Http client TLS SNI extension support, api for setting ciphersuites

[avrecko]

Http client fails to handshake when connecting to https server that is doing virtual hosts. So just added SNI TLS extension when handshaking SSL_set_tlsext_host_name. This way the server knows which host to serve. Exception in question:

Also added API support for calling SSL_CTX_set_ciphersuites.
