Added SQPnP algorithm to SolvePnP
* Added sqpnp
* Fixed test case
* Added fix for duplicate point checking and inverse func reuse
* Changes for 3x speedup
Changed norm method (significant speed increase), changed nearest rotation computation to FOAM
* Added symmetric 3x3 inverse and unrolled loops
* Fixed error with SVD
* Fixed error from with indices
Indices were initialized negative. When nullspace is large, points coplanar, and rotation near 0, indices not changed.
* 'master' of github.com:itseez/opencv: (82 commits)

Updated the documents to give warning to the users of `findHomography` that the function may return an empty matrix in some cases.
The user must take care of checking that.
The `calib3d.hpp` has a definition of the constant that does not contain the prefix "CV_".
The affected methods were `findHomography` and `findEssentialMat`.
Now the documentation updates the definition of the constants to conform to the header.
Fixed inconsistency with flag names for solvePnP.
The default value for the function lacks the CV_ prefix. The code checks against "ITERATIVE". The suggested values for the parameters *include* the prefix.
Even though the enum CV_ITERATIVE (+ CV_P3P, CV_EPNP) = ITERATIVE (& P3P, EPNP), lets show to the users only one of them.
Now the user sees only {ITERATIVE, P3P, EPNP}.
