Replace master lcore with main lcore and

Keep the old functions and macros but mark them as deprecated

The "--master-lcore" command line option is also deprecated
and any usage will print a warning and use "--main-lcore"
as replacement.

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.

timer: add race condition test

Add new timer-manage race-condition test: We wrote a test to confirm
our suspicion that we could crash rte_timer_manage() under the right
circumstances. We repeatedly set several timers to expire at roughly
the same time on the master core. The master lcore just delays and runs
rte_timer_manage() about ten times per second. The slave lcores all
watch the first timer (timer-0) to see when rte_timer_manage() is
running on the master, i.e., timer-0's state is not PENDING.
At this point, each slave attempts to reset a subset of the timers to
a later expiration time. The goal here is to have the slaves moving
most of the timers to a different place in the master's pending-list,
while the master is traversing the same next-pointers (the slaves'
sl_next[0] pointers) and running callback functions. This eventually
results in the master traversing a corrupted linked-list.
In our observations, it results in an infinite loop.
