0ed45d92ff base: string length handling fix in Rpc_in_buffer
If a null-terminated string exactly of length MAX (0 byte included) is
provided, it will be handled as invalid because of wrong string size length
checks.

Commit fixes this.

Discovered during #1486 development.

6dd9d349fc pci: support shared irqs (x86)
Step to move shared irq handling out of core in the long run. So, use
irq_proxy implementation from base in os and implement shared irq handling
in platform driver of x86 (pci_drv).

98def2488a thread: move Thread_base::myself() to separate file
The thread library (thread.cc) in base-foc shared 95% of the code with
the generic implementation except myself(). Therefore, its
implementation is now separated from the other generic sources into
myself.cc, which allows base-foc to use a foc-specific primitive to
enable our base libraries in L4Linux.

50d6d2e922 okl4: fix return value if IPC failed
Otherwise RPC calls to dead/invalid destinations are rated as successful,
which leads to wrong execution paths later on. Triggered by bomb.run where
rm_session.attach() returned as successful with local address set to 0, which
causes un-handled page-faults later on.

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.

c850462f43 hw: replace kernel's object id allocators

b949489641 base: remove local capability from generic base
* Instead of using local capabilities within core's context area implementation
  for stack allocation/attachment, simply do both operations while stack gets
  attached, thereby getting rid of the local capabilities in generic code
* In base-hw the UTCB of core's main thread gets mapped directly instead of
  constructing a dataspace component out of it and hand over its local
  capability
* Remove local capability implementation from all platforms except Linux

63ebebcfa4 nitpicker: update the 'pointed session' more often
Currently, the 'pointed session' gets updated only when an input event
occurs, but an update is also needed in other situations, for example
when the view under the current mouse position was moved.

With this commit, the 'pointed session' gets updated whenever the
timer-triggered 'handle_input()' function is called.

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.
