44fe44e8b6 init: invalidate child-provided service on kill
When init destroys a child server with an open session, the client must
be updated as it will otherwise store a pointer to a no-more existing
service object which will be dereferenced when the child client is
destroyed.

051e84c4b4 Move server API concept to base framework
This commit introduces the new `Component` interface in the form of the
headers base/component.h and base/entrypoint.h. The os/server.h API
has become merely a compatibilty wrapper and will eventually be removed.
The same holds true for os/signal_rpc_dispatcher.h. The mechanism has
moved to base/signal.h and is now called 'Signal_handler'.

Since the patch shuffles headers around, please do a 'make clean' in the
build directory.

705ac74498 CLI monitor: remove unused GDB command
This patch removes the support for executing subsystems of CLI monitor
within the GDB monitor. There are multiple reasons: First, the feature
remained unused for multiple years. Second, it relied on the base/elf.h
header to determine whether the started binary is dynamically or
statically linked. This header, however, is going to be removed from the
Genode API. Third, the feature will eventually break with the upcoming
changes of how components are bootstrapped. Finally, there is the plan
to turn CLI monitor into a sole front end of a dynamically configurable
init component. Once we pursue this plan, we'd need to reconsider the
GDB support anyway.

47b5ba3a89 linux/audio: use Server framework
In addition to now using the framework the playback is triggered by a
timer. For now it is a periodic timer that triggers every 11 ms which
is roughly the current Audio:out period (*).

The driver now also behaves like the other BSD Audio_out driver, i.e,
it always advances the play pointer. That is vital for the Audio_out
stack above the driver to work properly (e.g. the mixer).

(*) It stands to reason if it would be better to use the async ALSA
    timer interface instead of using the Timer session.

c10ad4ff01 ps2_drv: back down after unsucessful AUX access
The driver might end up in an endless loop on systems that do not
contain an i8042 controller when probing the AUX interface. This
leads to busy looping and in the end to not annoucing the Input
service. Components that wait for the announcement of the service
will therefore hang as well.

Normally a service gets announced only if it is usable but in this
case this is inconvient because it renders all scenarios that use
the input_merger non working on x86 systems that only provide USB
input and do not have PS/2 at all.

Ideally, the PS/2 driver should only be started if the system needs it.
That is currently not feasible and for the time being we post-pone the
inevitable and back down after several unsucessful attempts to read
from the AUX interface while initializing the driver.

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.

48e7d29686 sd_card & imx53: flush ADMA2 writes via DSB
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.

bd7fe4160d sd_card & imx53: fix initialization problem on QSB
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.

d8e91908a2 sd_card & imx53: install IRQ signal handler
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.

50dd0dda38 Notify report-rom client on signal-handler registration
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.

e4678a4dc1 decorator: do not defer stacking changes
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.
