comment out iterating code

we don't need to iterate over all open spaceclip to find witness cameras
since we now know where the witness comes from (secondary_clip pointer).
However, the con is that we don't know how to access more than one
witness camera. Need to fix this later.

change iterating-all-windows-to-find-witness-clip

- Previously we need to iterate all windows to get witness clips, now we
don't need to do that because it can be accessed by secondary_clip
poitner in SpaceClip. Correspondence links are confined to
'correspondenc' mode.

- Restore 'synchronize two frame bars'

change get clip functions

- change all ED_space_clip_get_clip to ED_space_clip_get_clip_in_region
to enable selection in correspondence mode. Since in this mode we need
to access winess clip (secondary_clip) pointer.

remove duplicate code of drawing secondary clip

- main clip and witness clip seem to only differ in one pointer, use a
function utility to handle different context change, so that other
duplicate code for witness clip can be remove.

remove duplicate code by adding a movieclip select

make the witness clip context shown right

- duplicate code in clip_draw_secondary_clip and clip_draw_main
- selecting in a sub-region is a problem

add region free function

fix region data free error

remove debug info of last commit

fix bug in chaning mode

- error: when 'tracking' mode is clicked, it also enter into 'correspondence' mode.
the if-else logic was wrong

move duplicate code to region_splitview_init

add a flag field to RegionSpaceClip

- this field is to specify main clip or secondary clip, used in drawing
code

Multiview reconstruction: Hack/workaround for the view split

Please follow the comment to see what's going on here.

Ideally i think we need to modify region_rect_recursive() so it does
proper business. Seems that will be safe since i couldn't find any
other usages of VSPLIT and HSPLIT, but want to have interface team
involved here since i might be missing something here.

WIP: drawing secondary clip

Merge branch 'master' into soc-2016-multiview

separating panning fields to RegionSpaceClip

- each sub-region now has its own zoom and panning
- leave stabilization fields in SpaceClip as-is.

recover view when changing from correspondence mode

seperate zoom from SpaceClip to RegionSpaceClip

- mark zoom in SpaceClip as deprecated
- known issue: versioning is not done
