Add a Platform::setup_irq_mode function which enables the IRQ session to
update the trigger mode and polarity of the associated IRQ according to
the session parameters. On ARM this function is a nop.
This change enables the x86_64 platform to support devices which use
arbitrary trigger modes and polarity settings, e.g. AHCI on QEMU and
real hardware.
Fixes#1528.
Because of helping, it is possible that a core thread that wants to
destroy another thread at the kernel is using the scheduling context of
the thread that shall be destroyed at this point in time. When building
without GENODE_RELEASE defined, this always triggers an assertion in the
kernel. But when building with GENODE_RELEASE defined, this might silently
lead to kernel-memory corruption. This commit eliminates the latter case.
Should be reverted as soon as the scheduler is able to remove its head.

Placement new can be misleading, as we already overload the new operator
to construct objects via pointers to allocators. To prohibit any problems here,
and to use one consistent approach, we can explicitely construct the object
with the already available 'construct_at' template function.

* Introduce a hw specific Address_space interface for protection
domains, which combines all memory-virtualization related functionality
* Introduce a core-specific Platform_pd object that solves all the hen-egg
problems formerly distributed in kernel and core-platform code

Ref #1443
For several basic sessions that core provides default ram quota values
exist in the form of enum values. They are used e.g. by init to deduce
session costs. Unfortunately they were not used when actually establishing
the session, which lead to inconsistencies.
Ref #1443
This patch installs the parent endpoint selector and the PD's CNode into
a PD at its creation time. Furthermore, it initializes the IPC buffer
for the main thread of the new component.
This allows us to see debug messages printed at the eary initialization
of init (before init is able to obtain the regular LOG session). This
will be reverted as soon as the initialziation of the non-core base
environment works.
