[PATCH on-demand v4] systemd socket activation code for xserver

[Łukasz Stelmach]

Hi.

These patches have been discussed already[1][2][3]. Time has passed
and I'd like to ask you to look at them once again.I've rebased them onto
respective origin/master branches and checked if all the recommended
fixes are in place. If you find anthing I can improve, your comments
are more than welcome. I will be glad to make this code good enough to
be merged and publish as a part of Xorg.

The following three patches:

+ libxtrans 1/2: Define TRANS_RECEIVED flag for transports
+ libxtrans 2/2: Enable systemd socket activation
+ xserver 1/2: configure.ac: enable systemd socket activation in
  libxtrans

hold the essential code for on-demand starup. The fourth

+ xserver 2/2: Do not define ErrorF in xstrans.c, libxtrans handles it.

is just a minor fix to remove a few warning messages.
