The functions and structures are moved to app/test in order to keep
existing unit tests. Some minor changes were done in these functions
because of library scope restrictions.
An enum is also copied in two other applications to keep existing code.
The library version is incremented.

This is a duplication of some EAL parts for a standalone packaging
which is not documented.
Packaging should be done outside of DPDK.

If at build phase we don't make any trie splitting,
then temporary build structures and resulting RT structure might be
much bigger than current.
>From other side - having just one trie instead of multiple can speedup
search quite significantly.
>From my measurements on rule-sets with ~10K rules:
RT table up to 8 times bigger, classify() up to 80% faster
than current implementation.
To make it possible for the user to decide about performance/space trade-off -
new parameter for build config structure (max_size) is introduced.
Setting it to the value greater than zero, instructs rte_acl_build() to:
- make sure that size of RT table wouldn't exceed given value.
- attempt to minimise number of tries in the table.
Setting it to zero maintains current behaviour.
That introduces a minor change in the public API, but I think the possible
performance gain is too big to ignore it.

CACHE_LINE_SIZE is a macro defined in machine/param.h in FreeBSD and
conflicts with DPDK macro version.
Adding RTE_ prefix to avoid conflicts.
CACHE_LINE_MASK and CACHE_LINE_ROUNDUP are also prefixed.

Make ACL library to build/work on 'default' architecture:
- make rte_acl_classify_scalar really scalar
(make sure it wouldn't use sse4 instrincts through resolve_priority()).
- Provide two versions of rte_acl_classify code path:
rte_acl_classify_sse() - could be build and used only on systems with sse4.2
and upper, return -ENOTSUP on lower arch.
rte_acl_classify_scalar() - a slower version, but could be build and used
on all systems.
- Addition of a new function rte_acl_classify_alg. This function lets you
specify an enum value to override the acl contexts default algorithm when doing
a classification. This allows an application to specify a classification
algorithm without needing to publicize each method. I know there was concern
over keeping those methods public, but we don't have a static ABI at the moment,
so this seems to me a reasonable thing to do, as it gives us less of an ABI
surface to worry about.
- keep common code shared between these two codepaths.
