Fix PR 56480: PROPFIND walker doesn't encode hrefs properly

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.

The SNI callback already logs a debug message when the vhost
is found or no vhost matches.  Log one when no name is provided

For better compatibility with mod_nss:

* modules/ssl/ssl_engine_config.c (ssl_config_server_new): Default
  sc->enabled to UNSET.

* modules/ssl/ssl_engine_init.c (ssl_init_Module): Only override
  sc->enabled based on the protocol iff sc->enabled is UNSET; allows
  "SSLEngine off" to override the Listen-based default.

grouped with other OCSP ones, nested if turned to a single AND condition).


Remove SSLOCSPUseRequestNonce OpenSSL-0.9.7 requirement (0.9.8 already required by httpd-2.4) and set availability to 2.5-dev until further notice.

cross forks, so child processes have access.

When we need true external access, this is something
that APR shm must provide. We should have no
