acl: fix build and runtime for default target

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

- keep common code shared between these two codepaths.

because previous Ubuntu kernel 3.13.0-29.53, already based on 3.13.11, needs to

Similarly, UBUNTU_KERNEL_CODE is generated with ABI and upload numbers.

`lsb_release -si` is first used to check whether we are running Ubuntu
`lsb_release -sr` provides release number 14.04, then converted to integer 1404
/proc/version_signature is parsed to get base kernel version, ABI and upload
numbers, and flavour is dropped

UBUNTU_KERNEL_CODE is indirectly defined using the UBUNTU_KERNEL_VERSION macro,
which in turn is defined in kcompat.h
This makes a single place to define the Ubuntu kernel version numbering scheme,
which is slightly different than the usual "shift by 8" scheme: ABI numbers can
be big (see: https://wiki.ubuntu.com/Kernel/Dev/TopicBranches), so 16-bits have
been reserved for them.

Finally, the implementaion of skb_set_hash is skipped in kcompat.h if we are
running Ubuntu 14.04 with an Ubuntu kernel >= 3.13.0-30.54

eal: map shared config into exact same address as primary process

Shared config is shared across primary and secondary processes.
However,when using rte_malloc, the malloc elements keep references to
the heap inside themselves. This heap reference might not be referencing
a local heap because the heap reference points to the heap of whatever
process has allocated that malloc element. Therefore, there can be
situations when malloc elements in a given heap actually reference
different addresses for the same heap - depending on which process has
allocated the element. This can lead to segmentation faults when dealing
with malloc elements allocated on the same heap by different processes.

To fix this problem, heaps will now have the same addresses across
processes. In order to achieve that, a new field in a shared mem_config
(a structure that holds the heaps, and which is shared across processes)
was added to keep the address of where this config is mapped in the
primary process.

Secondary process will now map the config in two stages - first, it'll
map it into an arbitrary address and read the address the primary
process has allocated for the shared config. Then, the config is
unmapped and re-mapped using the address previously read.
