Wrappers around the free, malloc and calloc functions but
called from inside the library. Required by some systems
to handle multiple-HEAPs and pass memory to and from the library.

<p>
Free memory allocated inside raptor.
</p>
<p>
Some systems require memory allocated in a library to
be deallocated in that library. This function allows
memory allocated by raptor to be freed.
</p>
<p>
Examples include the result of the '_to_' methods that returns
allocated memory such as raptor_uri_filename_to_uri_string,
raptor_uri_filename_to_uri_string
and raptor_uri_uri_string_to_filename_fragment</p>
