    camera: Add options to better control video preview size

     * usePreferredPreviewSizeForEffects is needed to fix camcorder effect on
       some MSM8660 devices.
     * Add ignorePreferredPreviewSizeForVideo to use the best size reported
       by the driver instead of the preferred-preview-size-for-video value,
       which may report something really awful.

    Adapted for cm-10.1 from similar commits in jellybean.

    Camera: HDR: don't reset focus manager when HDR is active.

    HDR takes time to compute. So disable any refernce to zsl except
    for actual take it in zsl command.
    due to a recent commit http://review.cyanogenmod.org/#/c/45730/
    I didn't know it was merged in less than 24 hours as HDR commit.

    camera: fix image capture review mode when zsl is enabled

    Choosing "Take Photo" to change a contact image doesn't show
    the captured imaged after taking a snap if ZSL is enabled.
    Also observed on apps that use the native camera to capture
    an image like Whatsapp.

    In ZSL mode, the preview is not stopped, due to which the
    review mode (ImageCapture) doesn't show the captured frame.
    Hence stop the preview if ZSL mode is active so that the
    preview can be restarted using the onReviewRetakeClicked().

    Also, reset the autofocus and set the camera to idle only
    when the ZSL mode is active. This fixes issues with non ZSL
    cameras where autofocus works even during the review mode
    after taking the snap since the camera state is set to idle.

    camera: Add support for ZSL on new Samsung devices

     * The camera driver on new Samsung devices requires that we send a
       magic command to the hardware in order to get ZSL behavior with
       continuous preview. On previous devices, this worked as long as the
       "cam_mode" parameter was zero (instead of null) and "camera-mode" is
       set to 1. On JF, we need to do all of these things.
     * The command we need to send is 1508, but I do not know what this
       value actually corresponds to. It was discovered by reverse
       engineering.
