Subject: dix: add whiteroot flag

Before there was no way of getting a white background despite having
the approriate code.

Backport of this commit:

  commit cb0a565d2b2cf8823abbd77b4426cc2237731dc1
  Author: Daniel Stone <daniel@fooishbar.org>
  Date:   Fri Aug 18 17:04:48 2006 +0300

    dix: add whiteroot flag
    Add a -wr option to use a white root window, and use a BackPixel rather
    than BackPixmap for both white and black root windows.

Subject: Splash.c: do not wait in nxagent mode

The splash window is only shown in x2go mode. In nxagent mode the
splash window was also shown, but empty (and thus invisible). And the
code waited for the splash window to disappear. Fix this by skipping
_all_ the splash stuff in nxagent mode.

Subject: nxagent: drop nxagentRootTileWindow

We either use a solid black or a white background and no backround
pixmap. So nxagentRootTileWindow is always empty and we can drop all
stuff around it.

remove nxagentSplashCount, too, since it is no longer checked anywhere.
