In order to allow smooth addition of features without breaking
ABI compatibility, some space is reserved in several core structs

The struct rte_eth_dev and rte_eth_dev_data are supposed
to be used internally only, but there is a chance that
increasing their size would break ABI for some applications.

Add `rte_eth_dev_set_ptypes` function that will allow the application
to inform the PMD about reduced range of packet types to handle.
Based on the ptypes set PMDs can optimize their Rx path.
-If application doesn’t want any ptype information it can call
`rte_eth_dev_set_ptypes(ethdev_id, RTE_PTYPE_UNKNOWN, NULL, 0)`
and PMD may skip packet type processing and set rte_mbuf::packet_type to
RTE_PTYPE_UNKNOWN.
-If application doesn’t call `rte_eth_dev_set_ptypes` PMD can return
`rte_mbuf::packet_type` with `rte_eth_dev_get_supported_ptypes`.
-If application is interested only in L2/L3 layer, it can inform the PMD
to update `rte_mbuf::packet_type` with L2/L3 ptype by calling
`rte_eth_dev_set_ptypes(ethdev_id,
RTE_PTYPE_L2_MASK | RTE_PTYPE_L3_MASK, NULL, 0)`.

The dynamic mbuf fields were introduced by [1]. The egress metadata is
good candidate to be moved from statically allocated field tx_metadata to
dynamic one. Because mbufs are used in half-duplex fashion only, it is
safe to share this dynamic field with ingress metadata.
The shared dynamic field contains either egress (if application going to
transmit mbuf with tx_burst) or ingress (if mbuf is received with rx_burst)
metadata and can be accessed by RTE_FLOW_DYNF_METADATA() macro or with
rte_flow_dynf_metadata_set() and rte_flow_dynf_metadata_get() helper
routines. PKT_TX_DYNF_METADATA/PKT_RX_DYNF_METADATA flag will be set
along with the data.
The mbuf dynamic field must be registered by calling
rte_flow_dynf_metadata_register() prior accessing the data.
The availability of dynamic mbuf metadata field can be checked with
rte_flow_dynf_metadata_avail() routine.
DEV_TX_OFFLOAD_MATCH_METADATA offload and configuration flag is removed.
The metadata support in PMDs is engaged on dynamic field registration.
Metadata feature is getting complex. We might have some set of actions
and items that might be supported by PMDs in multiple combinations,
the supported values and masks are the subjects to query by perfroming
trials (with rte_flow_validate).

After removing the function rte_eth_dev_attach(),
there are two replacement solutions possible:
one using probe event notification, and one using a new iterator.
So the application can get the new probed ports either asynchronously
or synchronously.
The iterator API is new in DPDK 18.11 so they got the experimental
tag by policy. It causes an issue for strict applications which do
not use experimental functions, and want to use the synchronous method.
The replacement for removed API should not be experimental.
That's why the experimental status of the ethdev iterator is removed.

The iterator will return the ethdev port ids matching a devargs string.
It is recommended to use the macro RTE_ETH_FOREACH_MATCHING_DEV()
for usage convenience.
The class string is prefixed with '+' in order to skip the validation
of the parameter keys. It is tolerated for the compatibility with
the old (current) syntax where all parameters (bus, class and driver)
are mixed in the same string without any delimiter.
Thanks to this compatibility prefix, the driver parameters will be
skipped during the ethdev parsing, and not considered invalid.
A macro is introduced in rte_common.h to workaround a const field.
This hack is needed to free const strings in the iterator.
It is preferred to keep the const for these fields, because it gives
a hint that they are not changed at each iteration.
