Make it possible to capture GLXBufferSwapComplete events

DRI2 clients don't receive GLXBufferSwapComplete events on the wire.
Instead the event is synthesized by the DRI2 WireToEvent handler,
so for an application to be able to see it we have to convert the
synthetic event to an xcb_glx_buffer_swap_complete_event_t and pass
it to the native event filter.

QPlatformMenu: add MenuType enum

On mobile platforms several different popup menu types exist.
E.g on iOS, you have a special popup just for selecting text.
This patch will add a new enum that lets UI controls select/hint
which one to use for a particular QPlatformMenu. It's likely
that the enum needs to be extended later (DropdownMenu, PopoverMenu
etc), but being able to specify the edit menu at least will do for now.

QFutureInterface: allow to work with a QThreadPool != globalInstance()

Background:
It is often necessary/advisable to schedule tasks on thread pools !=
globalInstance(). As Herb Sutter writes in
http://www.drdobbs.com/parallel/use-thread-pools-correctly-keep-tasks-sh/216500409
and the Qt Training Material stresses, tasks you schedule on a (global)
thread pool should be non-blocking, which currently rules out using any of
the QtConcurrent functions for, say, file I/O.

Nonetheless it's often convenient to have thread pools also for file I/O, as
the thumbnail viewer exercise in the Qt Training Material shows. In this
case, you'd use a dedicated thead pool, leaving the global thread pool for
CPU-bound tasks.

Yet, none of the QtConcurrent functions allow to pick the QThreadPool
instance on which to schedule the work created with them.

This patch prepares for them to do so.

This is the first part of the forward-port of
https://qt.gitorious.org/qt/qt/merge_requests/1281.

Implement by using a new QThreadPool* member that defaults to nullptr,
and adding setThreadPool to set this member, then using it in lieu of
QThreadPool::globalInstance() everywhere.

I chose to leave m_pool == nullptr to mean globalInstance() to avoid
creating the global instance whenever a QFuture is created, even if the
future represents the result of a calculation not run on the global thread
pool.

[ChangeLog][QtCore][QFuture] Can now be used with any QThreadPool, not
just globalInstance().
