398f7059fc webrtcdsp: Add WebRTC Audio Processing support
This DSP library can be used to enhance voice signal for real time
communication call. In implements multiple filters like noise reduction,
high pass filter, echo cancellation, automatic gain control, etc.

The webrtcdsp element can be used along, or with the help of the
webrtcechoprobe if echo cancellation is enabled. The echo probe should
be placed as close as possible to the audio sink, while the DSP is
generally place close to the audio capture. For local testing, one can
use an echo loop pipeline like the following:

  autoaudiosrc ! webrtcdsp ! webrtcechoprobe ! autoaudiosink

This pipeline should produce a single echo rather then repeated echo.
Those elements works if they are placed in the same top level pipeline.

e28b123608 dc1394src: port to 1.X
The dc1394src is a PushSrc element for IIDC cameras based on libdc1394.
The implementation from the 0.x series is deffective:
caps negotiation does not work, and some video formats
provided by the camera are not supported.

Refactor the code to port it to 1.X and enhance the support
for the full set of video options of IIDC cameras:

  - The IIDC specification includes a set of camera video modes
    (video format, frame size, and frame rates).
    They do not map perfectly to Gstreamer formats, but those that
    do not match are very rare (if used at all by any camera).
    In addition, although the specification includes a raw format,
    some cameras use mono video formats to capture in Bayer format.
    Map corresponding video modes to Gstreamer formats in capabilities,
    allowing both gray raw and Bayer video formats for mono video modes.

  - The specification includes scalable video modes (Format7),
    where the frame size and rate can be set to arbitrary values
    (within the limits of the camera and the bus transport).
    Allow the use of such mode, using the frame size and rate
    from the negotiatied caps, and set the camera frame rate
    adjusting the packet size as in:
    <http://damien.douxchamps.net/ieee1394/libdc1394/faq/#How_do_I_set_the_frame_rate>

    The scalable modes also allow for a custom ROI offset.
    Support for it can be easily added later using properties.

  - Camera operation using libdc1394 is as follows:

      1. Enumerate cameras on the system and open the camera
         identified the enumeration index or by a GUID (64bit hex code).

      2. Query the video formats supported by the camera.

      3. Configure the camera for the desired video format.

      4. Setup the capture resources for the configured video format
         and start the camera transmission.

      5. Capture frames from the camera and release them when not used.

      6. Stop the camera transmission and clear the capture resources.

      7. Close the camera freeing its resources.

    Do steps 2 and 3 when getting and setting the caps respectively.
    Ideally 4 and 6 would be done when going from PAUSED to PLAYING
    and viceversa, but since caps might not be set yet, the video mode
    is not properly configured leaving the camera in a broken state.
    Hence, setup capture and start transmission in the set caps method,
    and consequently clear the capture and stop the transmission
    when going from PAUSED to READY (instead of PLAYING to PAUSED).
    Symmetrycally, open the camera when going from READY to PAUSED,
    allowing to probe the camera caps in the negotiation stage.
    Implement that using the `start` and `stop` methods of `GstBaseSrc`,
    instead of the `change-state` method of `GstElement`.
    Stop the camera before setting new caps and restarting it again
    to handle caps reconfiguration while in PLAYING (it has no effect
    if the camera is not started).

  - Create buffers copying the bytes of the captured frames.
    Alternatively, the buffers could just wrap the bytes of the frames,
    releasing the frame in the buffer's destroy notify function,
    if all buffers were destroyed before going from PLAYING to PAUSED.

  - No timestamp nor offset is set when creating buffers.
    Timestamping is delegated to the parent class BaseSrc,
    setting `gst_base_src_set_live` TRUE, `gst_base_src_set_format`
    with GST_FORMAT_TIME and `gst_base_src_set_do_timestamp`.
    Captured frames have a timestamp field with the system time
    at the completion of the transmission of the frame,
    but it is not sure that this comes from a monotonic clock,
    and it seems to be left NULL in Windows.

  - Use GUID and unit properties to select the camera to operate on.
    The camera number used in version 0.X does not uniquely identify
    the device (it depends on the set of cameras currently detected).
    Since the GUID is 64bit identifier (same as MAC address),
    handle it with a string property with its hexadecimal representation.
    For practicality, operate on the first camera available if the GUID
    is null (default) and match any camera unit number if unit is -1.
    Alternatively, the GUID could be handed with an unsigned 64 bit
    integer type property, using `0xffffffffffffffff` as default value
    to select the first camera available (it is not a valid GUID value).

  - Keep name `GstDc1394` and prefix `gst_dc1394` as in version 0.X,
    although `GstDC1394Src` and `gst_dc1394_src` are more descriptive.

  - Adjust build files to reenable the compilation of the plugin.

    Remove dc1394 from the list of unported plugins in configure.ac.

    Add the missing flags and libraries to Makefile.
    Use `$()` for variable substitution, as many plugins do,
    although other plugins use `@@` instead.

1536f30cc2 openjpeg: Port to 2.1 and require a pkg-config file for 2.0 and 2.1
The port was trivial, and according to the NEWS file nothing else has changed,
but it is possible that other API was changed without proper notification.

OpenJPEG upstream has shipped a pkg-config file for the past 4 years, and all
distros should be shipping it by now.

b5a4de197a configure: improve check for wayland-scanner binary
The plugin doesn't need the wayland-scanner package to be built
or run, it only needs the wayland-scanner program during compile time.

When cross-compiling, build systems might not have the wayland-scanner
package for the target system as it is a developer's tool, while it should
still be possible to use wayland-scanner from the host system.

This patch fixes it by not requiring the wayland-scanner package but
just the binary itself.

Note that the check is done outside of the PKG_CHECK_MODULES
as it doesn't work inside of it.

GCC automatically disable redundance warnings for system headers. As
soon as we start using a non-system installed mesa, we would start
having issues. The test for both wasn't setting any flags, so it would
work but then fail at runtime.

This is being fixed by disabling in the code (where needed only) that
GCC warning. The test is also fixed to avoid the false positive we had.
