_ORPHAN_ACTIONS from the old_name field of cluster options (replace them with NULL).
- Use an XSL transform to convert "stop-orphan-resources" to "stop-removed-resources" and to convert "stop-orphan-actions" to `"stop-removed-actions"'.
- Drop PCMK_XA_ORPHAN and PCMK_XA_ORPHANED symbols.
- Drop PCMK_XA_ORPHAN and PCMK_XA_ORPHANED from XML outputs, leaving PCMK_XA_REMOVED.
- For text/default-formatted output, replace strings containing "orphan" with the appropriate "removed" string. There should already be COMPAT comments for each of these.
- Drop "orphan" and "orphaned" attributes from XML schemas.
