getUserMeida: report device starting states

Chromium used to report device started immediately at requesting user media,
despite the device operation results. This causes several kinds of problems.
 - Notification of capture starting is shown before device starts.
 - gUM gets successful callback even if the device fails to start.
So we decide to make gUM return the real device starting states
(here we focus on the video capturing).
This is the first part of the complete modification.
The design doc is here, https://goo.gl/WTZkEl
The complete CL is here, https://codereview.chromium.org/2658643002

This CL implements the device-started-state reporting part. Each device will
report OnStarted event all the way back to VideoCaptureImpl when it's started
successfully(Error report has been done already).
This CL also includes all the necessary modifications due to the interface
change.
This CL will take no effect to getUserMedia behavior at present until another
CL which will handle the OnStarted event is landed.

getUserMedia: handle the device starting status report.

Chromium used to report device started immediately at requesting user media,
despite the device operation results. This causes several kinds of problems.
 - Notification of capture starting is shown before device starts.
 - gUM gets successful callback even if the device fails to start.

This is the second part of the complete modification.
The design doc is here, https://goo.gl/WTZkEl
The previous CL is here, https://codereview.chromium.org/2673373003/

This CL does severals things when a OnStarted event from device arrives
- VideoCaptureImpl calls the state_update_cb, informing the track is completed.
- When all tracks are completed, return gUM with successful callback and send
  a message to browser process to show the notification in UI.
- Other related changes due to the asynchronous OnStarted event.
- Remove some test cases of desktop_capture, which tests nothing before
(due to the always-successful gUM callback) and fails after this cl
(gUM will get errorcallback if stream can't be started successfully).
