Video Encoder: Enable Ducati h264 encoder profile change

This patch enables the TI ducati H264 encoder profile
via BoardConfig setting:
BOARD_USE_TI_DUCATI_H264_PROFILE := true

Allows correct video decoding on Motorola OMAP4 / Kindle Fires
and other devices using newer DOMX libs.

Effectively a cherry-pick of omapzoom commit (with creative
board setting name):

[3/3] av: Allow custom DOMX source instead of Google DOMX default

Part 3 of 3 patches: To allow omap4 devices to use custom "domx" source
via a new BoardConfig.mk item:
TI_CUSTOM_DOMX_PATH := device/<manufacturer>/<device-name>/domx

This setting provides for 3 changes during the build:
1. In hardware/ti/omap4xxx this settings stops standard Google domx
source from being built and changes the domx reference for tiutils.
2. In frameworks/base it changes the default openmax references for
frameworks/base/media/jni/mediaeditor/Android.mk to the new location
3. In frameworks/av changes the openmax references in 5 places, and adds
new includes in ACodec.cpp, CameraSource.cpp and OMXCodec.cpp

This commit is based on cherry-pick from omapzoom (with a more descriptive
BoardConfig setting name):
