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).

HTTP client API: Generalize to arbitrary request and response contents

Reviewed-by: Tomas Mraz <tomas@openssl.org>
(Merged from https://github.com/openssl/openssl/pull/15053)

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.

HTTP client: Minimal changes that include the improved API

This is a minimal version of pull request #15053 including all the
proposed improvements to the HTTP client API and its documentation
but only those code adaptations strictly needed for it.

The proposed new features include
* support for persistent connections (keep-alive),
* generalization to arbitrary request and response types, and
* support for streaming BIOs for request and response data.

The related API changes include:
* 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.
