Sergey Sharybin bc411ec06e Cycles: Implement an area preserving parameterization sampling for area lamps ...

Replace old code for area lamps which was more like incorrect with more correct
one using the following paper as a reference:

  Carlos Urena et al.
  An Area-Preserving Parametrization for Spherical Rectangles.
  https://www.solidangle.com/research/egsr2013_spherical_rectangle.pdf

Implementation is straight from the paper, currently the rectangle constants are
calculated for each of the samples. Ideally we need to pre-calculate them.

Some comparison images are available there
