As discussed on the dpdk-dev mailing list[1], we can make some easy
improvements in standardizing the naming of the various components in DPDK,
and their associated feature-enabled macros.
Following this patch, each library will have the name in format,
'librte_<name>.so', and the macro indicating that library is enabled in the
build will have the form 'RTE_LIB_<NAME>'.
Similarly, for libraries, the equivalent name formats and macros are:
'librte_<class>_<name>.so' and 'RTE_<CLASS>_<NAME>', where class is the
device type taken from the relevant driver subdirectory name, i.e. 'net',
'crypto' etc.
To avoid too many changes at once for end applications, the old macro names
will still be provided in the build in this release, but will be removed
subsequently.

this case following the "bus" directory, we can simplify somewhat the build

than having it's build distributed across 3 folders.
This also opens up the possibility of building the QAT driver with crypto
only and the compression part disabled. It further allows more sensible

build: add defines for compatibility with make build
The defines used to indicate what crypto, compression and eventdev drivers
were being built were different to those used in the make build, with meson
defining them with "_PMD" at the end, while make defined them with "_PMD"
in the middle and the specific driver name at the end. This might cause
compatibility issues for applications which used the older defines, which
switching to build against new DPDK releases.
As well as changing the default to match that of make, meson also
special-cases the crypto/compression/event drivers to have both defines
provided. This ensures compatibility for these macros with both meson and
make from older versions.
For a selection of other libraries and drivers, there were other
incompatibilities between the meson and make-defined macros which were not
previously highlighted in a deprecation notice, so we add per-macro
compatibility defines for these to ease the transition from make to meson.

with 0 buffers in single mode were ignored and not passed to the
legacy algorithm implementation causing lack of synchronization.
This patch fixes this issue by passing NULL as buffer which is
a valid way of sending just synchronization handshakes
in single mode.

test/distributor: fix shutdown of busy worker
The sanity test with worker shutdown delegates all bufs
to be processed by a single lcore worker, then it freezes
one of the lcore workers and continues to send more bufs.
The freezed core shuts down first by calling
rte_distributor_return_pkt().
The test intention is to verify if packets assigned to
the shut down lcore will be reassigned to another worker.
However the shutdown core was not always the one, that was
processing packets. The lcore processing mbufs might be different
every time test is launched. This is caused by keeping the value
of wkr static variable in rte_distributor_process() function
between running test cases.
Test freezed always lcore with 0 id. The patch stores the id
of worker that is processing the data in zero_idx global atomic
variable. This way the freezed lcore is always the proper one.

distributor: handle worker shutdown in burst mode
The burst version of distributor implementation was missing proper
handling of worker shutdown. A worker processing packets received
from distributor can call rte_distributor_return_pkt() function
informing distributor that it want no more packets. Further calls to
rte_distributor_request_pkt() or rte_distributor_get_pkt() however
should inform distributor that new packets are requested again.
Lack of the proper implementation has caused that even after worker
informed about returning last packets, new packets were still sent
from distributor causing deadlocks as no one could get them on worker
side.
This patch adds handling shutdown of the worker in following way:
1) It fixes usage of RTE_DISTRIB_VALID_BUF handshake flag. This flag
was formerly unused in burst implementation and now it is used
for marking valid packets in retptr64 replacing invalid use
of RTE_DISTRIB_RETURN_BUF flag.
2) Uses RTE_DISTRIB_RETURN_BUF as a worker to distributor handshake
in retptr64 to indicate that worker has shutdown.
3) Worker that shuts down blocks also bufptr for itself with
RTE_DISTRIB_RETURN_BUF flag allowing distributor to retrieve any
in flight packets.
4) When distributor receives information about shutdown of a worker,
it: marks worker as not active; retrieves any in flight and backlog
packets and process them to different workers; unlocks bufptr64
by clearing RTE_DISTRIB_RETURN_BUF flag and allowing use in
the future if worker requests any new packets.
5) Do not allow to: send or add to backlog any packets for not
active workers. Such workers are also ignored if matched.
6) Adjust calls to handle_returns() and tags matching procedure
to react for possible activation deactivation of workers.
