mdex_init, mtree_free - initialize and free a multicast index

       The mdex_init function initializes a multicast index.

       entries  gives  the  initial  number  of  entries  to  allocate.  This  is just a hint for initial memory
       allocation, and the index will be resized as required.

ENOMEM Not enough space/cannot allocate memory (POSIX.1-2001).

       mdex_init, mtree_free - initialize and free a multicast index

mdex_init() returns a pointer to a mdex_t handle, which should be freed by passing  to  mdex_free()  when
       done.  On error, NULL is returned, and errno is set to indicate the error.

       The mdex_free() function returns no value, and preserves errno.
