These functions load "serverinfo" TLS ServerHello Extensions into the
SSL_CTX. A "serverinfo" extension is returned in response to an empty
SSL_CTX_use_serverinfo() loads one or more serverinfo extensions from a
byte array into ctx. The extensions must be concatenated into a
sequence of bytes. Each extension must consist of a 2-byte Extension
Type, a 2-byte length, and then length bytes of extension_data.
SSL_CTX_use_serverinfo_file() loads one or more serverinfo extensions
from file into ctx. The extensions must be in PEM format. Each
extension must consist of a 2-byte Extension Type, a 2-byte length, and
then length bytes of extension_data. Each PEM extension name must
begin with the phrase "BEGIN SERVERINFO FOR ".
If more than one certificate (RSA/DSA) is installed using
SSL_CTX_use_certificate(), the serverinfo extension will be loaded into
the last certificate installed. If e.g. the last item was a RSA
certificate, the loaded serverinfo extension data will be loaded for
that certificate. To use the serverinfo extension for multiple
certificates, SSL_CTX_use_serverinfo() needs to be called multiple
times, once after each time a certificate is loaded.
On success, the functions return 1. On failure, the functions return
0. Check out the error stack to find out the reason.
