Fix PR 55397: dav_resource->uri treated as an unparsed uri.

The change made for PR 54611 caused this field to be treated as
unescaped.  mod_dav_svn however, provided escaped URIs.  Essentially
breaking support for paths with non-URI safe characters in SVN.

Adjust the code so that dav_resource->uri is assumed to be escaped and
adjust mod_dav_fs so that it uses escaped URIs in this field.

* modules/dav/fs/repos.c
  (dav_fs_get_resource): Use the unparsed_uri to contruct the resource uri.

* modules/dav/main/mod_dav.c
  (dav_xml_escape_uri): Do not uri escape, just handle xml escaping.
  (dav_created): Assume that locn if provided is escaped.
  (dav_method_copymove, dav_method_bind): Use the unparsed_uri on the request
    when calling dav_created() to adjust to locn assuming it is escaped.

* modules/dav/main/mod_dav.h
  (dav_resource): Document that uri is escaped.


Followup to r1529559: mod_dav_fs: Fix encoding of hrefs in PROPFIND response.

Previous commit missed encoding the names of the children of the PROPFIND
request when the depth wasn't 0.

* modules/dav/fs/repos.c
  (dav_fs_append_uri): New function
  (dav_fs_walker): Use dav_fs_append_uri() and adjust length calculations to
    use the encoded length.

mod_dav: Fix PR 55306.

Makes mod_dav no longer require that the lock token be provided when the
source of a COPY is locked.  The prior behavior was in violating of
RFC 4918 which says that the lock token is only required on resources
that may be modified by the method.

* modules/dav/main/mod_dav.h
  (DAV_VALIDATE_NO_MODIFY): New flag to be passed to dav_validate_* functions.

* modules/dav/main/mod_dav.c
  (dav_method_copymove): Use the new flag when calling dav_validate_request()
    on the COPY source.

* modules/dav/main/util.c
  (dav_validate_resource_state): Use the flag to decide to ignore if the lock
    token is not provided.

Interpolation worked within the scheme portion of URLs for
ProxyPass and ProxyPassReverse until a fix to apr_uri_parse()
in APR-Util 1.5.2 closed the hole that had previously allowed
the necessary {} characters within the scheme.

Lack of support for interpolation within the scheme will be a
permanent limitation.

The mod_proxy documentation is updated to provide an alternate
configuration solution.
