3adc2d90c5 b=986901 don't assume that DelayNode maxDelayTime is greater than 1 block r=padenot 
Also apply DelayNode maxDelayTime before rounding to ticks.

0935b39ced b=857610 handle DelayNode channel count changes and separate buffer read and write r=padenot 
The basic idea is to write out the signal that came in with the same number of
channels as it had when it came in.  Things get a bit more complicated when
one output block may be derived from more than one input block, each having
different numbers of channels.  When this happens, the input blocks with fewer
channels are upmixed, so as not to lose (or distort) any signal in the block
with more channels.

HRTFPanner no longer uses exponential decay (with time constant 20ms) for
delay changes, but a smoother linear transition during cross-fade time (~45ms).

343e110e70 b=923301 keep a tail-time reference on DelayNode until *after* the last non-silent block has been produced r=roc

2900c28a02 b=910174 add DelayNode's tail-time reference as soon as the engine receives sound r=ehsan 
This removes the dependence on AllInputsFinished() which didn't return true
for many input types.

The DelayProcessor is no longer continuously reset (bug 921457) and the
reference is now correctly added again when all inputs are finished and then
new inputs are connected.

ff2971de14 Bug 853298 - Part 1: Switch the ownership model of audio nodes to be based the cycle collector with wrapper caches; r=roc 
Here is what this patch does:
 * Got rid of the JSBindingFinalized stuff
 * Made all nodes wrappercached
 * Started to hold a self reference while the AudioBufferSourceNode is playing back
 * Converted the input references to weak references
 * Got rid of all of the SetProduceOwnOutput and UpdateOutputEnded logic

The nodes are now collected by the cycle collector which calls into
DisconnectFromGraph which drops the references to other nodes and destroys the
media stream.  Note that most of the cycles that are now inherent in the
ownership model are between nodes and their AudioParams (that is, the cycles
not created by content.)
