#5805 'Passing value -1.0 to sqrt() leads to undefined result' is incorrect. Degrade wrongmathcall from error to warning, since it deals with implementation-defined behaviour

Disabled several checks and simplifications for C code, if they are C++-only. Do not match arguments for C code, since there can't be overloads.

Reimplemented version.h:
...
- Use macros to form version number and string. CPPCHECK_MAJOR, CPPCHECK_MINOR and CPPCHECK_DEVMINOR now contain the parts of the version number.
- "dev" status is now detected by comparison of CPPCHECK_MINOR and CPPCHECK_DEVMINOR, version string created accordingly.
Fixed two comments.
