ethdev: add capability to keep shared objects on restart

rte_flow_action_handle_create() did not mention what happens
with an indirect action when a device is stopped and started again.
It is natural for some indirect actions, like counter, to be persistent.
Keeping others at least saves application time and complexity.
However, not all PMDs can support it, or the support may be limited
by particular action kinds, that is, combinations of action type
and the value of the transfer bit in its configuration.

Add a device capability to indicate if at least some indirect actions
are kept across the above sequence. Without this capability the behavior
is still unspecified, and application is required to destroy
the indirect actions before stopping the device.
In the future, indirect actions may not be the only type of objects
shared between flow rules. The capability bit intends to cover all
possible types of such objects, hence its name.

Declare that the application can test for the persistence
of a particular indirect action kind by attempting to create
an indirect action of that kind when the device is stopped
and checking for the specific error type.
This is logical because if the PMD can to create an indirect action
when the device is not started and use it after the start happens,
it is natural that it can move its internal flow shared object
to the same state when the device is stopped and restore the state
when the device is started.

Indirect action persistence across a reconfigurations is not required.
In case a PMD cannot keep the indirect actions across reconfiguration,
it is allowed just to report an error.
Application must then flush the indirect actions before attempting it.

ethdev: add capability to keep flow rules on restart

Previously, it was not specified what happens to the flow rules
when the device is stopped, possibly reconfigured, then started.
If flow rules were kept, it could be convenient for application
developers, because they wouldn't need to save and restore them.
However, due to the number of flows and possible creation rate it is
impractical to save all flow rules in DPDK layer. This means that flow
rules persistence really depends on whether PMD and HW can implement it
efficiently. It can also be limited by the rule item and action types,
and its attributes transfer bit (a combination of an item/action type
and a value of the transfer bit is called a rule feature).

Add a device capability bit for PMDs that can keep at least some
of the flow rules across restart. Without this capability behavior
is still unspecified and it is declared that the application must
flush the rules before stopping the device.
Allow the application to test for persistence of rules using
a particular feature by attempting to create a flow rule
using that feature when the device is stopped
and checking for the specific error.
This is logical because if the PMD can to create the flow rule
when the device is not started and use it after the start happens,
it is natural that it can move its internal flow rule object
to the same state when the device is stopped and restore the state
when the device is started.

Rule persistence across a reconfigurations is not required,
because tracking all the rules and configuration-dependent resources
they use may be infeasible. In case a PMD cannot keep the rules
across reconfiguration, it is allowed just to report an error.
Application must then flush the rules before attempting it.

build: enable AddressSanitizer

AddressSanitizer [1] a.k.a. ASan is a widely-used debugging tool to
detect memory access errors.
It helps to detect issues like use-after-free, various kinds of buffer
overruns in C/C++ programs, and other similar errors, as well as
printing out detailed debug information whenever an error is detected.

ASan is integrated with gcc and clang and can be enabled via a meson
option: -Db_sanitize=address
See the documentation for details (especially regarding clang).

Enabling ASan has an impact on performance since additional checks are
added to generated binaries.

Enabling ASan with Windows is currently not supported in DPDK.

ethdev: introduce shared Rx queue

In current DPDK framework, each Rx queue is pre-loaded with mbufs to
save incoming packets. For some PMDs, when number of representors scale
out in a switch domain, the memory consumption became significant.
Polling all ports also leads to high cache miss, high latency and low
throughput.

This patch introduces shared Rx queue. Ports in same Rx domain and
switch domain could share Rx queue set by specifying non-zero sharing
group in Rx queue configuration.

Shared Rx queue is identified by share_rxq field of Rx queue
configuration. Port A RxQ X can share RxQ with Port B RxQ Y by using
same shared Rx queue ID.

No special API is defined to receive packets from shared Rx queue.
Polling any member port of a shared Rx queue receives packets of that
queue for all member ports, port_id is identified by mbuf->port. PMD is
responsible to resolve shared Rx queue from device and queue data.

Shared Rx queue must be polled in same thread or core, polling a queue
ID of any member port is essentially same.

Multiple share groups are supported. PMD should support mixed
configuration by allowing multiple share groups and non-shared Rx queue
on one port.

Example grouping and polling model to reflect service priority:
Group1, 2 shared Rx queues per port: PF, rep0, rep1
Group2, 1 shared Rx queue per port: rep2, rep3, ... rep127
Core0: poll PF queue0
Core1: poll PF queue1
Core2: poll rep2 queue0

PMD advertise shared Rx queue capability via RTE_ETH_DEV_CAPA_RXQ_SHARE.

PMD is responsible for shared Rx queue consistency checks to avoid
member port's configuration contradict each other.

Cores count has a direct impact on the time needed to complete unit

Currently, the core list used for unit test is enforced to "all cores on

On the other hand, EAL default behavior (when no -c/-l option gets passed)

affinity.

Remove logic from meson: users can then select where to run the tests by
either running meson with a custom cpu affinity (using taskset/cpuset
depending on OS) or by passing a --test-args option to meson.
