Fix Collada: replaced nullptr by NULL at various places

To remain compatible with the c++ version used in master

Cleanup Collada: Renamed Enum entries for consistency

Minor change: indentation of BC_ANIMATION_TYPE_FROM_NAME was wrong

Cleanup Collada: Removed no longer needed method

Fix Collada: Import of animations for objects with multiple materials

When importing multiple materials for one object,
the imported material animation curves have all been
assigned to the first material in the object.

This fix also improves the console logging whenever the importer
finds a consistency problem with the imported animation data.

Initial fix for CUDA, OpenCL sparse grid sampling.

Fix Collada: Export of sampled animations exports nothing

When exporting animations as matrix data, the exporter did not
create anything. This was because i forgot to copy the sampled
object matrix to the BCSample while decomposing the matrix.
The fix makes sampled animation export work again

Refactor Collada: Renamed files to better match class names:

* Renamed files:
old names: BCAnimationCurveContainer.*
new names: BCAnimationSampler.*

* Adjusted the include files to the new names

Refactor Collada: simplified API

replaced methods from BCAnimationCurveContainer:

BCSample &add(Object *ob, Matrix &mat);
BCSample &add(Object *ob, Bone *bone, Matrix &mat);
BCSample &add(Object *ob, Matrix &mat, int frame_index);
BCSample &add(Object *ob, Bone *bone, Matrix &mat, int frame_index);

by much simpler methods:

BCSample &add(Object *ob);
BCSample &add(Object *ob, int frame_index);

Refactor Collada: BCMatrix is now decomposed on init

Previously the BCMatrix object was decomposed when needed the first time.
But since the decomposition is done always for every single Matrix,
we can do it right upon construction with the additional benefit that
we can handle euler rotations nicer, see

void BCMatrix::set_transform(Object *ob)

There we now can use quat_to_compatible_eul() to avoid axis flipping
during exporting of object transforms. (todo: apply this also for
bone animations)

Fix Collada: added missing private: to CBSample declaration

Refactor: Added useful typedefs to BCSample.h

Cleanup Collada: Change variable name from sample to matrix

this was a leftover from a previous cleanup where i separated
the old BCSample into 2 classes BCSample and BCMatrix

Refactor Collada: reorganized the BC classes for easier use

* Made many changes to make the usage of the BCAnimationSampler
much easier.

* Reorganized the header files
* renamed methods for better reading
* Added Matrix typedef to replace float mat[4][4]
* simplifdied the construction of BCSampleData entries
* Added BCCamera BCLamp and BCMaterial classes
* Added support for Camera xfov export
* Added supprot for easier FCurve modifications
through the BCAnimationCurve API
* Added comments
* Removed unnecessary code
* Simplified code wherever possible

Several minor fixes and variable name changes.

Notable changes:
* P_v moved to correct location in ShaderData struct and shader init.
* Volume motion blur now also checks if the Deformation Blur box in
the Object panel is checked.
* Changed OpenVDB variable names to refer to generic volumes.

cleanup Collada: renamed method, removed not needed method

* renamed get_matrices() to get_samples()
Because the returned list no longer contains a set of matrices

* removed is_flat() test method on BCSamples becasue it actually makes
no sense here.

Cleanup: Collada: Changed comment on BCSample

Cleanup: Collada: Removed no longer needed methods

Refactor: Collada: Moved matrix functions from BCSample to BCMatrix

The affected methods:

rotaiton()
location()
scale()
quad()
decompose()

These methods really did not belong to the BCSample itself. That
was just a left over from previous changes to the BCSample class.
Moved to BCMatrix where they belong to.

Refactor: Collada: Added classes for Lamp and Camera

After i needed to add extra structure for Material and Armature
it is now time to have also Camera and Lamp objects. those objects
are pretty muchg just data at the moment. However this makes the
code more readable without loosing anything.

Refator: Collada: replaced BCSampleKey by Object*

After doing some simplifications BCSampleKey has
degraded to alwasy be ob->id.name So i replaced the key
by the object pointer itself.
