http2: upgrade tests and add fix for non-existing stream
- check in h2 filter recv that stream actually exists
  and return error if not
- add test for parallel, extreme h2 upgrades that fail if
  connections get reused before fully switched
- add h2 upgrade upload test just for completeness

Closes #11563

http2: fix EOF handling on uploads with auth negotiation
- doing a POST with `--digest` does an override on the initial request
  with `Content-Length: 0`, but the http2 filter was unaware of that
  and expected the originally request body. It did therefore not
  send a final DATA frame with EOF flag to the server.
- The fix overrides any initial notion of post size when the `done_send`
  event is triggered by the transfer loop, leading to the EOF that
  is necessary.
- refs #11194. The fault did not happen in testing, as Apache httpd
  never tries to read the request body of the initial request,
  sends the 401 reply and closes the stream. The server used in the
  reported issue however tried to read the EOF and timed out on the
  request.

http/2: unstick uploads
- refs #11157 and #11175 where uploads get stuck or lead to RST streams
- fixes our h2 send behaviour to continue sending in the nghttp2 session
  as long as it wants to. This will empty our send buffer as long as
  the remote stream/connection window allows.
- in case the window is exhausted, the data remaining in the send buffer
  will wait for a WINDOW_UPDATE from the server. Which is a socket event
  that engages our transfer loop again
- the problem in the issue was that we did not exhaust the window, but
  left data in the sendbuffer and no further socket events did happen.
  The server was just waiting for us to send more.
- relatedly, there was an issue fixed that closing a stream with KEEP_HOLD
  set kept the transfer from shutting down - as it should have - leading
  to a timeout.

Closes #11176

http2: upload improvements
Make send buffer smaller to have progress and "upload done" reporting
closer to reality. Fix handling of send "drain" condition to no longer
trigger once the transfer loop reports it is done sending. Also do not
trigger the send "drain" on RST streams.

Background:
- a upload stall was reported in #11157 that timed out
- test_07_33a reproduces a problem with such a stall if the
  server 404s the request and RSTs the stream.
- test_07_33b verifies a successful PUT, using the parameters
  from #11157 and checks success

proxy: http2 proxy tunnel implementation
- currently only on debug build and when env variable
  CURL_PROXY_TUNNEL_H2 is present.
- will ALPN negotiate with the proxy server and switch
  tunnel filter based on the protocol negotiated.
- http/1.1 tunnel code moved into cf-h1-proxy.[ch]
- http/2 tunnel code implemented in cf-h2-proxy.[ch]
- tunnel start and ALPN set remains in http_proxy.c
- moving all haproxy related code into cf-haproxy.[ch]

VTLS changes
- SSL filters rely solely on the "alpn" specification they
  are created with and no longer check conn->bits.tls_enable_alpn.
- checks on which ALPN specification to use (or none at all) are
  done in vtls.c when creating the filter.

Testing
- added a nghttpx forward proxy to the pytest setup that
  speaks HTTP/2 and forwards all requests to the Apache httpd
  forward proxy server.
- extending test coverage in test_10 cases
- adding proxy tests for direct/tunnel h1/h2 use of basic auth.
- adding test for http/1.1 and h2 proxy tunneling to pytest

http3: improvements across backends
- ngtcp2: using bufq for recv stream data
- internal stream_ctx instead of `struct HTTP` members
  for quiche, ngtcp2 and msh3
- no more QUIC related members in `struct HTTP`
- experimental use of recvmmsg(), disabled by default
  - testing on my old debian box shows no throughput improvements.
  - leaving it in, but disabled, for future revisit
- vquic: common UDP receive code for ngtcp2 and quiche
- vquic: common UDP send code for ngtcp2 and quiche
- added pytest skips for known msh3 failures
- fix unit2601 to survive torture testing
- quiche: using latest `master` from quiche and enabling large download
  tests, now that key change is supported
- fixing test_07_21 where retry handling of starting a stream
  was faulty
- msh3: use bufq for recv buffering headers and data
- msh3: replace fprintf debug logging with LOG_CF where possible
- msh3: force QUIC expire timers on recv/send to have more than
  1 request per second served

http2: flow control and buffer improvements
- use bufq for send/receive of network data
- usd bufq for send/receive of stream data
- use HTTP/2 flow control with no-auto updates to control the
  amount of data we are buffering for a stream
  HTTP/2 stream window set to 128K after local tests, defined
  code constant for now
- elminiating PAUSEing nghttp2 processing when receiving data
  since a stream can now take in all DATA nghttp2 forwards

Improved scorecard and adjuste http2 stream window sizes
- scorecard improved output formatting and options default
- scorecard now also benchmarks small requests / second

pytest: improvements for suitable curl and error output
- will check built curl for http and https support and
  skip all tests if not there
- will dump stdout/stderr/trace output on errored responses

tests/http: add pytest to GHA and improve tests
- added to: ngtcp2-quictls, ngtcp2-gnutls and the linux varians
  quiche, bearssl, libressl, mbedtls, openssl3, rustls
- added disabled in ngtcp2-wolfssl due to weird SSL_connect() errors
  not reproducable locally

Improvements on pytest:

-  handling of systems with nghttpx in $PATH
   - configure will seach $PATH got nghttpx used in pytest
   - pytest fixes for managing nghttpx without h3 support
   - ngtcp2-wolfssl: use a fully enabled wolfssl build

- lower parallel count for http/1.1 tests, since we do not
   want to test excessive connections.
- check built curl for HTTPS-proxy support in proxy tests
- bearssl does not like one of our critical cert extensions, making
  it non-critical now
- bearssl is too slow for test_12, skipping
- making sure we do h3 tests only when curl and server support is there

tests: rename tests/tests-httpd to tests/http
- httpd is only one server we test with
 - the suite coveres the HTTP protocol in general where
   the default test cases need a more beefy environment
