The \fIbackend\fP struct member is one of the defines in the CURLSSLBACKEND_*
series: CURLSSLBACKEND_NONE (when built without TLS support),
CURLSSLBACKEND_OPENSSL, CURLSSLBACKEND_GNUTLS, CURLSSLBACKEND_NSS,
CURLSSLBACKEND_GSKIT, CURLSSLBACKEND_POLARSSL, CURLSSLBACKEND_CYASSL,
CURLSSLBACKEND_SCHANNEL, CURLSSLBACKEND_DARWINSSL or
CURLSSLBACKEND_AXTLS. (Note that the OpenSSL forks are all reported as just
OpenSSL here.)
The \fIinternals\fP struct member will point to a TLS library specific pointer
