Forward Port Connect Hangout Demo Patches to Tip

Notes:
[2012/5/31 pfefferz]: Put notes here.
[2012/6/4 Annamalai]:
1) Obtained a UVC compliant MS Web Cam
2) Android Video nodes are updated for camera
3) working with Sangwook on USB and WiFi Stability
[2012/6/5 Annamalai]
4) Implemented a Method of probing video nodes in Android HAL to make sure improper video nodes(/dev/videoX) are not opened to success, eg: JPEG video node in samsung origen board should not be opened for success in camera application, the current implementation is not very good to distinguish between different videoX nodes.
5) Debugging the Stack Corruption problem, step/step to find which camera v4l HAL
is causing cam app to crash
[2012/6/6 Annamalai]:
6) The crash is found due to some string copy in /dev/videoX open calls, have a temporary fix for making it work.
7) The cam gets Initilaized OK, APP opens Success, but the DQBUF is failing, need to see the compatability of the V4L HAL with Driver and further
8) DQBUF failure is due to inadvertant comment out, fixed now.
9) Camera is Fixed Now!
10) Working on releasing the patch set
11) Camera Fix Patch Set released and merged
12) Need to automate DNS setting for WiFi in Android, Work with Sangwook or Botao on this
13) Looks like 1202 Hangout Build works with WiFi properly, so need to compare with 1205 as what can be missing in Android HAL? like DNS setting may be ?
14) Need to test GAPPS Now.
[2012/6/8]
14) Working on Audio IN testing
15) Working with Botao on WiFi and GApps testing
