Fix SEGV on Solaris x86

On Solaris x86, with both GCC 4.8 and 4.9, running cppcheck causes a segmentation fault when process terminates.
The backtrace (dbx) where

The destructor order is somehow getting messed up on this platform.
This fix moves the code away from header file and ensures _instances remains valid during termination.

Refactorizations optimizing std::string usage:
...
1) Added global static const std::string emptyString; object:
-> Replaces some static variables in functions which might be not threadsafe
-> Avoids constructor call (std::string::string(""))
-> Even functions that return an empty string in some branches can return by reference now.
Added to config.h to ensure that it is available everywhere
2) Added overloads for TestFixture::assertEquals for the most common use cases:
-> Moves conversion from const char[] to std::string into a function, reducing code duplication in binary.

Cleaned up includes and forward declarations in checkers:

- Removed unused includes
