Seth Howell 5d57386885 env_dpdk: spdk_mem_map_translate informs user of translation size.
This function will now check for whether or not a memory region is
contiguous accross 2MB map entries and return the total length of that
contiguous buffer up to the size specified by the user.

Also includes unittests
This series of changes is aimed at enabling spdk_mem_map_translate to
report back to the user the length of the valid mem_map up to the
function that requested the translation.
This will be useful when retrieving memory regions associated with I/O
buffers in NVMe-oF. For large I/O it will be possible that the buffer is
split over multiple MRs and the I/O will have to be split into multiple
SGLs.
