Add FIB library support for IPv6.

Add FIB (Forwarding Information Base) library. This library
implements a dataplane structures and algorithms designed for
fast longest prefix match.
Internally it consists of two parts - RIB (control plane ops) and
implementation for the dataplane tasks.
Initial version provides two implementations for both IPv4 and IPv6:
dummy (uses RIB as a dataplane) and DIR24_8 (same as current LPM)
Due to proposed design it allows to extend FIB with new algorithms
in future (for example DXR, poptrie, etc).

Add RIB (Routing Information Base) library. This library
implements an IPv4 routing table optimized for control plane
operations. It implements a control plane struct containing routes
in a tree and provides fast add/del operations for routes.
Also it allows to perform fast subtree traversals
(i.e. retrieve existing subroutes for a given prefix).
This structure will be used as a control plane helper structure
for FIB implementation. Also it might be used standalone in other
different places such as bitmaps for example.
Internal implementation is level compressed binary trie.

Running dpdk-pmdinfo.py on Ubuntu 18.04 (bionic) with python 3 and
pyelftools installed produces no output but no error is reported
neither:
~$ python3 usertools/dpdk-pmdinfo.py -r build/app/testpmd
~$ echo $?
0
While with python 2, it works:
~# python2 usertools/dpdk-pmdinfo.py -r build/app/testpmd
{"pci_ids": [], "name": "dpio"}
{"pci_ids": [], "name": "dpbp"}
{"pci_ids": [], "name": "dpaa2_qdma"}
.....
On Ubuntu 18.04, pyelftools is version 0.24. The change log of
pyelftools v0.24 says:
- Symbol/section names are strings internally now, not bytestrings
(this may affect API usage in Python 3) (#76).
We cannot guess which version of pyelftools is actually being used. The
elftools.__version__ symbol is not consistent with each distro's package
version. For example, on Ubuntu 16.04 (xenial), the .deb package version
is '0.23-2' but elftools.__version__ contains '0.25'. This is certainly
due to partial backports.
To have a more consistent behaviour of this script across all versions
of python, add the unicode_literals future import so that literal
strings are now always "unicode".
Add 2 utility functions to force a string into bytes or bytes into an
unicode string.
Force pyelftools return values to unicode strings (will do nothing with
recent version of pyelftools).
If elffile.get_section_by_name returns None with a unicode section name,
try with the same one encoded as bytes.
Also, replace all open() calls by io.open() which behaves like the
builtin open in python 3. The only non-binary opened file is
/usr/share/hwdata/pci.ids which is UTF-8 encoded text. Explicitly
specify that encoding.

The cache-misses problem is very serious when the function
lpm_cb_parse_ptype is called to read the content of packets. That is
because the contents of packages previously stored in the cache are
overwritten by the following instructions or variables.
Thus the prefetch order can be used to prefetch the next packet into
the cache to avoid CPU spending too much time on it.
On Octeon TX platform with built-in NIC, 12% performance gain was
measured by running RFC2544 NDR test with l3fwd. Furthermore, the
cache-misses event of the function lpm_cb_parse_ptype was reduced by
20%, and the CPU task-clock of it dropped from 16.49% to 11.3%, based
on the forwarding test for one minute with the 64B packet.
On the dpaa2 platform, no performance improvement nor drop were seen
with this patch by running RFC2544 NDR test with l3fwd.
On the x86 platform, 15.7% performance gain was measured by running
RFC2544 NDR test with l3fwd.

The ether header does not need to be packed since that makes no sense for
structures with only bytes in them, but it should be aligned to a two-byte
boundary to simplify access to it from code. Other packed structures that
use this also need to be updated to take account of the change, either by
removing packing - where it is clearly unneeded - or by explicitly giving
those structures 2-byte alignment also.
