Fixed cppcheck message found in lib:
...
[lib/checkmemoryleak.cpp:869]: (style) The scope of the variable 'realloc' can be reduced.
And since realloc is never used, for now I commented all the lines where 'realloc' is declared/used.

CheckMemoryLeak: two redundant assignments, should be clarified;
TemplateSimplifier: same;
Tokenizer: same.

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.

Replaced Tokenizer::getFunctionTokenByName() by SymbolDatabase::findFunctionByName(), which handles scopes slightly better.
