Because with libimxvpuapi older than 0.10.3, the gst1-imx-0.12.3 "imxvpu"
plugin will not build.
Changelog:
* properly pass on color format in simplified JPEG encoder interface
* add alternative write-callback-style encoding mode
also add encode example variant which uses write-callback style output
* add support for "fake grayscale mode" in encoders
this is done by using I420 internally and filling the U and V planes
with 0x80 bytes
* make sure JPEG quantization table is copied in standardized zig zag order
the VPU does not, so this has to be done explicitely

Changelog:
- fix AUD NAL positioning in h.264 encoder output
(SPS/PPS/AUD were ordered incorrectly - AUD has to come first, not last)
- fix build error with examples when --enable-static is used
- pass quality factor in simplified JPEG encoder interface correctly
- add functions for querying and setting header data
useful for modifying headers, like VUI data in the SPS RBSP
- documentation updates
This patch is based on the Yocto equivalent:
https://github.com/Freescale/meta-fsl-arm/commit/c999668
Implicitly tested through gstreamer as the plugin relies on it:
# gst-launch-1.0 playbin uri=file:///root/tears_of_steel_1080p.webm

This is a library for using the i.MX6 VPU. It is an alternative to
libfslvpuwrap, hosted on Github, and has an API that features several
improvements over libfslvpuwrap, which include:
* User-defined context information associated with input frames, which
is passed on to corresponding output frames (to be able to identify
which input frame produced which output frame)
* Groundwork for future DMA-BUF/BMM/ION/CMA allocator integration, using
file descriptors instead of physical addresses
* Indicators for when it is safe to try to decode frames, which is
critical in multi-threaded playback cases
* Simplified, higher-level JPEG en/decoding API, based on the VPU MJPEG
codec; useful for picture viewing without the extra boilerplate for
VPU-based en/decoding
Changelog 0.10.0 -> 0.10.1:
- add debian packaging files
- update waf to version 1.8.16
- add workaround in wscript to prevent stale pkg-config .pc files
- fix memory leak by adding missing IOFreeVirtMem() call in vpulib
backend
