Current DirectX capturer cannot capture multiple video cards or monitors. But
according to DXGI desktop duplication sample (https://goo.gl/An0L9l), we can
capture multiple video cards and monitors by duplicating them one by one. So
instead of one IDXGIOutputDuplication instance, this change creates an
IDXGIOutputDuplication instance for each monitor, and merge the output into
one DesktopFrame.
Several other changes are also included,
1. Add supports to DXGI_OUTDUPL_DESC.DesktopImageInSystemMemory. When this flag
is true, we won't copy its content to staging buffer.
2. Capture one monitor instead of entire screen.
Above changes make the logic complex. But with some refactor work, the logic is
not disordered. Please refer to the doc @ https://goo.gl/hU1ifG.

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.

After offline discussion, this was mostly of historical use and may
actually be more of a risk now that we have the paced sender.

Scaling causes us to work the CPU too much, which very quickly degrades quality. This causes us to at least behave better on good networks.

Additional changes I needed to make it work:
- Modified a header in RTPFile.cc. Every other file is
using "webrtc/engine_configurations.h" instead.
- Disabled flag 4373 for msvs because it was disabled
in build/common.gypi.

- Removes unnecessary casts to compute timedelta.
- Renames ProbingState for clarity. This should help when we probe mid-call.
- Enables probing by default to avoid checking on each incoming packet.
- Removes duplicate probing state tracking in paced sender. These duplicate
states were conflicting at times.
- Removes passing through packets for bug 5307 which seems long fixed.
- Cleanup handling of time_last_send_ms and avoid side effects of changing
probing state at TimeUntilNextProbe().
- Clear cluster data when probing is restarted to avoid having old data after a reset.

The intended behavior of the pacer is that it should send audio (i.e high priority) packets immediatelly even if the pacer is paused and even if the available media budget has been used. The existing code will not send audio if the pacing budget has been used. It will normally send audio when the pacer is paused, but if the media budget was already used up when the pacer was paused, it would neither send audio nor update the budget.
Updated the implementatation and the unit test. Added logging for when the pacer is paused, and when it receives a zero bitrate estimate.
