Methods are named more consistently and have a more consistent
signatures. The call structure of mixing is slightly
simplified. Anonymous participants are also ramped up.

Changes to the mixer unittests:
Removed the tests related to the former 'OutputMixer', as it's going
to be removed. Removed incorrect comparison tests with the old mixer
because doing identical mixing decisions with the old mixer proved
unviable.
When the new mixer went from kMaximumAmountOfMixedAudioSources in the
last iteration to kMaximumAmountOfMixedAudioSources+1, it could hit an
RTC_NOTREACHED(); Added fix to mixer and test
AudioMixer.RampedOutSourcesShouldNotBeMarkedMixed that covers that
case.

Added a level indicator to the new mixer. The level indicator is
webrtc::voe::AudioLevel. It computes the current audio level, which is
used all the way up to peerconnection.
This is part of the project to rewrite the old conference mixer and
output mixer.

The folder structure is now as was agreed on in the 'Slim and Modular
WebRTC' effort. Also added some dependencies that were previously in
another part of the tree.

Removed resampler from NewAudioConferenceMixer and AudioMixer (which started as a copy of former OutputMixer). This is part of the mixer rewrite project. In particular,
this is one of the steps required to have a single mixing component
instead of two doing the same thing.
The next planned change (which is not part of this CL) is to plug in the
new mixer (NewAudioConferenceMixer) into AudioState and AudioDeviceModule.

The new version is much shorter than the old one, and hopefully easier
to read. This is part of the effort to rewrite the old mixer.

Reason for revert:
Multiple definitions of webrtc::MockMixerParticipant::MockMixerParticipant() during linking of modules_unittests. Please investigate and resubmit.

Memory frames are now expected to be owned by the mixing participants.

OutputMixer and AudioConferenceMixer communicated via a callback. OutputMixer implemented an AudioMixerOutputReceiver interface, which defines the callback function NewMixedAudio. This has been removed and replaced by a simple function in the new mixer. The audio frame with mixed audio is now copied one time less. I have also removed one forward declaration.
