cppcheck-1.58

Cppcheck-1.58 has been released.

Commandline/Settings changes:
- Added --include to the cppcheck command line client. This forces inclusion of the given file. This can for instance be used instead of --append and will then allow you to use #define etc also.
- The threads handling has been improved. Using -jN now works in windows also.

Improvements:
- NULL pointers: Improved checking of default function argument values.

For those who compile Cppcheck: you can improve the speed by using compiled patterns.
When compiling with the Makefile, use "SRCDIR=build".
When compiling with VS you have to manually use the python script to generate the code.
Please ask in the chat if you have questions.

Additionally, lots of false positives have been fixed.
