davical/inc/caldav-REPORT-principal-match.php
Florian Schlichting a7ba436f2f advertise support for principal-match REPORT
and a few more bits inspired by CalDAV/aclreports.xml:
    - strict Depth header checking
    - principal-match: match on dav_name if not $match_self
    - principal-match can "alternatively" return resources in a collection
      that belong to a principal, like a user's calendars when we query
      the principal URI
