From 177f2b48b6516ba4dee70a709ce28105f1092de2 Mon Sep 17 00:00:00 2001
From: David Robillard <d@drobilla.net>
Date: Wed, 18 May 2011 17:45:39 +0000
Subject: Use an intrusive linked list for event queue rather than Raul::List.

This avoids the need to allocate list nodes, improving performance (event throughput), and making EventSource::push_queued realtime safe.

Remove unused queue_size parameter from EventSource and friends.
