In Xinerama/Panoramix configuration there's one screen that's having special
meaning - it's used for simulating as the frontend for all client operations:
the clients (should) only talk to that screen, while panoramix subsystem is
proxying those operations to all the other screens (with certain changed
applied, eg. coordinate transformations).
Historically, this screen happens to be the first one in the system (some of
it's proc's are hooked up in order to achieve desired behaviour). That's why it
used to be accessed via screenInfo.screens[0] - that already had been encapsulated
into a tiny helper `dixGetFirstScreen()`.
a) the correct terminus technicus for a situation where one device (or SW entity)
entirely controlling others is a master-slave-relationship: the controlling
device/entity is `master`, the controlled ones are `slave` (to that specific
master).
b) the term "first screen" is inacurate and misleading here: what the caller's are
actually interest in isn't the first entry in the screen array, but the screen
that's controlling the others. With upcoming refactoring of the Xinerama/Panoramix
subsystem, this might well be a different array index than 0.
c) the term `default` also wouldn't match: `default` implies there's a real practical
choice, and such value applies when no explicit choice has been made. But in this
case, it practically doesn't make sense (except perhaps for debugging purpose)
for a client to use any different screen.
Therefore fixing the function name to the correct technical terminology.
(for sake of patch readability, renaming corresponding variables is left to
subsequent patches).

Instead of everybody directly accessing the (internal) screenInfo struct,
let those consumers only interested in first screen use a little helper.
Also caching the value if it's needed several times.

Using calloc() instead of malloc() as preventive measure, so there
never can be any hidden bugs or leaks due uninitialized memory.
The extra cost of using this compiler intrinsic should be practically
impossible to measure - in many cases a good compiler can even deduce
if certain areas really don't need to be zero'd (because they're written
to right after allocation) and create more efficient machine code.
The code pathes in question are pretty cold anyways, so it's probably
not worth even thinking about potential extra runtime costs.

The symbol controls whether to include dix-config.h, and it's always set,
thus we don't need it (and dozens of ifdef's) anymore.

InitPointerClassDeviceStruct/InitKeyboardDeviceStruct allocate a
proximity/focus class, respectively. If a driver calls
InitFocusClassDeviceStruct or InitProximityClassDeviceStruct beforehand,
the previously allocated class is overwritten, leaking the memory.
Neither takes a parameter other than the device, so we can simply skip

Many references to the WindowTable array already had the corresponding
screen pointer handy, which meant they usually looked like
"WindowTable[pScreen->myNum]". Adding a field to ScreenRec instead of
keeping this information in a parallel array simplifies those
expressions, and eliminates a MAXSCREENS-sized array.
Since dix uses this data, a screen private entry isn't appropriate.
xf86-video-dummy currently uses WindowTable, so it needs to be updated
to reflect this change.

Configure a server that uses the keyboard driver with an invalid ruleset,

"off" in the ServerFlags or ServerLayout section. Start the server.
After failing to init the keymap, the server will try to clean up after the
device, double-freeing some xkb structs that have not been reset properly.
