Fixes potential use of uninitialized data.

Hi Frank,
Thank you for the v2.
Could we remove all asserts?
Asserts can cause the application to crash at runtime.

Added an OpenCL lut3d video filter implementation for the current lut3d video
filter.
- This OpenCL implementation currently supports only .cube LUT format and 3
interpolations - nearest,trilinear,tetrahedral (default).
- Outputs match CPU version up to floating point errors.

Jan Stud
Patch attached.

These patches remove the ogg header packets from secondary chainged ogg
streams from the demuxer.
First, a test utility is added to track what is currently happening with
chained streams.
Then the changes are introduced: the packet demuxing function is used to
explicitely tell the demuxer to skip

Perform multiple improvements to increase code robustness.
In particular:
- favor unsigned counters for loops
- add missing checks
- avoid possible leaks
- move variable declarations to inner scopes when feasible
- provide explicit type-casting when needed

Instead of initializing a new BPrint in each iteration of
