e904fd77d8 dmadev: add missing header include
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.

223e0f7244 dmadev: remove symbol versioning for inline helpers
Inline helpers have no global symbols in shared libraries.
There is no reason to ask for versioning (plus this library would not
build on Windows).

c61c8282ef dmadev: hide devices array
No need to expose rte_dma_devices out of the dmadev library.
Existing helpers should be enough, and inlines make use of
rte_dma_fp_objs.

2e348d8fe3 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.

ea8cf0f853 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).

5e0f859127 dmadev: add channel status check for testing use
Add in a function to check if a device or vchan has completed all jobs
assigned to it, without gathering in the results. This is primarily for
use in testing, to allow the hardware to be in a known-state prior to
gathering completions.
