4736488d99 core: change order of _export_ds and _clear_ds
On seL4, we need to convert untyped memory to page frames before being
able to use it as normal memory. There already exists the hook function
'_export_ds' that is principally suitable for such tasks. It is
currently solely used on Linux where we have to create a file for each
dataspace. To make the hook useful also for seL4, we need to call
_export_ds prior _clear_ds. Otherwise, we would try to clear memory that
is still untyped.

7c133add52 hw: acknowledge IRQs via Kernel::ack_irq
In the past, when the user blocked for an IRQ signal, the last signal was
acknowledged automatically thereby unmasking the IRQ. Now, the signal session
got a dedicated RPC for acknowledging IRQs and the HW back-end of that RPC
acknowledged the IRQ signal too. This led to the situation that IRQs were
unmasked twice. However, drivers expect an interrupt to be unmasked only on
the Irq_session::ack_irq and thus IRQ unmasking was moved from
Kernel::ack_signal to a dedicated kernel call.

c9272937e7 CPU session: apply quota via relative weightings
Physical CPU quota was previously given to a thread on construction only
by directly specifying a percentage of the quota of the according CPU
session. Now, a new thread is given a weighting that can be any value.
The physical counter-value of such a weighting depends on the weightings
of the other threads at the CPU session. Thus, the physical quota of all
threads of a CPU session must be updated when a weighting is added or
removed. This is each time the session creates or destroys a thread.

This commit also adapts the "cpu_quota" test in base-hw accordingly.

85599c072f os: use async IRQ and server lib in drivers
Use the new asynchronous IRQ interface in the mostly used drivers, e.g.:

* ahci_drv: x86/exynos5
* gpio_drv: imx53/omap4
* input_drv: imx53/dummy
* ps2_drv: x86/pl050
* timer_drv

Now, the Irq_session is requested from Gpio::Session:

From now on we use an asynchronous IRQ interface. To prevent triggering
another GPIO IRQ while currently handling the former one, IRQs must
now by acknowledged explicitly. While here, we also changed the GPIO
session interface regarding IRQ management. The generic GPIO component
now wraps the Irq_session managed by the backend instead of using the
GPIO backend methods directly. A client using the GPIO session may
request the Irq_session_capability by calling
'Gpio::Session::irq_session()' and can use this capability when using
a local Irq_session_client.

9606abc146 dde_ipxe: remove dde_kit
A long long time ago, in a galaxy^W^W^W we used DDE kit to ease the
porting of purely C based drivers. By now it became clear, that we
do not gain that much by following this approach. DDE kit contains
much generic functionality, which is not used or rather not needed
by most ported drivers. Hence, we implement a slim C wrapper on top
of Genode's C++ APIs, that is especially tailored to the driver.

In addition to removing the dependency on DDE kit, the iPXE driver
now uses the server framework and the newly introduced signal based
IRQ handling.

0fd53c7fe4 Extract numeric string arguments with the correct signedness
There are lots of places where a numeric argument of an argument string
gets extraced as signed long value and then assigned to an unsigned long
variable. If the value in the string was negative, it would not be
detected as invalid (and replaced by the default value), but become a
positive bogus value.

With this patch, numeric values which are supposed to be unsigned get
extracted with the 'ulong_value()' function, which returns the default
value for negative numbers.

91e0a5d5dd SD-card driver for the Raspberry Pi
The driver operates in PIO mode only. Depending on the block size (512
bytes versus 128 KiB), it has a troughput of 2 MiB/sec - 10 MiB/sec for
reading and 173 KiB/sec - 8 MiB/sec for writing.
