dd47129bef nic session: link-state change handling
A Nic::Session client can install a signal handler that is used to
propagate changes of the link-state by calling 'link_state_sigh()'.
The actual link state is queried via 'link_state()'.

The nic-driver interface now provides a Driver_notification callback,
which is used to forward link-state changes from the driver to the
Nic::Session_component.

The following drivers now provide real link state: dde_ipxe, nic_bridge,
and usb_drv. Currently, OpenVPN, Linux nic_drv, and lan9118 do not
support link state and always report link up.

9d5b119186 wifi_drv: add dummy member to empty structs
The size of empty structs differs in C (0 byte) and C++ (1 byte), which
leads to different offsets in compound structures. This fixes the driver
on 32Bit platforms.

7e69013e0c wifi_drv: store timeout also in timer_list.expires
The wireless stack calls timer_before(foo, timer.expires) and up to now
it was always 0. Let's be save and set this field when scheduling the
timer, although it worked fine so far.

c46e3db4d5 wifi_drv: silence 'Slab too large' error
We will always see this error message when the driver is started. It
is expected and not an actual error. When the driver is running it will
not allocate larger chunks than the Slab provides. Therefore, we can
safely ignore this message.

85031f1c1a wifi: report wlan networks
The wifi_drv now provides two reports. The first one contains all
accesspoints that were found while scanning the supported frequencies.
The second one reports the state of the driver, i.e., if it is
conntected to an accesspoint or not. In addition to that, the driver
now gets its configuration via a ROM session.

More detailed information are available in 'repos/dde_linux/README'.

6d2c697da1 lxip: Fix timeout handling for 'schedule_timeout'
Up until now 'schedule_timeout' did only wait for the next signal to occur.
However, we might run into situations where there won't occur signals for longer
periods of time. Therefore, we took care of the respective timeout handling.

This commit also adds Genode's tracing support

4c7a5bb388 wifi_drv: call schedule() in sleep functions
The jiffies are only updated on each round of scheduling the runnable
tasks. We have to schedule the current task that executes the sleep
call to update the jiffies count and thereby preventing the task from
entering an endless loop when using a statement like
'while (!time_after(jiffies, now + timeout)) { msleep(1); }'.

9ed935ff2a wifi_drv: look for PCI_CLASS_NETWORK_OTHER only
Instead of probing all device on the PCI bus just look for devices
matching PCI_CLASS_NETWORK_OTHER. This fixes issues with other devices
on the PCI bus, e.g. the GPU, when access their extended config space.

786fe805da base: introduce caching attributes (fix #1184)
On ARM it's relevant to not only distinguish between ordinary cached memory
and write-combined one, but also having non-cached memory too. To insert the
appropriated page table entries e.g.: in the base-hw kernel, we need to preserve
the information about the kind of memory from allocation until the pager
resolves a page fault. Therefore, this commit introduces a new Cache_attribute
type, and replaces the write_combined boolean with the new type where necessary.

0ed68a56b7 Use signals for delivering input events
This patch changes both the Input::Session interface and the skeleton
for the server-side implementation of this interface
('input/component.h').

The Input::Session interface offers a new 'sigh' function, which can be
called be the client to register a signal handler. The signal handler
gets notified on the arrival of new input. This alleviates the need to
poll for input events at the client side.

The server-side skeleton for implementing input services underwent a
redesign to make it more modular and robust. I.e., there are no
global functions needed at the server side and the event-queue
enable/disable mechanism is implemented at a central place (in the root
component) rather than inside each driver.

24f97f9593 usb_drv: Check SCSI command queue state
In case the storage-entry point dispatches more then one packet, wait for the
previous command to finish before setting a new request. This has to be done
because the 'queuecommand' does actually *not* queue things, but can only handle
one request at the time.
