http: remove "struct HTTP"
It is not actually used anymore and only contained a dummy struct field.

connection: shutdown TLS (for FTP) better
This adds connection shutdown infrastructure and first use for FTP. FTP
data connections, when not encountering an error, are now shut down in a
blocking way with a 2sec timeout.

    - add cfilter `Curl_cft_shutdown` callback
    - keep a shutdown start timestamp and timeout at connectdata
    - provide shutdown timeout default and member in
      `data->set.shutdowntimeout`.
    - provide methods for starting, interrogating and clearing
      shutdown timers
    - provide `Curl_conn_shutdown_blocking()` to shutdown the
      `sockindex` filter chain in a blocking way. Use that in FTP.
    - add `Curl_conn_cf_poll()` to wait for socket events during
      shutdown of a connection filter chain.
      This gets the monitoring sockets and events via the filters
      "adjust_pollset()" methods. This gives correct behaviour when
      shutting down a TLS connection through a HTTP/2 proxy.
    - Implement shutdown for all socket filters
      - for HTTP/2 and h2 proxying to send GOAWAY
      - for TLS backends to the best of their capabilities
      - for tcp socket filter to make a final, nonblocking
        receive to avoid unwanted RST states
    - add shutdown forwarding to happy eyeballers and
      https connect ballers when applicable.

http/2, http/3: decouple stream state from easy handle
- add `Curl_hash_offt` as hashmap between a `curl_off_t` and
  an object. Use this in h2+h3 connection filters to associate
  `data->id` with the internal stream state.
- changed implementations of all affected connection filters
- removed `h2_ctx*` and `h3_ctx*` from `struct HTTP` and thus
  the easy handle
- solves the problem of attaching "foreign protocol" easy handles
  during connection shutdown

Test 1616 verifies the new hash functions.

build: prefer USE_IPV6 macro internally (was: ENABLE_IPV6)
Before this patch, two macros were used to guard IPv6 features in curl
sources: `ENABLE_IPV6` and `USE_IPV6`. This patch makes the source use
the latter for consistency with other similar switches.

`-DENABLE_IPV6` remains accepted for compatibility as a synonym for
`-DUSE_IPV6`, when passed to the compiler.

`ENABLE_IPV6` also remains the name of the CMake and `Makefile.vc`
options to control this feature.

9287563e86 vquic: use new curl_int64_t type
- add curl_int64_t signed 64-bit type for lib use

- define CURL_PRId64, CURL_PRIu64 format ids

- use curl_int64_t in vquic

curl_int64_t signed complements the existing curl_uint64_t unsigned.

Note that `curl_int64_t` and `int64_t` are assignable from each other
but not identical. Some platforms with 64 long type defint int64_t as
"long long" (staring at macOS) which messes up things like pointers and
format identifiers.

OpenSSL QUIC: adapt to v3.3.x
- set our idle timeout as transport parameter
- query negotiated idle timeout for connection alive checks
- query number of available bidi streams on a connection
- use write_ex2 with SSL_WRITE_FLAG_CONCLUDE to signal
  EOF on last chunk write, so stream close does not
  require an additional QUIC packet

http3: initial support for OpenSSL 3.2 QUIC stack
- HTTP/3 for curl using OpenSSL's own QUIC stack together
  with nghttp3
- configure with `--with-openssl-quic` to enable curl to
  build this. This requires the nghttp3 library
- implementation with the following restrictions:
  * macOS has to use an unconnected UDP socket due to an
    issue in OpenSSL's datagram implementation
    See https://github.com/openssl/openssl/issues/23251
    This makes connections to non-reponsive servers hang.
  * GET requests will send the indicator that they have
    no body in a separate QUIC packet. This may result
    in processing delays or Transfer-Encodings on proxied
    requests
  * uploads that encounter blocks will use 100% cpu as
    detection of these flow control issue is not working
    (we have not figured out to pry that from OpenSSL).
