bf8b7e08f1 0030492: Foundation Classes - math_BFGS fails if starting point is exactly the minimum
Fix affects BFGS optimization methods by checking convergence as the first step on each iteration. FRPR works well, but it is updated as well since its logic potentially dangerous.

f79b19a17e 0028175: Bad result of curve-curve extrema
Extrema between curves has been made producing correct result for the cases of solution located near bounds.

- Class math_GlobOptMin has been improved to use lower order methods of local optimization when high-order methods are failed.
- Add support of conditional optimization (in bounds) in the classes math_BFGS and math_BracketMinimum.
- Turn on conditional optimization in the case of usage of math_BFGS in the class math_GlobOptMin.
- Correct mistake in distmini command, which caused incorrect reading of deflection parameter.
- To avoid possible FPE signals, ensure initialization of fields in the class math/math_BracketMinimum.
- In the algorithms math_BFGS, math_Powell and math_FRPR, take into account that the function math_MultipleVarFunction can return failure status (e.g. when computing D0 out of bounds).

New test cases have been added.
Tests cases are updated.

// correct test case

42cf5bc1ca 0024002: Overall code and build procedure refactoring -- automatic
Automatic upgrade of OCCT code by command "occt_upgrade . -nocdl":
- WOK-generated header files from inc and sources from drv are moved to src
- CDL files removed
- All packages are converted to nocdlpack

0797d9d30a 0025418: Debug output to be limited to OCC development environment
Macros ending on "DEB" are replaced by OCCT_DEBUG across OCCT code; new macros described in documentation.
Macros starting with DEB are changed to start with "OCCT_DEBUG_".
Some code cleaned.
