linux: xf86OpenConsole: Don't detach from controlling tty when it is our vt

Detaching from our controlling tty makes little sense when it is the same
as the vt we're asked to run on. So automatically assume -keeptty in this case.

This is useful to do because when not running as root the server can only make
various VT related ioctls when it does not detach from the tty.

xf86Xinput: Modify API for server-managed fd support

With systemd-logind support, the xserver, rather than the drivers will be
responsible for opening/closing the fd for input devices.

This commit adds a new capabilities field to the InputDriverRec and a
XI86_DRV_CAP_SERVER_FD flag for drivers to indicate that they support server
managed fds.

This commit adds a new XI86_SERVER_FD flag to indicate to drivers when the
server is managing the fd and they should not open/close it. Note that even
if drivers declare they support server managed fds there is no guarantee they
will actually get them.

Since this changes the input driver ABI, this commit bumps it.

systemd-logind tracks devices by their chardev major + minor numbers, since
we are breaking ABI anyways also add major and minor fields for easy storage /
retrieval of these.

systemd-logind: Add systemd-logind "core"

This commits add the bulk of the systemd-logind integration code, but does
not hook it up yet other then calling its init and fini functions, which
don't do that much.

Note the configure bits check for udev since systemd-logind use will only be
supported in combination with udev. Besides that it only checks for dbus
since all communication with systemd-logind is happening over dbus, so
no further libs are needed.

systemd-logind: Add delayed input device probing

With systemd-logind we cannot probe input devices while switched away, so
if we're switched away, put the pInfo on a list, and probe everything on
that list on VT-Enter.

This is using an array grown by re-alloc, rather than a xorg_list since
creating a new data-type to store a pInfo + list-entry just for this seems
overkill.

config-udev: Don't try to add drm devices twice

Before this commit we were trying to add most drm devices twice, once
from xf86platformProbe() and once from config_udev_init().

This results in somewhat confusing messages in Xorg.log, ie:

(II) xfree86: Adding drm device (/dev/dri/card0)
Later followed by:
(II) config/udev: Adding drm device (/dev/dri/card0)

By filtering out duplicate drm devices we avoid these confusing messages.
