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.
* Extract part of OSSL_HTTP_REQ_CTX_new() to OSSL_HTTP_REQ_CTX_set_expected().

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
