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.

4ddcde1e6f
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.

Use "enabled" list for the style checking.
...
Settings-class currently enables style checking via dedicated
boolean attribute. All other CLI's enable-options are handled
through the enable-list. This commit moves style-check enabling
to use the enable-list.
Main advantage is the consistency how options are handled/stored
in the Settings class. Which also unifies using them for the other
code. You need to enable certain type of checks? Use the
addEnabled()-method. You want to check if certain type of checks
are enabled? Use the isEnabled()-method.
