test/bonding: fix after hiding ethdev internal structures

link bounding auto-test internally creates emulated ethdev.
Some tests change Rx/Tx functions of this emulated device on the fly:
by directly modifying rte_eth_dev fields and without doing stop/start
for these devices.
As now ethdev uses rte_eth_fp_ops[] for fast-path functions, these
direct changes doesn't make expected effect.
Fix the problem by guarding fast-path functions changes with
rte_eth_dev_stop()/rte_eth_dev_start().

Fixes: 7a0935239b9e ("ethdev: make fast-path functions to use new flat array")

ethdev: remove underscore prefix from internal API

'_rte_eth_dev_callback_process()' & '_rte_eth_dev_reset()' internal APIs
has unconventional underscore ('_') prefix.
Although this is not documented most probably this is to mark them as
internal. Since we have '__rte_internal' flag to mark this, removing '_'
from API names.

For '_rte_eth_dev_reset()', there is already a public API named
'rte_eth_dev_reset()', so renaming '_rte_eth_dev_reset()' to
'rte_eth_dev_internal_reset'.

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.
