[Buildroot] [PATCH 00/12 v8] Introduce libudev (branch yem/libudev-4)

[Yann E. MORIN <yann.morin.1998@free.fr>]

Hello All!

This series introduces the possibility to just build and install
libudev, without requiring that the /dev management be handled by
eudev or systemd.

A lot of packages that have a dependency on udev, in fact only require a
libudev, not a udev daemon. That's the case for e.g. libinput, libcec,
mesa3d...

During previous developers days, it was suggested that libudev was to be
made a virtual package that could be selected (like jpeg is). So I
eventually got some time to rework it (since the series was not adopted
by Peter as it was discussed during those DevDays:
https://lite5.framapad.org/p/buildrootfosdem15 ;-) ).

This series is a full rewrite from scratch, with very little caried over
from the previous attempts (far back in the past).

  - first come a few cleanup patches;

  - then eudev is split in two, virtually providing to different
    packages in one, with two different configure/build/install
    procedures, one for libudev only, one for the full package;

  - then the libudev virtual package is introduced, with eudev and
    systemd both declared as providers;

  - libudev is made selectable, so that packages can select it instead
    of depending (like is usual) on the virtual package;

  - eventually, two packages are converted over to using libudev:
    qt5base, as an optional implicit dependency, and libinput, as a
    mandatory dependency.

Not all packages that reference udev have been switched over to depend
on libudev, though, since it is unclear to me whether they require a
udev daemon, or would be happy with just libudev. This can be done in
follow up patches once libudev is eventually in the tree (for good this
time I hope! ;-) )


Changes v7 -> v8:
  - total rewrite
  - libudev is selectable

Yann E. MORIN.
