Allow MessageFilters to restrict listening to specific message classes
ChannelProxy currently offers messages to all member MessageFilters. It turns
out that a good portion of the most common message types will never be filtered,
making the O(N) filter walk an unnecessary affair. To prevent this, allow
MessageFilters to indicate which (if any) subset of message classes they may
filter, allowing the ChannelProxy to refine the list of filters that are offered
a particular message. This saves ~35us per message received on the browser IO
thread for a typical Android device.
Relanding with a few more guards for MessageFilter removal, access and message
class subscription.
