Hello Everyone,

This is the fourth version of extended crop/compose RFC.  The patch-set
introduces new ioctls to V4L2 APIi for configuration of selection rectangles
like crop and compose areas. Please refer to discussion below for more details
about api development.

http://thread.gmane.org/gmane.linux.drivers.video-input-infrastructure/32152

Changelog:

v3:
- added target for padded buffer
- reduced number of constraint flags to SIZE_LE and SIZE_GE
- removed try flag
- added documentation for selection ioctls
- added documentation for new model of cropping, composing and scaling
- support of selection api for s5p-tv
- fixed returning ioctl's structures on failure

v2:
- reduced number of hints and its semantics to be more practical and less
  restrictive
- combined EXTCROP and COMPOSE ioctls into VIDIOC_{S/G}_SELECTION
- introduced crop and compose targets
- introduced try flag that prevents passing configuration to a hardware
- added usage examples
