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)

Tokenizer::removeRedundantCondition: refactoring due to various reasons.
...
1) Remove the dead code with 'eraseDeadCode', not with 'eraseTokens' because of the possible presence of labels.
2) It's impossible that in tokenizer there is pattern like 'if (true|false) {code;} else if (cond) {code_cond;}' because the function 'Tokenizer::elseif' adds '{' between 'else' and 'if', hence a code path is redundant, so it's removed from code.

Fixed ticket #3557 (Tokenizer: simplification of '[]' doesn't work well):
...
extract undefined size array simplification and handle multiple arrays and combos between pointers and arrays, don't handle the definitions as arguments of function.

symbol database: add preliminary support for throw/catch block scopes. Just like the rest of cppcheck, ... is not handled properly for variables. Deep namespaces are also not handled properly yet. This is not an issue because this new capability is not used by any checks so it should be harmless.
