Improve handling of realloc in memory leak checker (#3036) 
Mark realloced variables as realloced instead of freed. This allows
improved checking for code with error realloc handling.

If cppcheck finds an if-statement which checks the validity of the
allocated memory or resource, check if the memory/resource is
reallocated from another variable. If so, we can add checking of that
variable in the if-statement instead. This allows to check that variable
for memleaks and double frees.

This fixes #9292 and #9990 which both concern FPs with double frees
after correct error handling.

cppcheckdata: Use instance attributes in Cppcheckdata (#3029) 
This commit makes CppcheckData class to use instance attributes instead
of class attributes.

Since class attributes are mutable (list), when you append to them, they
don't promote to instance variable which means when you call parsedump()
multiple times data just gets appended to them.
