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.

hash: remove deprecated function and macros

The function rte_jhash2() was renamed rte_jhash_32b and
macros RTE_HASH_KEY_LENGTH_MAX and RTE_HASH_BUCKET_ENTRIES_MAX
were tagged as deprecated, so they can be removed in 2.2.

RTE_HASH_KEY_LENGTH is replaced in unit tests by an internal macro
for the memory allocation of all keys used.

The library version number is incremented.

eal: add and use unaligned integer types

On machines that are strict on pointer alignment, current code breaks
on GCC's -Wcast-align checks on casts from narrower to wider types.
This patch introduces new unaligned_uint(16|32|64)_t types, which
correctly retain alignment in such cases. Strict alignment
architectures will need to define CONFIG_RTE_ARCH_STRICT_ALIGN in
order to effect these new types.

hash: update jhash function with the latest available

Jenkins hash function was developed originally in 1996,
and was integrated in first versions of DPDK.
The function has been improved in 2006,
achieving up to 35% better performance, compared to the original one.

This patch integrates that code into the rte_jhash library.
It also updates the precalculated hash values in the unit test,
as the code now returns different values (expected).

A final note has been added in release notes for stating
the changes made.
