[v2,00/25] cleanup ethdev close operation

  This is the end of a process started two years ago,
to have a close which reliably releases an ethdev port
without the need of removing the device (which can have more ports).

Unfortunately, some drivers might be broken because did not follow
the migration recommendations. We cannot wait more,
this should be merged before the 20.11-rc1 release.


v2 (big thanks to Ferruh for the reviews):
  - rebase on top of cxgbe updates
  - integrate updated patches for tap, bnx2x, qede
  - return 0 in atlantic PMD
  - fix failsafe mutex free
  - remove useless check in pcap
  - fix testpmd port state transition
  - add primary process check
  - reset more pointers in rte_eth_dev_release_port()
  - remove dev_started reset in rte_eth_dev_close()
  - return int from rte_eth_dev_close()

Note for future: fix old memory leak when releasing port,
i.e. free callbacks link_intr_cbs, post_rx_burst_cbs, pre_tx_burst_cbs.

The last 3 patches are optional changes to ethdev close/release
which were requested by Ferruh but may take longer to be accepted:
  - memset 0
  - keep start state
  - int return
