gnutls: repair the build with CURL_DISABLE_PROXY
`http_proxy`/`proxy_ssl`/`tunnel_proxy` will not be available in `conn`
if `CURL_DISABLE_PROXY` is enabled.  Repair the build with that

http2: close the http2 connection when no more requests may be sent
Well-behaving HTTP2 servers send two GOAWAY messages. The first
message is a warning that indicates that the server is going to
stop accepting streams. The second one actually closes the stream.

nghttp2 reports this state (and the other state of no more stream
identifiers) via the call nghttp2_session_check_request_allowed().
In this state the client should not create more streams on the
session (tcp connection), and in curl this means that the server
has requested that the connection is closed.

It would be also be possible to put the connclose() call into the
on_http2_frame_recv() function that triggers on the GOAWAY message.

This fixes a bug seen when the client sees the following sequence of
frames:

// advisory GOAWAY
HTTP2 GOAWAY [stream-id = 0, promised-stream-id = -1]
... some additional frames

// final GOAWAY
HTTP2 GOAWAY [stream-id = 0, promised-stream-id = N ]

Before this change, curl will attempt to reuse the connection even
after the last stream, will encounter this error:

* Found bundle for host localhost: 0x5595f0a694e0 [can multiplex]
* Re-using existing connection! (#0) with host localhost
* Connected to localhost (::1) port 10443 (#0)
* Using Stream ID: 9 (easy handle 0x5595f0a72e30)
> GET /index.html?5 HTTP/2
> Host: localhost:10443
> user-agent: curl/7.68.0
> accept: */*
>
* stopped the pause stream!
* Connection #0 to host localhost left intact
curl: (16) Error in the HTTP2 framing layer

This error may posion the connection cache, causing future requests
which resolve to the same curl connection to go through the same error
path.

url: silence MSVC warning
Since commit f3d501dc67, if proxy support is disabled, MSVC warns:
url.c : warning C4701: potentially uninitialized local variable
'hostaddr' used
url.c : error C4703: potentially uninitialized local pointer variable
'hostaddr' used

That could actually only happen if both `conn->bits.proxy` and
`CURL_DISABLE_PROXY` were enabled.
Initialize it to NULL to silence the warning.

abbc5d6044 openssl: Don't ignore CA paths when using Windows CA store
This commit changes the behavior of CURLSSLOPT_NATIVE_CA so that it does
not override CURLOPT_CAINFO / CURLOPT_CAPATH, or the hardcoded default
locations. Instead the CA store can now be used at the same time.

The change is due to the impending release. The issue is still being
discussed. The behavior of CURLSSLOPT_NATIVE_CA is subject to change and
is now documented as experimental.

http: move header storage to Curl_easy from connectdata
Since the connection can be used by many independent requests (using
HTTP/2 or HTTP/3), things like user-agent and other transfer-specific
data MUST NOT be kept connection oriented as it could lead to requests
getting the wrong string for their requests. This struct data was
lingering like this due to old HTTP1 legacy thinking where it didn't
mattered..

openssl: set FLAG_TRUSTED_FIRST unconditionally

patching, it is possible for macro X509_V_FLAG_NO_ALT_CHAINS to be
defined, while the previous behavior of openssl to not look at trusted
chains first, remains.

Fix it: ensure X509_V_FLAG_TRUSTED_FIRST is always set, do not try to
probe for the behavior of openssl based on the existence ofmacros.
