Rearchitect video driver:
- Define two video I/F(struct imgsensor_ops_s and struct imgdata_ops_s),
and support them.
- CISIF driver supports new video I/F struct imgdata_ops_s.
- ISX012 driver supports new video I/F struct imgsensor_ops_s.
- Move ISX012 driver to general driver directory.
The video stream driver must be intialized from the board to comply with NuttX
NOTE:
Please remove the initalization from any camera example

Fix the build error by initializing the variables before we perform
th querry for the ext control.

Move global variable declaration out of include/nuttx/video/video.h and into the file where it is initialized. With some toolchains/environments, declaring globals in header files results in multiply defined symobl errors at link time. This corrects that build problem.
* Simplify EINTR/ECANCEL error handling
1. Add semaphore uninterruptible wait function
2 .Replace semaphore wait loop with a single uninterruptible wait
3. Replace all sem_xxx to nxsem_xxx
* Unify the void cast usage
1. Remove void cast for function because many place ignore the returned value witout cast
2. Replace void cast for variable with UNUSED macro
