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.
