[rdesktop-devel] patch for compile warning and openssl ver <0.9.8, based on v1.8.0 release

[Xiaoqiang C. <fe...@gm...>]

1. On network error, return NULL rather than an empty return statement to
conform with function signature.
2. SSL_OP_NO_COMPRESSION is only available for openssl ver >=0.9.8 so check
it before adding the flag.
