Bug 212838: audio/fluidsynth: Add sndio support

fluidsynth.diff

This adds an option SNDIO which enables support for both audio output and MIDI
input over audio/sndio to Fluidsynth.

Unfortunately Fluidsynth does not have upstream support for sndio, so the patch
is relatively large.  If this is a problem I can create a separate port
instead.

This is mostly sourced from the OpenBSD ports tree.  The OpenBSD port uses
autoconf while the FreeBSD port has opted for cmake, so I had to add the sndio
sources to the cmake build files instead.

portlint ok, Poudriere build on FreeBSD 10.3/amd64 ok
