Remove const qualifier from the argument of free() and realloc(),
as well as in numerous other variables that hold ownership of memory.

By convention, a pointer that holds ownership is _never_ qualified by const.
This is reflected in the standard type signature of free() and realloc().
Allowing const pointers to hold ownership may seem superficially convenient,
but is actually quite confusing to experienced C programmers.
