First thing changed by this commit is making it so
Euclidean intersection takes track weight into account
when solving minimization problem. This behaves the
same exact way as it is for BA step.
Second thing is related on how average reprojection error
is being calculated. It didn't take track weight into
account which could confuse users. Now average reprojection
error will give the same result as intersection/BA uses
during minimization which gives much more predictable
behavior.

Using tracks with constant zero weight used to crash
keyframe selection since it was trying to use missing
parameter blocks for Jacobian evaluation,
Also fixed possible issues with wrong camera block being
marked as variable. This could technically happen when
having zero weighted tracks. Made it so all camera blocks
are marked as variable for now.
Switch the detector API to a single function which accepts
a float image and detector options. This makes usage of
feature detection more unified across different algorithms.
Options structure is pretty much straightforward and contains
detector to be used and all the detector-specific settings.
Also implemented Harris feature detection algorithm which
is not as fast as FAST one but is expected to detect more
robust feature points. It is also likely that less features
are detected, but better quality than quantity.
Blender will now use Harris detector by default, later we'll
remove FAST detector.
r_frame_rate is a guessed number defined as "the least common multiple of
all framerates in the stream". It has been deprecated and removed in new
Libav releases.
Use avg_frame_rate instead, which is the average framerate of the
stream.
CODEC_ID_* have been replaced with AV_CODEC_ID_* in new libavcodec
versions.
Update the code to use those new identifiers.
Added a compatibility code to ffmpeg_compat.h
Fixes some issues with NaN vertices in special cases.
Also adds edge interpolation routines which are currently
unused but which are requires to implement edge CD interpolation.
So now it's possible to copy-paste splines between layers.
Implementation is pretty much straightforward and duplicates
some logic which we've got in sequencer/tracking clipboards.
Will work on a common routine for clipboards later, for now
it's not so much crucial to have.
Updated CMakeLists.txt to account for boost hardcoded locations for VS 2013.

Changed curve active point from pointer to index. Allows curve active point to be saved to file and retained between modes for free. Also some small optimisations by removing pointer look up code.
- Made active point access functions into BKE API calls.
- Fixes operators where curve de-selection resulted in unsel-active point.
- Split curve delete into 2 functions
* Very simple implementation, only allows for 1 output socket. As we haven't decided yet whether we keep the XML API, rather not spend more time on this now.
* To use an external osl shader, put the .osl file next to the xml file.
* Parameters: "output" is the output socket name, "output_type" the variable type (float, color and closure color are supported).
Example:
<osl_shader name="tex" src="ramp_closure.osl" output="Phong" output_type="closure color" />
<connect from="tex Phong" to="output surface" />
Factorized a bit the code here, think it's more readable now... No performance enhancement though.
