/**
* @brief Define a memory pool
*
* This declares and initializes a memory pool whose buffer is aligned to
* a @a align -byte boundary. The new memory pool can be passed to the
* kernel's memory pool functions.
*
* Note that for each of the minimum sized blocks to be aligned to @a align
* bytes, then @a min_size must be a multiple of @a align.
*
* @param name Name of the memory pool
* @param min_size Minimum block size in the pool
* @param max_size Maximum block size in the pool
* @param n_max Number of maximum sized blocks in the pool
* @param align Alignment of the memory pool's buffer
