Remove the extra level of indirection via isc_memmethods_t
Previously, the applications using libisc would be able to override the internal memory methods with own implementation. This was no longer possible, but the extra level of indirection was not removed. This commit removes the extra level of indirection for the memory methods and the default_memalloc() and default_memfree().
