    # This is a combination of 3 commits

    # The first commit's message is:
    PhoneWindowManager: Changes for WFD.
    - WFD now sends WIFI_DISPLAY_VIDEO intent to set UI orientation.
    - PhoneWindowManager to listen for WFD intents.
    - Display on WFD should be same as seen on the HDMI, so set the
    orientation to HDMI orientation

    # This is the 2nd commit message:
    framework: update WFD session orientation based on UIBC rotation
    User Input Back Channel (UIBC) support in Wifi Display stack
    allows the sink to send control/commands/preferences to the source
    e.g. touch, keyboard/mouse entry, or orientation/rotation.
    PhoneWindowManager needs to listen for UIBC rotation
    intents and update the preferred rotation when WFD is active.
    Note: HDMI rotation lock overrides WiFi Display UIBC rotation.

    # This is the 3rd commit message:
    PhoneWindowManager: Changes for WiFi Display to comply with Android CDD
    Remove definition of Intent action for ACTION_WIFI_DISPLAY_VIDEO from
    Intent.java and make it local to PhoneWindowManager.
