2nd full patch GstVideoRegionOfInterestMeta and manipulators

Ok, I did my best to address all the comments but please have a good look: I'm
no familiar with the GQuarks, metas and the like :)

- added tags size and orientation to Region of Interest Meta
- add a Region of Interest transform meta function
- Added quark part for a region of interest of type "bounding-box"
- added a method to get the meta indexed by id (but not all of them at once :(
)
- changed gst_buffer_add_video_region_of_interest_meta() into two other
functions, one with a gchar* type and another with a GQuark type.

To make it a bit more generic, the quark is only defined for bounding-box:
"gst-video-region-of-interest-bounding-box"
