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://stackoverflow.com/q/6461487
http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2160.html

- 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

Small refactoring to compile more matches
...
*** Timing of the test suite ***
Four runs were used to calculate the average run time.
Before: ~1,103s
After: ~1,066s
Speed up: 3,35%
*** Timing of internal projects using STL ***
Before: ~8,301s
After: ~8,207s
Speed up: 1,13%
So the real world speed up is roughly 1%.

Adapt Tokenizer::simplifyCallingConvention() and Tokenizer::simplifyKeyword() for the match compiler
...
This little change gives another 6% speed improvement on my box.
(tested with the testsuite and checking the 'rpm' codebase)
The profiler showed we were spending quite some time in
Tokenizer::simplifyCallingConvention(). The multi match
pattern in there is "complex", at least for the on-the-fly parser.

- 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 "

Properly implement %op% for Token::multiCompare
...
Use tok->isOp() instead of doing it "manually".
This fixes false positives for the C++ template case since
the brackets in "template < something >" are not comparison operators.
Profiling showed using tok->isOp() is actually faster than before (-O2).

Change location of %op% operator in multicompare

of a multicompare, it properly executes Token::isOp().
Otherwise it uses it's "internal implementation".
Workaround inspired by Edoardo Prezioso.

Also, the arguments can be also multitokens, so that it's possible to simplify, for example: 'sin^2(k())+cos^2(k())=1'.

Use more Effective C++ code style in Token class:
...
1)The non-const version of Token::tokAt and Token::linkAt now will use a combination of const_cast and static_cast to remove duplicate code.
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.

Tokenizer: some changes to the code:
...
be sure '?:' ternary operation has whitespaces around the operators;
remove useless loop to get the 6 next tokens, use tokAt(6);
add '?1:0' to bool values when doing a sum with them.
remove useless 'enum' pattern checking in code executed after simplifyEnum;
after being sure the 'tok' is a standard type, begin the loop with the token next to it;
it's possible to remove two tokens before the current one without moving this.

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.

Refactoring information messages.
...
Currently the information severity messages are outputted as error
messages with Severity::Information. This causes constant confusion
as people think it as mildest error severity (and rightfully so).
When it was meant to be for printing messages about the checking
procedure itself (like missing header files etc).
So I'm adding a new function for the ErrorLogger for printing these
informative messages. This makes clear the distinction of errors
found from the code and messages related to the checking itself.
It also makes it easier for clients to handle these separately.

Implemented support for building cppcheck lib into a dll
...
Updated VS9 solution
New VS10 solution that builds cppcheck into a dll used by cli and testrunner.
Functional changes and advantages of new solution:
- Share code between testrunner and cli; ability to share code with gui as well (not yet implemented)
- Files of /lib are no longer compiled twice (should improve build time on single core machines)
- Added configuration for building with PCRE support
- Executables are build into /bin (/bin/debug in debug mode) folder (Should no longer require rebuild when switching between debug and release)
- Completely x64 compatible (contains also x64-debug configuration now)

- Reduced distance given to tokAt calls in CheckStl::redundantCondition
- Rearranged code in CheckStl::missingComparison to use more efficient comparision of varIds instead of variable names. Use varId in pattern instead of variable name.
