c79687f5f4 gpio: introduce Pin and '_with_gpio'
- make GPIO server more robust on imx by not throwing exceptions for
  unknown pins, use '_with_gpio' instead
- use 'Gpio::Pin' data type instead of POD 'unsigned'

5d808cdc01 platform_drv: extend MSI-X supports
The patch handles the case, that the memory for the MSI-X table is part
of one of the Pci::Resource Memory BARs, which got allocated beforehand already.

With this commit, the platform driver will not fall back to use legacy IRQs or MSI, whereby MSI-X is available actually. Additionally, this patch avoids a lot of red
messages about non available IO-MEM printed by the roottask.

04821b1abc nitpicker: apply focus change w/o input events
This patch fixes the corner case where the keyboard focus is defined
independently from user interactivity, e.g., the activation of a
screensaver or lock screen.

In this case, nitpicker would update its internal focus state not before
the next input event is handled. Should this input event be a press
event, this event would wrongly be delivered to the prior focused
session. Another problematic situation is the initial state before the
very first input event occurs. Since the focus remains undefined until
the first input event is handled, an initial key press event would not
be delivered.

This is a regression caused be the transition to the event-session
interface and the removal of the nitpicker's periodic way of operation.
The patch fixes the problem by applying pending focus changes not only
at the input processing but also on the code path that responds to focus
changes (e.g., focus-rom update).

2eb8c5e21a net: move ascii_to() into Net namespace
The combination of Net::Mac_address and
Genode::ascii_to(Net::Mac_address) required shaky quirks in several
places because GCC is not able to resolve the ascii_to overload if
base/xml_node.h was included to early. The current solution moves the
several ascii_to overloads "closer" to the Net types by putting them
into the Net namespace, where GCC reliably picks them up.

Hence, co-locating the ascii_to() utility with the overload type in the
same scope/namespace is good practice.

This patch removes the now obsolete <nic/xml_node.h> header file.

7de2b040f8 vfs: deliver ACKs after config change
This is needed to enable VFS plugins to notify VFS clients about file
changes that depend on the plugin configuration, E.g., whenever the vfs_ttf
plugin responds to a font-size change, it generates a watch notification
for the glyphs file. Since the change is independent from I/O, we need
to manually call 'handle_io_progress'.

328a4fa644 nitpicker: update hovering on view-stack changes
With the change of nitpicker to the event session interface, the
formerly periodic hovering updates moved to the - now sporadic - input
processing. This has the unfortunate side effect that hovering changes
caused by non-user-input, in particular view-stack changes issued by the
GUI clients that change the view under the current pointer position,
would no longer be reported immediately but only after receiving the
next incoming input event.

This patch reworks the hover handling such that potential hovering
changes due to view-stack operations are evaluated immediately by
those operations, covering the update of the hover report and the
generation of artificial enter/motion events.

17a6318ad6 vfs: process all acks in each iteration
This patch solves a corner case where one long-active job (e.g.,
read-ready request) stays at the beginning of the '_active_jobs' queue
without an ack. In this case, the '_try_acknowledge_jobs' method would
wrongly stop processing the subsequent acknowledgements. In practice,
this can lead to a delayed sending of acknowledgements until new I/O or
client requests occur. In particular, Vim in Sculpt's inspect window
sometimes did not immediately respond to key presses during tab
completion. Here, the read-ready request of the terminal prevented the
acknowledgement for read of directory entry from being delivered until
the next key was pressed.

5f5ad41ad3 hw: unify irq enumeration for Raspberri Pi
By now, the enumeration of peripheral interrupts on Raspberry Pi 1 was
different in between base-hw kernel and Fiasco.OC. Therefore, hacks were
needed in every driver to request the correct interrupt number dependent
on the kernel. Before reproducing the same in the platform driver for rpi,
we can more easily use the same enumeration with base-hw.

06edc0d52b base: extend PD session with managing_system call
Introduce the managing_system privilege for components like the
platform_driver to allow it to call system management functionality
that is reserved by kernel or special firmware, e.g., ARM Trusted Firmware.

The former RAM resource configuration attribute `constrain_phys`,
which enabled to constrain the region of physical RAM to be used,
gets replaced by the new, broader managing_system configuration
attribute of a `start` node. It gets enforced by the sandbox library.

c7d9b2ca92 nitpicker: fix mode change for requested fb
This is a follow-up commit to "nitpicker: make framebuffer and input
optional". It restores the dynamic mode-change support when using
'request_framebuffer="yes"' as needed in scenarios where multiple
nitpicker instances are used in a cascaded way. E.g., Sculpt's
Leitzentrale. The previous version missed to reconstruct the
'_fb_screen' on mode changes.

2e22498e5a nitpicker: no framebuffer and input by default
This patch prevents nitpicker from requesting a framebuffer and input
session by default because the regular use of nitpicker relies on the
capture-session and event-session interfaces by now.

For supporting the nested use of nitpicker via the gui_fb component, it
is still possible to enable the traditional behavior by explicitely
setting the 'request_input' and 'request_framebuffer' config attributes
to "yes".

9662d89cfb Replace input filter with event filter
This commit applies the transition from the "Input" session to the "Event"
session to the event-filtering mechansim. The functionality of the
input_filter is now provided by the event_filter. The event filter
requests only one "Event" session as destination for the filter result,
which is usually routed to the nitpicker GUI server. It provides an
"Event" service to which any number of event sources can connect.

The configuration of the filter chain remains almost the same. Only the
declaration of the <input> nodes is no longer needed. Instead, the
configuration must specify <policy> nodes, which define the mapping of
"Event" clients (event sources) to the inputs used in the filter chain.

The patch adjusts all uses of the nitpicker GUI server accordingly such
that the event filter reports events to nitpicker's event service
instead of having nitpicker request an "Input" session. This dissolves
the dependency of nitpicker from input drivers.

c502e1d095 input_filter: prepare for refactorization
This patch brings the input filter into a shape that is easier to
re-mold into an event filter, reversing the client/server roles of
the component.

* The 'Sink &destination' is no longer passed as constructor argument
  to the individual filters but passed as argument to the 'generate'
  method. This way, the final destination does not need to exist at
  the construction time of the filter chain but can be created on
  the fly (clearing the way for using 'Event::Client::with_batch').

* A new 'Source::Filter' interface with the 'apply' method aids the
  cascading of filters during 'generate'. The modules now implement
  the 'Source::Filter::filter_event' interface instead of the
  'Source::Sink::submit_event' interface.

* Since the 'Sink &destination' is no longer a member of the filter
  modules, character-repeat events can no longer be emitted in an
  ad-hoc way. Instead, the character-repeat mechanism now invokes
  a new 'Trigger::trigger_generate' hook that prompts the execution
  of the regular 'generate' mechanism by the main program.

This patch is supposed to leave the semantics of the input filter
unchanged (validated by the input_filter.run script).
