test: move to app directory
Since all other apps have been moved to the "app" folder, the autotest app
remains alone in the test folder. Rather than having an entire top-level
folder for this, we can move it back to where it all started in early
versions of DPDK - the "app/" folder.
This move has a couple of advantages:
* This reduces clutter at the top level of the project, due to one less
folder.
* It eliminates the separate build task necessary for building the
autotests using make "make test-build" which means that developers are
less likely to miss something in their own compilation tests
* It re-aligns the final location of the test binary in the app folder when
building with make with it's location in the source tree.
For meson builds, the autotest app is different from the other apps in that
it needs a series of different test cases defined for it for use by "meson
test". Therefore, it does not get built as part of the main loop in the
app folder, but gets built separately at the end.

Since compat library is only a single header, we can easily move it into
the EAL common headers instead of tracking it separately. The downside of
this is that it becomes a little more difficult to have any libs that are
built before EAL depend on it. Thankfully, this is not a major problem as
the only library which uses rte_compat.h and is built before EAL (kvargs)
already has the path to the compat.h header file explicitly called out as
an include path.
However, to ensure that we don't hit problems later with this, we can add
EAL common headers folder to the global include list in the meson build
which means that all common headers can be safely used by all libraries, no
matter what their build order.
As a side-effect, this patch also fixes an issue with building on BSD using
meson, due to compat lib no longer needing to be listed as a dependency.

net/sfc/base: move Tx descs number check to generic place
Now we have min/max limits in NIC config, so we can do check against
min/max in a generic place instead of NIC family specific functions.
Check that the descriptors number is a power of 2 is also can be made
common. It removes code duplication and makes NIC family
specific functions a bit shorter.

net/sfc/base: remove min define for number of Tx descs
EF100/Riverhead has different min limit. So, this limit should
be a part of NIC config, not define common for all NIC families.
Define maximum Tx descriptor number for Siena in the same way as
minimum for consistency.

net/sfc/base: report support for Tx checksum op descriptors
FreeBSD driver needs a patch to provide a means for packets
which do not need checksum offload but have flow ID set
to avoid hitting only the first Tx queue (which has been used
for packets not needing checksum offload).
This should be possible on Huntington, Medford or Medford2 chips
since these support toggling checksum offload on any given queue
dynamically by means of pushing option descriptors.
The patch for FreeBSD driver will then need a means to figure out
whether the feature can be used, and testing adapter family might
not be a good solution.
This patch adds a feature bit specifically to indicate support
for checksum option descriptors. The new feature bits may have
more users in future, apart from the mentioned FreeBSD patch.

Revise the external port calculation to support all

Logging should be supported in secondary process and now we have
everything required to share at least main logging macro.
sfc_adapter is going to become primary process only.

Start to factor out shared data into dedicated structure which will
