We have to issue a data synchronization barrier after writing a ADMA2
table to ensure that the corresponding write commands were actually
executed before issuing the SD command.
Ref #1497
On i.MX53 QSB, a "Send Op Cond" command during the driver initialization
returns another response value than on the USB Armory. As the check for
this response seems to have no relevance for the driver functionality (Linux
reads the value from MMIO but I can't find a place in the source code where
it is used), we simply remove it.

Previously, it was not necessary to acknowledge an IRQ initially before using
it. However, since the IRQ framework changed lately it is. Adapt to this.
Ref #1497
Notify client initially to enforce a client-side ROM update. Otherwise,
a server-side ROM update between session creation and signal-handler
registration would go unnoticed.
Issue #1788
This patch changes the decorator to always apply stacking-order changes
immediately instead of deferring the re-stacking of the nitpicker views
to the next call of 'update_nitpicker_views'. The deferred application
did not always work when more then one windows changed their stacking
position at once because the cached '_neighbor' values interfered with
each other.
The eager re-stacking should not have negative effects on the user
experience because, in contrast to re-positioning, re-stacking a rare
operation.
This change makes it possible to reuse the generic window decorator
classes in include/decorator/ for decorators of a different structure.
E.g., instead of painting decorations on a single nitpicker session,
each window may paint its decorations into additional window-specific
nitpicker sessions.
In the event where a nitpicker session's quota was depleted by the
allocation of view handles, nitpicker would abort. The patch prevents
the abort by reflecting this condition as an Out_of_metadata exception
to the client. This way, the client can upgrade its session as needed.
The problem was triggered by running the decorator_stress test (changed
to generate 40 windows) with the themed_decorator.
This patch addresses the corner case that the specified neighbor view
is the first view of the view stack. If this is the case when inserting
the view in front of the neighbor (behind == false), the target position
within the view stack must be a null pointer, not the first view.
Because the conditions have become rather complicated, both cases
of 'behind' are handled separately now.
The notion of a channel is shared by the mixer backend as well as the
frontend. To make dealing with reports between those easier move the
Channel definition to a global header.
Issue #1770.
This patch ensures that focus changes performed via the Session::focus
call are made effective the next time, the user is idle. Previously,
focus changes during drag operations were simply discarded.
