Reverts r1529559 partially (specifically the dav_xml_escape_uri) bit.
Reverts r1531505 entirely.

* modules/dav/main/mod_dav.c
  (dav_xml_escape_uri): Revert the piece of r1529559 that removes the URI
    escaping from this function.

* modules/dav/main/props.c
  (dav_do_prop_subreq): Escape the URI before doing a sub request with it.
    This resolves some properties like getcontenttype from failing to be
    returned for files that contain characters that require encoding in their
    path.

* modules/dav/main/mod_dav.h
  (dav_resource): Note the inconsistency in the documentation.

* modules/dav/fs/repos.c
  (dav_fs_get_resource): Don't use the unparsed_uri to set the uri field of
    the resource.  This is the correct fix for the double encoding in mod_dav_fs
    that led to the dav_xml_escape_uri() change and r1531505.
  (dav_fs_walker, dav_fs_append_uri): Revert r1531505 changes.

Forward local IP address as a custom request attribute
like we already do for the remote port.

Both were forgotten in the original AJP 13 spec
but are needed by the Servlet spec. Until now,
Tomcat simply returns for getLocalAddr() the same as
for getLocalName().

The next round of Tomcat releases will look for the
optional new request attribute.

See also Tomcat BZ 56661.
