build DPDK libs and some drivers with meson/ninja

V3 changes:
* used two-digit version numbers when globally versioning libs+drivers
* removed symlinks with single-digit version numbers in same case
* moved driver install location from $prefix/dpdk to $prefix/share/dpdk

V2 changes:
* fixed copyright notices, updated 2016 to 2017
* removed dependency on kconfig file in kernel build tree
* marked pmdinfogen as a "native" binary, in preparation for future cross- compilation work
* added in additional warning flags for compatibility with existing system
---

Following on from the two previous RFCs [1] [2], here is a cleaned up patchset to serve as a start-point for getting all of DPDK building with meson and ninja.

What's covered:
* Basic infrastructure for feature detection and DPDK compilation
* Building of all DPDK libraries - as either static or shared
* Compilation of igb_uio driver for Linux
* Building a number of mempool, crypto and net drivers.
* Installation of compiled libraries and headers
* Installation of usertools scripts
* Compilation of testpmd as dpdk-testpmd and install of same
* Generation and installation of pkgconfig file for DPDK
* Contributors guide document addition describing how to add build scripts

What's not implemented:
* Just about everything else :-), including
* Support for non-x86 architectures, including cross-compilation
* Lots of PMDs
* Support for building and running the unit tests

Some key differences from RFC2:
* Removed duplication between the different driver meson files by moving the build logic up one level to the driver/meson.build file.
* Added a build option to allow versioning the libraries using the DPDK version number, rather than individual .so versions.
* Made EAL a default dependency for libs, to simplify meson.build files for a number of them.
* Made the build variables used for libraries and drivers more consistent.
* Moved responsibility for determining if a given driver or library should be built to the driver/library's own build file, giving a single place where all details about that component are placed, and saving having lots of environment detection logic in higher-level build files.
* Begun adding in developer documentation to make it easier for driver authors/maintainers to contribute.

Meson 0.41 and ninja are needed, and ideally meson 0.42 is recommended. Ninja is available in most distributions, and meson - if an updated version is not available on your distro of choice - can be easily got using
"pip3 install meson"

To build and install then use:

meson build # use default compiler and shared libs cd build
ninja
sudo ninja install

Thereafter to use DPDK in other build systems one can use:

	pkg-config --cflags DPDK
	pkt-config --libs DPDK

to query the needed DPDK build parameters.

Once reviewed and tested a bit, I hope to apply this set - or a new revision of it - to the build-next tree, to serve as a baseline for others to use and to add the missing functionality to.

Regards,
/Bruce
