From 022818b4a796f52c0a91eea42e65aec0bc7bed43 Mon Sep 17 00:00:00 2001
From: David Robillard <d@drobilla.net>
Date: Tue, 17 Feb 2009 02:11:49 +0000
Subject: Fix the horrible mess that was anything related to sources and paths.

Most significant changes:

 - Factor out FileSource from AudioFileSource, use for SMFSource too
 - Explicitly pass embedded rather than mysterious name mangling or whatever
 - Destroy a ton of duplicated or very-nearly-duplicated code
 - Clean up and document all that weird source stuff in session.cc
