vhost: remove vhost-net requirements from generic APIs

The rte_vhost API to put data into virtqueues operates
on mbufs and hence it is strictly vhost-net specific.
External backends need to implement virtqueue handling
from scratch and that's just not possible without APIs
to get/set vring base addresses.

Those relevant APIs are there, but they have a check that
prevents them from working with any non-vhost-net device.
This patch removes those checks.

rte_vhost_get_log_base() is not necessarily needed for
external backends, as other, higher level vhost APIs for
live migration are available and could be used instead.

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

Since compat library is only a single header, we can easily move it into

this is that it becomes a little more difficult to have any libs that are

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

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
