docs: better docs, mv doxygen to sphinx

This patch refactors the VPP sphinx docs
in order to make it easier to consume
for external readers as well as VPP developers.

It also makes sphinx the single source
of documentation, which simplifies maintenance
and operation.

Most important updates are:

- reformat the existing documentation as rst
- split RELEASE.md and move it into separate rst files
- remove section 'events'
- remove section 'archive'
- remove section 'related projects'
- remove section 'feature by release'
- remove section 'Various links'
- make (Configuration reference, CLI docs,
  developer docs) top level items in the list
- move 'Use Cases' as part of 'About VPP'
- move 'Troubleshooting' as part of 'Getting Started'
- move test framework docs into 'Developer Documentation'
- add a 'Contributing' section for gerrit,
  docs and other contributer related infos
- deprecate doxygen and test-docs targets
- redirect the "make doxygen" target to "make docs"

Type: refactor

+Release notes for VPP 16.09
+===========================
+
+Features
+--------
+
+-  `Integrated July 2016 DPDK release <http://www.dpdk.org/doc/guides/rel_notes/release_16_07.html>`__
+
+   -  DPDK-vhost is depreciated pending a complete rework of the
+      original integration and addressing of rx performance deltas.
+   -  Patches required for DPDK 16.07:
+
+      -  Correctly setting the Packet Type in the IGB, IXGBE and i40e
+         drivers.
+      -  Correctly setting checksum in the i40e driver.
+      -  NXP DPAA2 PMD Driver.
+      -  rte_delay (yield) functionality.
+
+-  Add “in tree” plugins:
+
+   -  IPv6 ILA.
+   -  iOAM.
+   -  Load Balancer.
+   -  SNAT.
+
+-  High-performance (line-rate) “neutron like” L4 port-filtering.
+
+-  API refactoring - addressing some of the issues around JVPP bindings.
+
+   -  Accommodating plugins
+      `(e.g. NSH_SFC) <https://wiki.fd.io/view/NSH_SFC>`__
+   -  Binding for `python <https://wiki.fd.io/view/VPP/Python_API>`__
+
+-  LISP
+
+   -  L2 LISP overlays
+   -  Multitenancy
+   -  Multihoming
+   -  RTR mode
+   -  Map-resolver failover algorithm
+
+-  Support 64-bit vector lengths, huge shared-memory segments.
+
+-  Dynamic IP Feature ordering
+
+   -  IP Features can now specify features they appear before and after
+
+-  16.09 Builds
+
+   -  Ubuntu 14.04 LTS - Trusty Tahr
+   -  Ubuntu 16.04 LTS - Xenial Xerus
+   -  CentOS 7
+   -  More information on `VPP wiki <https://wiki.fd.io/view/VPP/Installing_VPP_binaries_from_packages>`__
+
+-  Performance, characterize and document performance for this release
+   `(more information on CSIT page) <https://wiki.fd.io/view/CSIT>`__
+
+   -  IPv4 and IPv6 Scale - performance tests.
+
+      -  Bidirectional 10k/100k/1M flows.
+      -  64B,570B, 1518B,9000B packet sizes.
+
+   -  IPv6 iACL - performance
+
+      -  DUT1 and DUT2 are configured with IPv6 routing, two static IPv6
+         /64 routes and IPv6 iAcl security whitelist ingress /64 filter
+         entries applied on links.
+      -  TG traffic profile contains two L3 flow-groups (flow-group per
+         direction, 253 flows per flow-group) with all packets
+         containing Ethernet header, IPv6 header and generated payload.
+         MAC addresses are matching MAC addresses of the TG node
+         interfaces.
+
+   -  L2XC VXLANoIPv4 - performance
+
+      -  DUT1 and DUT2 are configured with L2 cross-connect. VXLAN
+         tunnels are configured between L2XCs on DUT1 and DUT2.
+      -  TG traffic profile contains two L3 flow-groups (flow-group per
+         direction, 253 flows per flow-group) with all packets
+         containing Ethernet header, IPv4 header with IP protocol=61 and
+         generated payload. MAC addresses are matching MAC addresses of
+         the TG node interfaces.
+
+-  Documentation
+
+   -  Autogenerated CLI documentation.
+   -  Using doxygen to automate API/Node documentation.
+   -  `(available online) <https://docs.fd.io/vpp/16.09/>`__
