[0/6] meson build improvements

  These patches make some improvements to the meson build, particularly
for documentation. They also remove many, but not all warnings issued by
meson e.g. warnings about newer features unsupported in baseline.

The biggest change is to improve the handling of the guide html docs.
The change here is more significant, and the doc build now uses a
wrapper script around sphinx. This wrapper script allows us to output
correct dependency information for the sphinx build in a .d file. This
.d file is processed by ninja (not meson) on build, so that any changes
to doc files trigger a rebuild to the guides using sphinx.

For now, the two patches which remove the meson version warnings are
CC'ed to stable for backport, theoretically this who set could be
backported if so desired, as all changes could be considered fixes to
some degree or other, and nothing introduces a whole new feature.

Note: for completeness and simplicity, previously submitted patch
http://patches.dpdk.org/patch/64189/ is included in this set, and will
be marked superceded in patchwork.
