[Buildroot] [PATCH 0/11 v7] Introduce libudev (branch yem/libudev3)

[Yann E. MORIN]

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 the last two developers days, it was suggested that libudev was
to be made a virtual package that could be selected (like jpeg is). I
tried doing so, but I did not like the outcome of this. See my comments
on my previous attempt:
    http://lists.busybox.net/pipermail/buildroot/2014-December/115455.html

Since I am not really interested in libudev all by itself (and I was
taking care of it just to get something clean), and am not either
motivated to maintain this series forever, it was decided at the last
developers days that I should respin the series and that Peter would take
over to conclude this work.

So be it. ;-)

The series contains:

  - a patch to fix generating the list of virtual packages for the manual

  - three patches to introduce the libudev virtual package, and its
    providers: eudev and systemd

  - a patch to make eudev only build libudev if /dev management is
    handled by neither eudev nor systemd

  - four patches to convert packages to depend on libusb instead of a
    udev daemon; those packages have been confirmed by Bernd to indeed
    only need libudev and not a udev daemon

  - five RFC patches to convert packages we are not sure whether they
    would be happy with only a libudev, and which would need run-time
    testing to check

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.

Yann E. MORIN.
