[00/10] enhance meson summary - list disabled components

  After using meson to configure a build, we output a brief list of all
components that are enabled. However, of more use to most users is a
list of what is not being enabled, so that they can look for gaps and
see about fixing those gaps, e.g. by installing driver dependencies.

This patchset adds such a printout at the end, but to make things
easier, it also adds support for drivers adding a reason why they not
being built, e.g. unsupported platform, or missing software dependency.

Example output from a FreeBSD platform, for which many drivers do not
compile:

Ping on this patchset. It's acked almost 2 weeks now, so can it be merged?
[to get it off my "list-of-stuff-to-track"]
