Currently, mempools can only be allocated either using native DPDK memory, or anonymous memory. This patch will add two new methods to allocate mempool using external memory (regular or hugepage memory), and add documentation about it to testpmd user guide. It adds a new flag "--mp-alloc", with four possible values: native (use regular DPDK allocator), anon (use anonymous mempool), xmem (use externally allocated memory area), and xmemhuge (use externally allocated hugepage memory area). Old flag "--mp-anon" is kept for compatibility. All external memory is allocated using the same external heap, but each will allocate and add a new memory area.
