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 "

CheckMemoryLeak: add '?1:0' to clarify the value of the argument to 'deleteNext'; Tokenize.cpp: in simplifyCompoundAssignment(), remove ':' odd code used to fix a weird test case ('case' code not inside a function body), remove useless 'tok->next() != NULL' check (already true by previous condition); in simplifyConditionOperator(), handle better the parenthesis skipping code and remove useless ')'check; in simplifyQuestionMark(), remove useless 'tok->tokAt(-2)' check (Token::Match returns false if the token is NULL), add more patterns to Token::Match to handle more test cases; in simplifyBitFields(), add 'const' to 'offset' bool. RedirectOutputError: style nitpick change to declaration of a pointer.
