Rewritten handling of declaration specifiers:
...
- Removed simplifyConst() because it did the opposite of the (superior) simplifyStaticConst()
- Execute simplifyStaticConst() in simplifyTokenList1() - there is no reason to defer it, and it is required to properly parse declarations like "unsigned static int i;"
- Fixed simplifyStaticConst() to handle more patterns. It did not work at the beginning of the token list and for function arguments
- Reimplemented Tokenizer::simplifyStdType()
-> properly support all possible ways to declare integers as requested by the standard, instead of only a few common permutations of "unsigned|signed", "short|char|long|int"

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.

Add a new test for OpenFile function from windows.cfg.
...
It is here as a reminder for a TODO. When used with OF_EXIST flag, the function OpenFile doesn't return a handle and thus, doesn't leak any resource.
As cppcheck doesn't support such feature yet, it's added a TODO not to be forgotten for later fix when cppcheck supports this.
Also added a naive check, just to ensure the OpenFile check doesn't get broken when adding support for OF_EXIST.
