no more need to pass down a struct, we now only pass the milliseconds
and let the function do the rest.

The effect of this was that special keystrokes where detected and
passed to the nxagent. E.g. pressing ctrl-alt-f for Fullscreen also
produced an "f" in the current input window inside the nxagent.

With the removal of the Ipaq code there's no path anymore to open the
onscreen keyboard. Also nxkbd is not available and we do not have
tested that feature with any onscreen keyboard yet. So there's no
point in integrating that code.

Fixes ArcticaProject/nx-libs#405

Did we ever provide a binary?

This is a bit weird, I'd expect far more places where the compiler
could complain about Window vs Window64... But it does not.

Screen.c:306:32: warning: passing argument 3 of ‘XQueryTree’ from incompatible pointer type [-Wincompatible-pointer-types]
   if (XQueryTree(d, candidate, &root, &parent, &children, &num_children))

../../../../exports/include/nx-X11/Xlib.h:3041:5: note: in expansion of macro ‘Window’

This fixes problems with kwin and compiz when using the
switch-all-screens keystroke. The fullscreen would appear shortly and
then vanish again.

Fixes ArcticaProject/nx-libs#458

We can only free the xkbDevicePrivate because we do not know the
details of any other (possible) extension. So let's limit to that one
private for now and call the new xkbFreePrivates from dix (where such
a function is completely missing).

there's more work to do...

The whole nx-X11/extras dir is no longer checked since we only have
Mesa there and we do not want to check that mess...

All the exceptions in static-analysis-suppressions have been manually
checked.

[nx-X11/programs/Xserver/record/set.c:361]: (warning) Possible null pointer dereference: stackIntervals

stackIntervals is only NULL if nIntervals is 0, too. In that case
memcpy will do nothing and so it is ok to pass NULL as source. But it
is ugly nevertheless...

    xkb: Silence some compiler warnings

    Of the form:

    ../xkb/XKBGAlloc.c: In function ‘SrvXkbAddGeomKeyAlias’:
    ../xkb/XKBGAlloc.c:591:13: warning: ‘strncpy’ specified bound 4 equals destination size [-Wstringop-truncation]

                 ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    This is intentional; the code that reads from these fields never reads
    more than 4 bytes anyway. Rephrase things in terms of memcpy so that's
    clear. Obviously this is awful but in XKB awful is par.

    XKB: Remove a bunch of mad ifdefs

    We have SEEK_SET and size_t, seriously.  Also use DebugF instead of

    xkb: remove oldState from XkbHandleActions.

    I really don't know what the purpose of this variable is or was, aside from
    potentially clobbering up our key state since there's a path where it may be
    used uninitialised.

    Also, this means that xkbi->prev_state is now accessible from the DIX with
    meaningful data.

Move allocation of image_index close before first_use. This way we do
not need to free it if previous step fail. And we cannot forget that
free() call.

While at it replace malloc+memset by calloc.
