aa1b031274 get rid of warning C4800 under VS2010 
the "std::basic_ios::operator bool" differs between C++98 and C++11. The
"double not" syntax is portable and covers both cases with equivalent
meaning

f710d96602 Update ocl.cpp function Device::OpenCLVersion() 
Instead of CL_DEVICE_EXTENSIONS in Querying OpenCLVersion, it should be CL_DEVICE_VERSION flag which needs to be passed to the function.

5e4dfb9546 Change the argument type to cl_platform_info. 
Although both `cl_platform_info` and `cl_device_info` are defined as macro `cl_uint`, it needs to use `cl_platform_info` to get
the platform information.

4c7aa8645a ocl: validate arguments in KernelArgs constructor 
- don't use undefined flag=0. It should be CONSTANT instead.
- don't allow 'UMat* m=NULL' argument (except LOCAL/CONSTANT flags).
  This case is not handled well to provide NULL __global pointers.
  It is better to use '-D' macro defines instead (at least for performance)

c3a8db6d6c Merge pull request #7952 from mattmyne:JSONWriteFixTrailingDecimalPoint 
Append zero to trailing decimal place for FileStorage JSON write of a float or double value (#7952)

* Fix for FileStorage JSON write of a float or double value that has no fractional part; appends a zero character after the trailing decimal place to meet JSON standard.

* strlen return to size_t type rather than unnecessary cast to int
