Support FreeRDP 1.1.0

There are two build issues with FreeRDP support in VLC:

1. It fails to build with current FreeRDP API changes. See http://trac.macports.org/ticket/42664 and http://www.freebsd.org/cgi/query-pr.cgi?pr=185848 ... there are src changes referenced in those tickets, but they are not backwards compatible.

2. Once that is addressed (see patches referenced in either of those two downstream tickets), VLC fails to link due to missing symbols. A quick glance at them revealed that libssl and libcrypto were missing, and that is solved by:
