The V4L capture provider was quite buggy and did not work on OpenSolaris. [[OpenSolaris]]. I've tried to fix the most obvious problems I could see:
* Made V4L1 optional
* Fixed V4L2 cvInitImageHeader w/h parameters
* Fixed V4L2 mmap buffer use to remove memcpy workaround
* Fixed V4L2 buffer selection when converting
* Added support for OpenSolaris [[OpenSolaris]] V4L2
* Added support for reading without polling
* Added support for V4L2_CAP_READWRITE
