cb056611a8 eal: rename lcore master and slave
Replace master lcore with main lcore and
replace slave lcore with worker lcore.

Keep the old functions and macros but mark them as deprecated
for this release.

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

There is a common macro __rte_unused, avoiding warnings,
which is now used where appropriate for consistency.

a9de470cc7 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.

7d3b1ec47f test: move unit tests to separate directory
This is to logically group unit tests into their own folder,
separating them from "app" folder.

Hopefully this will make the unit test in DPDK more visible.

Following binaries moved to "test" folder:
cmdline-test
test-acl
test-pipeline
test            <-- various DPDK unit tests

26e09db6cb app/test: rework command registration
The tests are registered with their command name by adding a structure
to a list. The structure of each test was declared in each test file
and passed to the register macro.
This rework generate the structure inside the register macro.

a0fd91cefc mempool: rename functions with confusing names
The mempool_count and mempool_free_count behaved contrary to what their
names suggested. The free_count function actually returned the number of
elements that were allocated from the pool, not the number unallocated as
the name implied.

Fix this by introducing two new functions to replace the old ones,
* rte_mempool_avail_count to replace rte_mempool_count
* rte_mempool_in_use_count to replace rte_mempool_free_count

In this patch, the new functions are added, and the old ones are marked
as deprecated. All apps and examples that use the old functions are
updated to use the new functions.

4b5062755a mempool: allow user-owned cache
The mempool cache is only available to EAL threads as a per-lcore
resource. Change this so that the user can create and provide their own
cache on mempool get and put operations. This works with non-EAL threads
too. This commit introduces the new API calls:

    rte_mempool_cache_create(size, socket_id)
    rte_mempool_cache_free(cache)
    rte_mempool_cache_flush(cache, mp)
    rte_mempool_default_cache(mp, lcore_id)

Changes the API calls:

    rte_mempool_generic_put(mp, obj_table, n, cache, flags)
    rte_mempool_generic_get(mp, obj_table, n, cache, flags)

The cache-oblivious API calls use the per-lcore default local cache.

449c49b93a mempool: support handler operations
Until now, the objects stored in a mempool were internally stored in a
ring. This patch introduces the possibility to register external handlers
replacing the ring.

The default behavior remains unchanged, but calling the new function
rte_mempool_set_ops_byname() right after rte_mempool_create_empty() allows
the user to change the handler that will be used when populating
the mempool.

This patch also adds a set of default ops (function callbacks) based
on rte_ring.

2465980ad2 app/test: decrease size of requested mempool
In test application, the default size of allocated mempool is calculated
as following:

  (RTE_MAX_LCORE * (RTE_MEMPOOL_CACHE_MAX_SIZE + max_kept_objects)) - 1

The objective is to ensure that all cores can fill their cache and keep
'max_kept_objects' at the same time. As RTE_MAX_LCORE is 128 and
RTE_MEMPOOL_CACHE_MAX_SIZE is 512 in the default configuration, it can
produce very large mempools (170 MB).

We can replace the number of core by a dynamic value, which drastically
reduces the amount of memory needed for this test (5 MB with 4 cores).

591a9d7985 add FILE argument to debug functions
The DPDK dump functions are useful for remote debugging of an
applications. But when application runs as a daemon, stdout
is typically routed to /dev/null.

Instead change all these functions to take a stdio FILE * handle
instead. An application can then use open_memstream() to capture
the output.
