Limit the number of http headers when receiving the http response

Change introduces a default limit on HTTP headers we expect to receive
from server to 256. If limit is exceeded http client library indicates
HTTP_R_RESPONSE_TOO_MANY_HDRLINES error. Application can use
OSSL_HTTP_REQ_CTX_set_max_response_hdr_lines() to change default.
Setting limit to 0 implies no limit (current behavior).

Fixes #22264

HTTP: Implement persistent connections (keep-alive)

Both at API and at CLI level (for the CMP app only, so far)
there is a new parameter/option: keep_alive.
* 0 means HTTP connections are not kept open after
receiving a response, which is the default behavior for HTTP 1.0.
* 1 means that persistent connections are requested.
* 2 means that persistent connections are required, i.e.,
in case the server does not grant them an error occurs.

For the CMP app the default value is 1, which means preferring to keep
the connection open. For all other internal uses of the HTTP client
(fetching an OCSP response, a cert, or a CRL) it does not matter
because these operations just take one round trip.

If the client application requested or required a persistent connection
and this was granted by the server, it can keep the OSSL_HTTP_REQ_CTX *
as long as it wants to send further requests and OSSL_HTTP_is_alive()
returns nonzero,
else it should call OSSL_HTTP_REQ_CTX_free() or OSSL_HTTP_close().
In case the client application keeps the OSSL_HTTP_REQ_CTX *
but the connection then dies for any reason at the server side, it will
notice this obtaining an I/O error when trying to send the next request.

This requires extending the HTTP header parsing and
rearranging the high-level HTTP client API. In particular:
* Split the monolithic OSSL_HTTP_transfer() into OSSL_HTTP_open(),
OSSL_HTTP_set_request(), a lean OSSL_HTTP_transfer(), and OSSL_HTTP_close().
* Split the timeout functionality accordingly and improve default behavior.
* Extract part of OSSL_HTTP_REQ_CTX_new() to OSSL_HTTP_REQ_CTX_set_expected().
* Extend struct ossl_http_req_ctx_st accordingly.

Use the new feature for the CMP client, which requires extending
related transaction management of CMP client and test server.

Update the documentation and extend the tests accordingly.

Also improve the generic HTTP client w.r.t. proxy and no_proxy options.

Certificate Management Protocol (CMP, RFC 4210) extension to OpenSSL
Also includes CRMF (RFC 4211) and HTTP transfer (RFC 6712).
Adds the CMP and CRMF API to libcrypto and the "cmp" app to the CLI.
Adds extensive documentation and tests.

Generalize the HTTP client so far implemented mostly in crypto/ocsp/ocsp_ht.c
The new client has become an independent libcrpyto module in crypto/http/ and
* can handle any types of requests and responses (ASN.1-encoded and plain)
* does not include potentially busy loops when waiting for responses but
* makes use of a new timeout mechanism integrated with socket-based BIO
* supports the use of HTTP proxies and TLS, including HTTPS over proxies
* supports HTTP redirection via codes 301 and 302 for GET requests
* returns more useful diagnostics in various error situations
Also adapts - and strongly simplifies - hitherto uses of HTTP in crypto/ocsp/,
crypto/x509/x_all.c, apps/lib/apps.c, and apps/{ocsp,s_client,s_server}.c
