Huisong Li 02edbfab1e ethdev: add dev configured flag
Currently, if dev_configure is not called or fails to be called, users
can still call dev_start successfully. So it is necessary to have a flag
which indicates whether the device is configured, to control whether
dev_start can be called and eliminate dependency on user invocation order.

The flag stored in "struct rte_eth_dev_data" is more reasonable than
 "enum rte_eth_dev_state". "enum rte_eth_dev_state" is private to the
primary and secondary processes, and can be independently controlled.
However, the secondary process does not make resource allocations and
does not call dev_configure(). These are done by the primary process
and can be obtained or used by the secondary process. So this patch
adds a "dev_configured" flag in "rte_eth_dev_data", like "dev_started".

libabigail raised a warning on this change.
This change is fine wrt ABI as far as we understand, but we can't
express an exception rule (see libabigail bug #28060) to waive the
changes only in this part of the rte_eth_dev_data struct.
The solution for now is to globally waive any change on the
rte_eth_dev_data structure.
