/**
* Handle principal-property-search report
*
* Current implementation runs a full (infinity) propfind, as we have principals only once in the principal collection.
*
* Example from WebDAV ACL rfc 3744:
* REPORT /index.html HTTP/1.1
* Host: www.example.com
* Content-Type: text/xml; charset="utf-8"
* Content-Length: xxxx
* Depth: 0
*
* <?xml version="1.0" encoding="utf-8" ?>
* <D:acl-principal-prop-set xmlns:D="DAV:">
* <D:prop>
* <D:displayname/>
* </D:prop>
* </D:acl-principal-prop-set>
*
* Response is a multistatus as for a propfind. Seems the only diverence is, that prinipals are only returned once
* (even if they exists multiple times), only principals get returned (eg. not the collections they are in) AND the depth 0.
*
* @param string $path
* @param array $options
* @param array &$files
* @param int $user account_id
* @return mixed boolean true on success, false on failure or string with http status (eg. '404 Not Found')
