NXAGENT_UPGRADE code cleanup:

 NX agent contains/ed two build trees. An old one (probably pre-3.x.y)
 and a "newer" one. The "newer" code tree used to become enabled by
 setting NXUpgradeAgentServer in nx-X11/config/cf/host.def to YES.

 As building the NXUpgradeAgentServer has been the default for
 years now, we drop all code that does not get used at build time
 for NXUpgradeAgentServer == YES (i.e., the code that belongs to the
 pre-3.x.y phase of NX agent).

-    this code is highly unlikely.  it is not haile selassie.

-    there is some hair here.  we can't just use the window's
-clip region as it is, because if we are painting the border,
-the border is not in the client area and so we will be excluded
-when we validate the GC, and if we are painting a parent-relative
-background, the area we want to paint is in some other window.
-since we trust the code calling us to tell us to paint only areas
-that are really ours, we will temporarily give the window a
-clipList the size of the whole screen and an origin at (0,0).
-this more or less assumes that ddX code will do translation
-based on the window's absolute position, and that ValidateGC will
-look at clipList, and that no other fields from the
-window will be used.  it's not possible to just draw
-in the root because it may be a different depth.
-
-to get the tile to align correctly we set the GC's tile origin to
-be the (x,y) of the window's upper left corner, after which we
-get the right bits when drawing into the root.
-
-because the clip_mask is being set to None, we may call DoChangeGC with
-fPointer set true, thus we no longer need to install the background or
-border tile in the resource table.
