Hello All!

Big fat warning: this is only an RFC for now!

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 anudev daemon. That's the case for e.g. libinput, libcec,
mesa3d...

The series contains:

  - a patch to remove a spurious dependency on udev for XBMC

  - three patches to fix generating the list of virtual packages for
    the manual

  - two patches to remove the prompts of eudev and systemd, since
    they are never user-selectable; a bit of cleanup is done in the
    dependencies as well

  - a patch to intrduce the libudev virtual package

  - two patches to add libudev providers: eudev and systemd

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

  - ten patches to convert packages to depend on libusb instead of a
    udev daemon

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.

Also, the converted packages have not been tested, not even build-tested;
this is just an RFC to validate the overal solution for now.

On your keyboards, get set, ready... Comment! :-)

Changes RFCv1 -> RFCv2:
  - have eudev and systemd be providers for libudev, instead of having
    udev be the provider  (Thomas, on IRC)
  - fix the manual lists after bugs were uncovered with the removal of
    the eudev and systemd prompts
  - convert some packages

Regards,
Yann E. MORIN.
