2a06c2a03e mpegvideo_enc: Draw edges on input for non-multiple of 16 resolutions
This improves motion estimation and avoids using uninitialized data
for resolutions that aren't a multiple of 16.

Prior to d2a25c40, the edges used to be initialized so that encoding
was deterministic, but after that commit it started using uninitialized
data (for non multiple of 16 resolutions).

e2ad0b66fa imgutils: create misc functions for dealing with buffers
Move the lavc/imgconvert functions and rename them as follows:
  avpicture_get_size -> av_image_get_buffer_size()
  avpicture_fill     -> av_image_fill_arrays()
  avpicture_layout   -> av_image_copy_to_buffer()

The new functions have an align parameter, which allows to define the
linesize alignment assumed in the buffer (which is set or read).

The names of the functions are consistent with the lavu/samples API
(av_samples_get_buffer_size(), av_samples_fill_arrays()).

A redundant check has been dropped from av_image_fill_arrays().

8a3d9ca603 libavcodec: Add an OpenH264 encoder wrapper
Compared to existing, common opensource H264 encoders, this can be
useful since it has got a different license (BSD instead of GPL).

Performance- and qualitywise it is comparable to x264 in ultrafast
mode.

Hooking it up as an encoder in libavcodec also simplifies comparing
it against other common encoders.

This requires OpenH264 1.3 or newer. Since the OpenH264 API and ABI
changes frequently, only releases are supported.

To take advantage of the OpenH264 patent offer, the OpenH264 library
must not be redistributed, but downloaded at runtime at the end-user's
system.

c220a60f92 vdpau: add helper for surface chroma type and size
Since the VDPAU pixel format does not distinguish between different
VDPAU video surface chroma types, we need another way to pass this
data to the application.

Originally VDPAU in libavcodec only supported decoding to 8-bits YUV
with 4:2:0 chroma sampling. Correspondingly, applications assumed that
libavcodec expected VDP_CHROMA_TYPE_420 video surfaces for output.
However some of the new HEVC profiles proposed for addition to VDPAU
would require different depth and/or sampling:
http://lists.freedesktop.org/archives/vdpau/2014-July/000167.html
...as would lossless AVC profiles:
http://lists.freedesktop.org/archives/vdpau/2014-November/000241.html

To preserve backward binary compatibility with existing applications,
a new av_vdpau_bind_context() flag is introduced in a further change.

e0bb74a140 exr: Add a gamma flag to exr loader to avoid banding
This is needed to avoid banding artifacts when gammaing the picture.
Currently, if done with a video filter, the process is done on uints
instead of full float.

to still initialize it though.
