SoftFloat integrated ( #8668 )
...
* everything is put into softfloat.cpp and softfloat.hpp
* WIP: try to integrate softfloat into OpenCV
* extra functions removed
* softfloat made stateless
* CV_EXPORTS added
* operators fixed
* exp added, log: WIP

* minors, refactoring
* "inline" -> "CV_INLINE"
* cast to bool warnings fixed
* several warnings fixed
* fixed warning about unsigned unary minus
* fixed warnings on type cast
* inline -> CV_INLINE
* special cases processing added (NaNs, Infs, etc.)
* constants for NaN and Inf added
* more macros and helper functions added
* added (or fixed) tests for pow32, pow64, cbrt32
* exp-like functions fixed
* minor changes
* fixed random number generation for tests
* tests for exp32 and exp64: values are compared to SoftFloat-based naive implementation

* CV_INLINE -> inline
* internal constants moved to .cpp file
* toInt_minMag() methods merged into toInt() methods
* macros moved to .cpp file
* refactoring: types renamed to softfloat and softdouble; explicit constructors, etc.

fix solveCubic
...
The original solution did not handle correctly when delta = 0,
resulting as nan errors. I also wrote a test case to test solving
equation x^3 = 0 after fixing.

Several type of formal refactoring:
...
1. someMatrix.data -> someMatrix.prt()
2. someMatrix.data + someMatrix.step * lineIndex -> someMatrix.ptr( lineIndex )
3. (SomeType*) someMatrix.data -> someMatrix.ptr<SomeType>()
4. someMatrix.data -> !someMatrix.empty() ( or !someMatrix.data -> someMatrix.empty() ) in logical expressions

Fixed several problems found by PVS-Studio.
...
This fixes all problems from the article "Checking OpenCV with PVS-Studio"
<http://www.viva64.com/en/b/0191/ > that are not already fixed and are
not in 3rdparty or the legacy module.
The problems fixed are two instances of useless code and one instance
of unspecified behavior (right-shifting a negative number).

Add implementations for Mat::zeros() and Mat::ones()
...
In class Mat, "static MatExpr Mat::zeros(int ndims, const int* sz, int
type)" and "static MatExpr Mat::ones(int ndims, const int* sz, int
type)" are declared but never implemented. That means we can see their
manuals from
"http://docs.opencv.org/modules/core/doc/basic_structures.html " but we
can't use them. Here I tried to finish their implementation.
I have also changed MatOp_Initializer::assign to make it support
multi-dimension Mat.
Test cases are added in test_math.cpp as well.
