net/freerdp: Update to 2.0.0 pre-release (GitHub as of 2016.11.24)

• This update brings in the latest 2 years of FreeRDP project work, which has had a long time between tagging releases.
• Remove DIRECTFB option, as it no longer compiles, and gets little upstream maintenance
• Use NEON on aarch64, and optionally on armv6
• Mark as broken on armv6 on FreeBSD 11.0-RELEASE and early versions of 12.0-CURRENT
• Fix issue with X11_USE=xorg= being truncated due to whitespace as it wrapped over multiple lines
• Move installed *.cmake files to correct location for modules

net/freerdp1:

• create new port based on previous net/freerdp 1.2.0, as it is required by net/guacamole-server

net/vinagre:

• patch to work with the new version of net/freerdp 2.0.0

net/guacamole-server:

• patch to work with net/freerdp1
