729f471b9e dix: move alwaysCheckForInput declaration to first use
Move the declaration of alwaysCheckForInput closer to where it is first
used and initialize it at declaration rather than assigning it later.

f4115e69eb dix: initialize all screens before proceeding to gc's, root windows etc
Current code walks along all screens and initializes screen resources,
then gc's, stipples, root windows for each of them, hence after
the first screen registering new private keys is no more possible.
This crashes modesetting driver if it is not initialized before others.

This patch makes screen resources for all screen initialize first, hence
all necessary private keys (including of the type PRIVATE_WINDOW) are
initialized before root windows are created.

b0f94e1c5c dix: add CreateScreenResources callback mechanism
Right now, extensions that need to be called after the CreateScreenResources
proc had been run, must wrap the screen proc vector directly (all of them
forming kind of daisy chain), and so - when called - temporarily restore the
previous one, call it, wrap again, and if the call was successful finally
doing it's own stuff. (same is done for many other procs)

While that approach is looking nice and elegant on the drawing board, it's
complicated, dangerous like a chainsaw and makes debugging hard, leading to
pretty blurred API borders.

Instead introducing a simple approach for letting extension hook into a
post-CreateScreenResources callback list safely, w/o having to care much
about side effects with the call chain. Extensions now can simply register
their business logic and get called back - w/o ever having to mess with the
ScreenRec's internal structures.

Note that these hooks are executed *AFTER* the original CreateScreenResources()
proc had been called SUCCESSFULLY (returned TRUE), so callees can rely on
the DDX/driver had already done it's job.

b0a09ba602 dix: keep a ref to the rootCursor
CreateCursor returns a cursor with refcount 1 - that refcount is used by
the resource system, any caller needs to call RefCursor to get their own
reference. That happens correctly for normal cursors but for our
rootCursor we keep a variable to the cursor despite not having a ref for
ourselves.

Fix this by reffing/unreffing the rootCursor to ensure our pointer is
valid.
