David G Yu ff34c514f5 Improved patch basis eval for Osd to match Far
This updates the patch basis evaluation functions in Osd
to match recent changes to far/patchBasis.

This also exposes a common facility for dealing with PatchCoord,
PatchArray, and PatchParam. These are exposed as global functions
operating on struct data, since C++ style class methods are not
supported by all of the Osd shader and kernel execution envirionments.

Changes:
    - Merged far/patchBasis.cpp to osd/patchBasisCommon{,Types,Eval}.h
    - Exposed PatchCoord, PatchArray, and PatchParam to Osd kernels
    - exposed OsdEvaluatePatchBasis and OsdEvaluatePatchBasisNormalized
    - Updated CPU, TBB, Omp, CUDA, OpenCL, GLSL, HLSL, and Metal evaluators
    - Updated glFVarViewer
