dc7ceda90f dispatch: Mark swapped dispatch as _X_COLD
This touches everything that ends up in the Xorg binary; the big missing
part is GLX since that's all generated code. Cuts about 14k from the
binary on amd64.

c833c0866f present: Handle event mask updates as specified v2
From the Present extension specification:

 An event context is associated with a specific window; using
 an existing event context with a different window generates
 a Match error.

 If eventContext specifies an existing event context, then if
 eventMask is empty, PresentSelectInput deletes the specified
 context, otherwise the specified event context is changed to
 select a different set of events.

 If eventContext is an unused XID, then if eventMask is empty
 no operation is performed. Otherwise, a new event context is
 created selecting the specified events.

Without this change, there's no way for a client to explicitly change
or destroy an existing event mask entry. Trying to do so as specified
above would just result in a protocol error.

v2: (Keith Packard)
* Use dixLookupResourceByType instead of walking window_priv->events
* Return BadMatch if the existing event context is associated with a
  different window or client
* Call LEGAL_NEW_RESOURCE again when creating a new event context
* Drop invalid "leak fix"

60014a4a98 Replace 'pointer' type with 'void *'
This lets us stop using the 'pointer' typedef in Xdefs.h as 'pointer'
is used throughout the X server for other things, and having duplicate
names generates compiler warnings.

We want to advertise the version we implement, not the version the
protocol headers happen to describe.
