When checking C++ compatibility of SDK headers,
an error is detected by the compiler:
lib/dmadev/rte_dmadev_pmd.h:95:23: error:
‘RTE_DEV_NAME_MAX_LEN’ undeclared here (not in a function)
The header file rte_dev.h must be included.

dmadev: add flag for error handling support
Due to HW or driver limitations, not all dmadevs may support full error
handling e.g. safely managing and reporting an invalid address to a copy
operation. The skeleton dmadev, for example, being pure software will
always seg-fault if passed an invalid address. To indicate the
availability of safe error handling by a device, we add a capability
flag for it.

dmadev: add burst capacity API
Add a burst capacity check API to the dmadev library. This API is useful to
applications which need to how many descriptors can be enqueued in the
current batch. For example, it could be used to determine whether all
segments of a multi-segment packet can be enqueued in the same batch or not
(to avoid half-offload of the packet).
