Rather than relying on the target machine architecture, use the
size of a pointer from the compiler to determine if we are 64-bits

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.

In rte_vhost_driver_unregister(), the connection fd is
removed from the fdset using fdset_try_del(). Call to

executing the read or write callback on this fd.
When it happens, rte_vhost_driver_unregister() keeps
trying to remove the fd from the set until it is no

This situation is causing a deadlock, because
rte_vhost_driver_unregister() keeps trying to remove
the fd from the set with vhost_user.mutex held, while
the callback executed by the dispatcher,
vhost_user_read_cb(), also takes this mutex at

At that time we don't know the maximum packet size yet because it is

Check the maximum packet length at device configure time, because then we
