 - Move FONT_DEFINES and XLIBFONT definition to from Server.tmpl to
   Imake.tmpl.
 - Add FONT_DEFINES to ALLDEFINES.
 - Drop SpecialCObjectRules with FONT_DEFINES from various Imakefiles
   again, FONT_DEFINES is now set "globally".
 - Hand over FONT_DEFINES from main Makefile to nx-X11's make BuildEnv

    Add CreatePixmap allocation hints.

    These hints allow an acceleration architecture to optimize allocation of certain
    types of pixmaps, such as pixmaps that will serve as backing pixmaps for
    redirected windows.

Makefile: Tell Xserver build which Xfont API to use (v2 or v1) depending on what's available in the build env.

 Fixes ArcticaProject/nx-libs#296.

 Inspired by the following X.org commit. Other than X.org, we will continue
 support for building nx-libs against libXfont1 for a while.

    dix: Switch to the libXfont2 API (v2)

    This new libXfont API eliminates exposing internal X server symbols to
    the font library, replacing those with a struct full of the entire API
    needed to use that library.

    v2: Use libXfont2 instead of libXfont_2

    SetFontPath: set client->errorValue on failure.

    Previously the callers were only setting errorValue on Success, when
    it's ignored, and leaving it alone on failure, when it's sent to the
    client.

    Since SetFontPath takes the ClientPtr, let it set client->errorValue
    instead of letting the callers continue to get it wrong.

    dix: Move InitFonts up above screen initialization

    Font initialization was split into two stages, the first was to set up
    font privates with a call to ResetFontPrivateIndex, then much later
    the call to InitFonts to set up all of the FPEs. Doing the full font
    initialization before initializing the video drivers means that we can
    move the call to ResetFontPrivateIndex inside InitFonts.

        xserver: remove index from CloseScreen (API/ABI breakage)

        This drops the index from the CloseScreen callback,
        its always been useless really, since the pScreen contains it.
