Subject: [PATCH] Initial commit.

The initial state of the repo is this:
core.c has functions to initialize a synth, control the synth
state, schedule changes to the state, and generate stereo sound
to be used by whatever.

jackclient.c sets a synth as a jack client.

instruments.h has the configuration for the non sampled instruments.
