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"
-> Fixed parsing of _Complex/complex types

2. fix gcc v3.4.6 32bit & 64bit warnings

- in Preprocessor::handleIncludes(), replace a ```vector <bool>``` with ```stack<bool>``` (see ```vector<bool>``` warning below).
- this is the only ```vector<bool>``` in the codebase
- ```vector <bool>``` is actually a case of template specialization, and is not recommended, according to the following links:

2)The non-const versions of Token::find(simple)match are added, in order to avoid the usage of const_cast outside the Token code.
3)As a consequence of 2), an useless const_cast applied to a call of Token::findsimplematch in Tokenizer code is removed.

1)Implement another declaration of 'Token::eraseTokens' with parameters: the starting token and the number of times needed to call 'deleteNext'.
...
2)Use the overloaded 'eraseTokens' where needed instead of using consecutively 'deleteNext'.
3)Tokenizer: general optimizations about the deletion of some tokens.
4)Run astyle.

"Internal error. Token::Match called with varid 0." didn't work when error was in a header file. Fixed that.

"Internal error. Token::Match called with varid 0." will now cause check to abort and write a proper error log with filename. Previously filename was empty and format was always xml.

1)Add 'Token' function 'linkAt', which simplifies the writing 'tokAt(i)->link()' to 'linkAt(i)'.
...
It's still unused, though.
2)Fix one grammatical mistake inside token.h
3)Style change to token.cpp: remove the whitespace between '!' and 'begin'.

Also contains test order improvements from Johan Samuelson (#3116 ).

Benchmarked using these settings:
- CXXFLAGS="-O2 -g -NDEBUG"
- time -p cppcheck.git -q --std=posix --enable=all --inconclusive -Dfoo .

Fix single %op% operator not working at all
...
When parsing the Token::Match pattern, we accesed
the wrong character in the pattern and never
executed the %op% check.
In addition the unit test function for %op%
wasn't registered in the test suite. Ups.
All fixed now and also provide a complete
check for all operators %op% supports.

Fixed #1132 (Detection of misused scope objects)
...
Emits error in the form:
[useless_lock.cpp:18]: (error) instance of "Lock" object destroyed immediately
...if an instance of a class or struct is unnamed and therefore destroyed
straight after creation.
Removed "internal error" from token.cpp, since in this case varid would be NULL.
