Andrew C. Martin bd0d9b9639 fix misspellings & gcc v3.4.6 warnings
1.  fix typos / misspellings
 - Fix misspelling within comments, variable/function names, stdout messages
 - changes the name of an error code: ```stlBoundries``` changed to ```stlBoundaries```.  Alias old name (```stlBoundries```) to the new one.

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

 - fixes gcc v3.4.6 warnings, except for those in tinyxml and "-Wmissing-declarations" makefile 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:

http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2160.html
http://stackoverflow.com/q/670308

 - in the codebase before and after this change, testrunner SEGVs in a number of places on gcc v3.4.6, including ```Check::~Check()```, among others
   - fc42fc95 fixes this particular runtime issue for DJGPP & __sun

Andrew C. Martin 4a73c93750 Fix compiler warnings and comment/string typos
- fix g++ warning:

> lib/checkother.cpp:3779: warning: comparison between signed and unsigned integer expressions

 - fix suncc warning (see [everything2](http://everything2.com/title/C%252B%252B%253A+static+extern+%2522C%2522)):

> "lib/checkmemoryleak.cpp", line 578: Warning (Anachronism): Formal argument __compar of type extern "C" int(*)(const void*,const void*) in call to bsearch(const void*, const void*, unsigned long, unsigned long, extern "C" int(*)(const void*,const void*)) is being passed int(*)(const void*,const void*).

- prefer empty() / isEmpty() over "size() > 0" (cases not caught by stlSize)

- fix word misspellings (mostly comments, a few output lines)

  - Parenthesis => Parentheses (both variations were used in the codebase)

  - fix typo and wording ("never alwayw") in gui/test/data/benchmark/simple.cpp's CheckOther::unsignedPositive():

```
-  "An unsigned variable will never alwayw be positive so it is either pointless or "
+  "An unsigned variable can't be negative so it is either pointless or "
```

Edoardo Prezioso 8e1e8525a3 Partial rewrite of Tokenizer::simplifyComma:
skip '= { .. }' where possible;
hence remove '%num% after comma' check because it's redundant now;
replace round braces counter method with faster 'link skip';
if 'endAt' is 'NULL' after finding the ';' token, exit the function;
hence remove redundant 'tok != NULL' check after simplifying 'return' code.

PKEuS 35d94c26d5 Changed creation of SymbolDatabase. Database always created after Tokenizer::tokenize() and Tokenizer::simplifyTokenList() instead of on-demand creation by Tokenizer::getSymbolDatabase.
-> With Token::scope() it is possible to access the symboldatabase without having to call getSymbolDatabase(). The change increases safety because it is guaranteed that the database is available in all checks, even if the specific check doesn't call getSymbolDatabase
- Tokenizer::_symbolDatabase does no longer have to be mutable -> Increased const correctness

The change above required two additional changes:
- A bug causing a debug message was fixed in the symboldatabase that became visible in the test suite by the change above.
- Simplify expressions like "struct struct Foo" which might be result of typedef instanciation.
