BKE_main_id_tag_/BKE_main_id_flag_ were horrible naming now that we split those
into flags (for presistent one) and tags (for runtime ones).
Got rid of previous 'tag_' functions behavior (those who were dedicated shortcuts
to set/clear LIB_TAG_DOIT), so now '_tag_' functions affect tags, and '_flag_'
functions affect flags.
The combined pass is built with the contributions the user finds fit.
It is useful for lightmap baking, as well as non-view dependent effects
baking.
The manual will be updated once we get closer to the 2.77 release.

This is purely internal sanitizing/cleanup, no change in behavior is expected at all.
This change was also needed because we were getting short on ID flags, and
future enhancement of 'user_one' ID behavior requires two new ones.
id->flag remains for persistent data (fakeuser only, so far!), this also allows us
100% backward & forward compatibility.
New id->tag is used for most flags. Though written in .blend files, its content
is cleared at read time.
Note that .blend file version was bumped, so that we can clear runtimeflags from
old .blends, important in case we add new persistent flags in future.
Also, behavior of tags (either status ones, or whether they need to be cleared before/after use)
has been added as comments to their declaration.

Combine all the highpoly pixel arrays into a single array with a lookup
object_id for each of the highpoly objects.
Note: This changes the Bake API, external engines should refer to the
bake_api.c for the latest API.
Many thanks for Sergey Sharybin for the complete review, changes
suggestion and feedback. (you rock!)

I/O

Scene Render Views
* Ability to have an arbitrary number of views in the scene
Missing Bits
============
First rule of Multi-View bug report: If something is not working as it should *when Views is off* this is a severe bug, do mention this in the report.
Second rule is, if something works *when Views is off* but doesn't (or crashes) when *Views is on*, this is a important bug. Do mention this in the report.
Everything else is likely small todos, and may wait until we are sure none of the above is happening.
Apart from that there are those known issues:
* Compositor Image Node poorly working for Multi-View OpenEXR
(this was working prefectly before the 'Use Multi-View' functionality)
* Selecting camera from Multi-View when looking from camera is problematic
* Animation Playback (ctrl+F11) doesn't support stereo formats
* Wrong filepath when trying to play back animated scene
* Viewport Rendering doesn't support Multi-View
* Overscan Rendering
* Fullscreen display modes need to warn the user
* Object copy should be aware of views suffix

Added an utility function which performs vertex split based on the loop
normal so now backing API matches to what's happening in Cycles and BI
in terms of autosplit.

Note: RNA API can't use size_t at the moment. Once it does this patch
can be tweaked a bit to fully benefit from size_t larger dimensions.

If the active image node contributes to the final material shader
(meaning it's either directly or indirectly connected to an Output Node)
the user will receive an alert about circular dependency.
Similar to what we do for Blender internal the baking will still happen,
but the user will receive the alert which should prevent the image
saving to happen if the result was not intentional.

Note: This makes no change to the user, the render engine (Cycles) still
need to update the progress during baking. But this is the Blender side
of this.
Note: the custom UV option is only available when calling the operator
via a script. It's currently not exposed in the UI since it's intended
to be used by scripters
To test it:

Suggestion by Andy Davies (metalliandy) to conform with industry standard (custom cage is something else apparently)
Note: this is the last bake related commit I plan for 2.71/rc (unless
everyone agrees that we could squeeze in D546 - custom UVs, which would
be really nice to add for 2.71 scripters)
Note 2: I'll update the wiki docs shortly
There is a new option to select whether you want to use cage or not.
When not using cage the results will be more similar with Blender
Internal, where the inwards rays (trying to hit the highpoly objects)
don't always come from smooth normals. So if the active object has sharp
edges and an EdgeSplit modifier you get bad corners.
This is useful, however, to bake to planes without the need of adding
extra loops around the edges.
When cage is "on" the user can decide on setting a cage extrusion or to
pick a Custom Cage object. The cage extrusion option works in a
duplicated copy of the active object with EdgeSplit modifiers removed to
inforce smooth normals. The custom cage option takes an object with the
same number of faces as the active object (and the same face ordering).
The custom cage now controls the direction and the origin of the
rays casted to the highpoly objects. The direction is a ray from the
point in the cage mesh to the equivalent point to the base mesh. That
means the face normals are entirely ignored when using a cage object.
For developers:
When using an object cage the ray is calculated from the cage mesh to
the base mesh. It uses the barycentric coordinate from the base mesh UV,
so we expect both meshes to have the same primitive ids (which won't be
the case if the cage gets edited in a destructive way).
That fixes T40023 (giving the expected result when 'use_cage' is false).
Thanks for Andy Davies (metalliandy) for the consulting with normal
baking workflow and extensive testing. His 'stress-test' file will be
added later to our svn tests folder. (The file itself is not public yet
since he still has to add testing notes to it).
Many thanks for the reviewers.

When "Selected to Active" is not on, we bake all the selected objects.
This is the same behaviour we have for Blender Internal.
Dev note: I moved most of the validation tests to outside the bake()
routine so the function can be called in loop.

This should be the final fix for the applyrotation issue. It baffles me
that the fix involves discarding the scale transformations for the
normals but it works so I'm happy with it.
