[cp-patches] FYI: DSSI run_multiple_synths patch

[Anthony Green]

DSSI soft-synths may provide run_synth or run_multiple_synths functions.
I was only handling the run_synth case before, so some soft-synths
failed to run (like the hexter DX7 clone).   This patch adds support for
the alternate method.  I'm checking it in.

        * native/jni/midi-dssi/gnu_javax_sound_midi_dssi_DSSISynthesizer.c
        (process): call run_multiple_synths if required.
