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

Previous macros suggested that from 3.0, we're only allowed to
deprecate things at a major version.  However, there's no policy
stating this, but there is for removal, saying that to remove
something, it must have been deprecated for 5 years, and that removal
can only happen at a major version.

Meanwhile, the semantic versioning rule is that deprecation should
trigger a MINOR version update, which is reflected in the macro names
as of this change.

For every public header file, the old include guard definition needs
to be added in addition to the new one

include/openssl/file.h:

    #ifndef OPENSSL_FILE_H
    # define OPENSSL_FILE_H
    # pragma once

    # include <openssl/macros.h>
    # if !OPENSSL_API_3
    #  define HEADER_FILE_H
    # endif
    ...

This is going to ensure that applications which use the old include guards
externally, for example like this

    #ifndef HEADER_FILE_H
    # include <openssl/file.h>
    #endif

will not fail to compile.

In addition to the legacy guard, the public header files also receive a
'# pragma once' directive.

Make the include guards consistent by renaming them systematically according
to the naming conventions below

For the public header files (in the 'include/openssl' directory), the guard
names try to match the path specified in the include directives, with
all letters converted to upper case and '/' and '.' replaced by '_'. For the
private header files files, an extra 'OSSL_' is added as prefix.

Add a -rsigopt option to the ocsp command that allows signature parameters to be provided for the signing of OCSP responses. The parameters that may be provided to -rsigopt are the same as may be provided to -sigopt in the ca, req, and x509 commands.

This PR also defines a OCSP_basic_sign_ctx() function, which functions in the same way as OCSP_basic_sign(), except that it accepts a EVP_MD_CTX rather than a key and digest. The OCSP_basic_sign_ctx() function is used to implement the -rsigopt option in the ocsp command.
