*) mod_http2: added support for bootstrapping WebSockets via HTTP/2, as
described in RFC 8441. A new directive 'H2WebSockets on|off' has been
added. The feature is by default not enabled.
As also discussed in the manual, this feature should work for setups
using "ProxyPass backend-url upgrade=websocket" without further changes.
Special server modules for WebSockets will have to be adapted,
most likely, as the handling if IO events is different with HTTP/2.
HTTP/2 WebSockets are supported on platforms with native pipes. This
excludes Windows.
New directive `H2ProxyRequests on|off` to enable handling
of HTTP/2 requests in a forward proxy configuration.
General forward proxying is enabled via `ProxyRequests`. If the
HTTP/2 protocol is also enabled for such a server/host, this new
directive is needed in addition.

*) core/mod_proxy/mod_ssl:
Adding `outgoing` flag to conn_rec, indicating a connection is
initiated by the server to somewhere, in contrast to incoming
connections from clients.
Adding 'ap_ssl_bind_outgoing()` function that marks a connection
as outgoing and is used by mod_proxy instead of the previous
optional function `ssl_engine_set`. This enables other SSL
module to secure proxy connections.
The optional functions `ssl_engine_set`, `ssl_engine_disable` and
`ssl_proxy_enable` are now provided by the core to have backward
compatibility with non-httpd modules that might use them. mod_ssl
itself no longer registers these functions, but keeps them in its
header for backward compatibility.
The core provided optional function wrap any registered function
like it was done for `ssl_is_ssl`.
*core: clarify comments and use hook API better to check for presence of callbacks.

mod_proxy: Fix possible reuse/merging of Proxy(Pass)Match workers. PR 65419.
We can't truncate ProxyMatch's worker name/url to the first '$' substitution
without possibly colliding with other workers. This also makes the matching
done at runtime by ap_proxy_strcmp_ematch() completely pointless.
To fix this and still address r1878467 (i.e. make http://host:port$1 a "valid"
URL), we need to remove '$' substitutions from the :port part of the URL only
since it's allowed anywhere else by apr_uri_parse().
So let's strip them before apr_uri_parse() and prepend them back in the path
before apr_uri_unparse() to restore the original URL. Non-matchable workers are
not concerned so ap_proxy_define_worker() is made a local helper (w/o the ap_
prefix) which takes "matchable" as argument and can then be called by both
ap_proxy_define_[match_]worker() functions.
mod_proxy: Follow up to r1891206: fix UDS scheme.
mod_proxy: Avoid confusion of prefix/regex matching workers at loading. PR 65429.
ap_proxy_get_worker() needs to know whether it should lookup for prefix or
match or both matching workers, depending on the context.
For instance <Proxy[Match]> or ProxyPass[Match] directives need to lookup for
an existing worker with the same type as the directive (*Match or not), because
they will define one with that matching type if none exists.
On the contrary, "ProxySet <url>" at load time or ap_proxy_pre_request() at run
time need to find a worker matching an url whether it's by prefix or by regex.
So this commit adds ap_proxy_get_worker_ex() which takes a bitmask for the
matching type and calls it appropriately where needed.
For consistency, ap_proxy_define_worker_ex() is also added, using the same
bitmask flags, deprecating ap_proxy_define_match_worker().
Follow up to r1891206.
