    /* This is all client transport properties that are implemented as
       simple Curl session properties (i.e. the transport basically just
       passes them through to Curl without looking at them).

       People occasionally want to replace all this with something where
       the Xmlrpc-c user simply does the curl_easy_setopt() call and this
       code need not know about all these options.  Unfortunately, that's
       a significant modularity violation.  Either the Xmlrpc-c user
       controls the Curl object or he doesn't.  If he does, then he
       shouldn't use libxmlrpc_client -- he should just copy some of this
       code into his own program.  If he doesn't, then he should never see
       the Curl library.

       Speaking of modularity: the only reason this is a separate struct
       is to make the code easier to manage.  Ideally, the fact that these
       particular properties of the transport are implemented by simple
       Curl session setup would be known only at the lowest level code
       that does that setup.
