   Imake.tmpl.
 - Add FONT_DEFINES to ALLDEFINES.
 - Drop SpecialCObjectRules with FONT_DEFINES from various Imakefiles

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.

    record: avoid crash when calling RecordFlushReplyBuffer recursively

    RecordFlushReplyBuffer can call itself recursively through
    WriteClient->CallCallbacks->_CallCallbacks->RecordFlushAllContexts
    when the recording client's buffer cannot be completely emptied in one
    WriteClient. When a such a recursion occurs, it will not be broken out
    of which results in segmentation fault when the stack is exhausted.

    This patch adds a counter (a flag, really) that guards against this
    situation, to break out of the recursion.

    One alternative to this change would be to change _CallCallbacks to
    check the corresponding counter before the callback loop, but that
    might affect existing behavior, which may be relied upon.

The are now called reflecting their purpose:
viewport_scroll_left/up/right/down. This also regroups all the
keystrokes referring to viewport stuff.

Normal builds will not contain support for some keystrokes but warn
about unknown keystroke actions:

Info: ignoring unknown keystroke action 'debug_tree'.
Info: ignoring unknown keystroke action 'regions_on_screen'.
Info: ignoring unknown keystroke action 'test_input'.
Info: ignoring unknown keystroke action 'deactivate_input_devices_grab'.

So we remove those from the default keystrokes config.

no more late initialization

Some of the keystroke checks have used them before. This commit
unifies those checks.
