gst1-imx: add package

From: Gary Bisson <[email protected]>

Open-source GStreamer 1.0 plugins for i.MX6 platforms. More info at https://github.com/Freescale/gstreamer-imx

---
Modifications v3->v4:
- Bump version to 0.10.1

Modifications v2->v3:
- Change package name from gst1-plugins-imx to gst1-imx
- Remove commands unnecessary parentheses
- Modify package comment to clarify it is only working on i.MX6

Modifications v1->v2:
- Use of github helper macro
- Modify package comment with Peter S. original patch
- Add comment for eglibc dependency (due to GPU libs)
- Remove comments on package dependencies

This patch has been tested using an i.MX6Q SabreLite (nitrogen6x config) along with the usual Tears of Steel movie in 1080p:
http://media.xiph.org/mango/tears_of_steel_1080p.webm

Below are the commands used to test the different sinks:

$ gst-launch-1.0 playbin uri=file:///root/tears_of_steel_1080p.webm
$ gst-launch-1.0 filesrc location=/root/tears_of_steel_1080p.webm ! \
matroskademux ! imxvpudec ! imxipusink
$ gst-launch-1.0 filesrc location=/root/tears_of_steel_1080p.webm ! \
matroskademux ! imxvpudec ! imxeglvivsink

The toolchain used was the Sourcery CodeBench 2014.05. The video above also requires the following extra configuration in order to demux the content:
BR2_PACKAGE_GST1_PLUGINS_GOOD=y BR2_PACKAGE_GST1_PLUGINS_GOOD_PLUGIN_MATROSKA=y

Thanks,
Gary

+	  This is a set of GStreamer 1.0 plugins for plugins for Freescale's
+	  i.MX6 platforms, with emphasis on video en/decoding using the VPU
+	  engine.
+
+	  This software supports only the i.MX6 SoC family and requires a
+	  kernel that includes the i.MX6 specific headers to be built.
+
+	  The software as a whole is currently in beta stage.

2.1.4

My test scenario:
gst-launch-1.0 -e v4l2src device=/dev/video0 ! \
video/x-raw,width=640,height=480,framerate=15/1 ! \
imxipuvideotransform ! \
imxvpuenc_h264 idr-interval=16 bitrate=512 ! \
rtph264pay config-interval=5 pt=96 ! \
udpsink host=10.203.100.24 port=11111 sync=false

CPU usage -- cca 15 % on single core (imx6).
