Move ADMA2 stuff to extra header and unit. Move ESDHCv2 implementations to
extra unit. Use exceptions instead of error codes. Clean-up documentation.
Ref #1497
The manual termination of multi-block writes via "Stop Transmission" commands
seems to leave the card in a busy state sometimes. This causes errors on
subsequent commands. Thus, we have to synchronize manually with the
card-internal state via "Send State" commands. Additionally, the method
for issuing the manual "Stop Transmission" commands was refined.
Ref #1497
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.

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.

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.
For each session upgrade performed by a wm client as part of the
Nitpicker::Connection::buffer function, the window manager wrongly
upgraded the wrapped nitpicker session twice: Once by handling the
Root::upgrade, and again by handling of the server-side 'buffer'
operation. Here, the 'buffer' operation was implemented by not merely
forwarding the RPC request to the wrapped nitpicker session but by
calling the 'buffer' method on the wrapped session's connection
object, which implictly issues session upgrades. Consequently,
the window manager would transfer twice the amount of the session
upgrades it received by its clients to nitpicker and eventually ran
out of memory.
The patch fixes the problem by eliminating the call of the
Nitpicker::Connection::buffer method and instead merely forward the RPC
requests to the wrapped nitpicker sessions.
The original version of the icon painter would reach beyong the
texture boundaries for textures of even width and height, and when
painting an icon with the width or height of the texture.
In this case, p3 would be set to the same value as p2. However, the code
expects p3 to lie within the middle rectangle. However, in this corner
case, the middle rectangle is actually empty. So no pixel can lie within
it. Hence, p3 is positioned by one pixel to the left outside the middle
rectangle, which violates the assumptions when calculating the clipping
and texture offsets. The patch fixes the problem by reducing the size of
the right column by one pixel. This ensures that exists always a
non-zero middle rectangle.
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.
'block_for_signal' and 'pending_signal' now set pending flag in signal context
in order to determine pending signal. The context list is also used by the
'Signal_receiver' during destruction.
Fixes#1738
Instead of just red messages in the log and a hanging caller, the issuer
may respond to it - e.g. a noux bash shell will show an error and is
afterwards still usable.
Fixes#1778
Accidentally removed by #1658. We need to make the cleanup call for server
objects - otherwise we may get in capability identifier re-use trouble.
