   2  * SETUP: Make sure we define everything we will need.
   3  *
   4  * We have create three types of pools:
   5  *   1) MEMPOOL - standard pools
   6  *   2) MALLOC_MEMPOOL - to be used by mem_malloc in mem.c
   7  *   3) PBUF_MEMPOOL - a mempool of pbuf's, so include space for the pbuf struct
   8  *
   9  * If the include'r doesn't require any special treatment of each of the types
  10  * above, then will declare #2 & #3 to be just standard mempools.
