Introduce some POD structs for describing an external server application and the desired libraries to load from it, and disambiguating between empty list request and invalid list request. This allows for overriding PiperVampPluginFactory behaviour for using a PluginScan to populate the list request.

#!/bin/sh
#
# A very simple command shell for Sonic Visualiser.
# 
# This provides a wrapper for the sv-osc-send program, which is a
# generic OSC sending program (not specific to SV, despite its name).
# This script attempts to guess the OSC port number for an SV
# process running on the local host, and then composes a method name
# and arguments into a complete OSC call.
# 
# You can either run this with the method and its arguments on the
# command line, e.g. "sv-command set layer Frequency-Scale Log", or
# you can provide a series of method + argument commands on stdin.
# 
# Unless you use the -q option, this script will echo the OSC URL
# and arguments that it is sending for each command.
#
# Note that the method and arguments may not contain spaces.
#
