doc: announce renaming of mbuf offload flags

Browse Source 
The mbuf offload flags do not match the DPDK namespace (they are
not prefixed by RTE_). Announce their rename in 21.11, and the
removal of the old names in 22.11.

A draft coccinelle script is provided to anticipate what the
renaming will be.

``__atomic_thread_fence`` must be used for patches that need to be merged in
20.08 onwards. This change will not introduce any performance degradation.
* mbuf: The mbuf offload flags ``PKT_*`` will be renamed as ``RTE_MBUF_F_*``.
A compatibility layer will be kept until DPDK 22.11, except for the flags
that are already deprecated (``PKT_RX_L4_CKSUM_BAD``, ``PKT_RX_IP_CKSUM_BAD``,
``PKT_RX_EIP_CKSUM_BAD``, ``PKT_TX_QINQ_PKT``) which will be removed.
* pci: To reduce unnecessary ABIs exposed by DPDK bus driver, "rte_bus_pci.h"
will be made internal in 21.11 and macros/data structures/functions defined
in the header will not be considered as ABI anymore. This change is inspired
