-stored inside the SV but sv_usepvn allows the SV to use an outside string.
-The C<ptr> should point to memory that was allocated by C<malloc>. The
-string length, C<len>, must be supplied. This function will realloc the
-memory pointed to by C<ptr>, so that pointer should not be freed or used by
-the programmer after giving it to sv_usepvn. Does not handle 'set' magic.
