ivs: get build id from the environment

This fixes the build id for builds outside of a git repo (such as when building
debian packages).
Merge into master from pull request #6:
ivs: get build id from the environment (https://github.com/floodlight/ivs/pull/6)
ivs: fix build id displayed in log
ivs: add --tunnel option

Not all users need flow-based tunneling support. Since it adds some complexity
this change disables it by default.

Fixes XE-50.
Merge into master from pull request #7:
add --tunnel option to IVS (https://github.com/floodlight/ivs/pull/7)
README: expand section on building debian packages

Removed "make install" instructions because its behavior may be surprising
compared to standard autoconf projects.
add libpcap-dev dependency to setup.sh and README
add INTERNALS.md

This document is for details useful to new developers but too in depth for the
README.
OVSDriver: use CFR when checking for overlapping kflows

With the introduction of the meta_id match fields the OVS flow key is no longer
a superset of the OpenFlow match. This broke ind_ovs_kflow_invalidate_overlap,
which translated the kflow key into an of_match and compared it with the
of_match sent by the controller (which may have had the meta_id fields
un-wildcarded).

The fix, which should also be more performant, is to translate the of_match and
kflow key into a CFR.
