d90b0464b8 Change order of thread-context members
Because 'stack' and 'stack_base' are related to each other, it makes
sense to locate both members close to each other.

ecdbdef8ee Loader: reflect faults to client
With this patch, the loader installs an optional client-provided fault
handler as default CPU exception handler and RM fault handler for all
CPU and RM sessions of the loaded subsystem. This way, loader clients
become able to respond to failures occuring within the subsystem.

The new feature is provided via the added 'Loader::fault_handler' RPC
function.

The 'run/failsafe' test covers two cases related to the loader, which
are faults produced by the immediate child of the loader and faults
produced by indirect children.

9f82764316 core: Introduce default CPU exception handler
The CPU session interfaces comes with the ability to install an
exception handler per thread. This patch enhances the feature with the
provision of a default signal handler that is used if no thread-specific
handler is installed. The default signal handler can be set by
specifying an invalid thread capability and a valid signal context
capability.

Furthermore, this patch relaxes the requirement of the order of the
calls of 'exception_handler' and 'set_pager'. Originally, the exception
handler could be installed not before setting a pager. Now, we remember
the installed exception handler in the 'Cpu_thread' and propagate to to
the platform thread at a later time.

693d657e6a base-linux: reflect SIGCHLD as Cpu_session signal
With this patch, core responds to SIGCHLD signals of terminating Genode
processes by reflecting these events as exceptions to the CPU session
interface. This way, Genode processes become able to respond to
terminating Genode child processes.

522a86e54a base-linux: use the Genode GCC's crt files
With this patch hybrid applications get linked with the Genode GCC's
'crtbegin.o' and 'crtend.o' files instead of the host GCC's versions
to avoid compatibility problems. This only affects the 'linux_x86'
platform, since on the 'lx_hybrid_x86' platform the Genode GCC is the
host GCC.

Fixes #550.

2283536b27 base: avoid deadlock in sliced_heap
It happens that ram_session and rm_session itself are invoking alloc
respectively free on the very same sliced heap inside core.

Lock only the sliced_heap list implementation and let the session locking to
the session implementation of rm_session and ram_session.

The ram_session and rm_session must take care to proper lock since inside
both implementations already the session handling thread and the service thread
are running parallel.

9cdf062ee6 base: catch exceptions in rm_session
For base-nova thread creation related exception can be thrown, since the
Pager_objects are threads. Catch the exception and re-throw the
expected/documented exception in rm_session.

This commit avoids that core dies with an unhandled exception if a thread
couldn't be created (e.g. because the limit has been reached).

f081733f4b Linux: remove 'some_mem' array in core
The Linux version of core used a part of the BSS to simulate access to
physical memory. All dataspaces would refer to a portion of 'some_mem'.
So every time when core would access the dataspace content, it would
access its local BSS. For all processes outside of core, dataspaces were
represented as files. This patch removes the distinction between core
and non-core processes. Now, core uses the same 'Rm_session_mmap'
implementation as regular processes. This way, the 'some_mem' could be
abandoned. We still use BSS variable for allocating core-local meta
data through.

bc24a21658 base-hw: embed kernel space into platform thread
Instead of allocating and freeing the space that is needed for the
kernel thread objects from core, wich is not convenient with the
quota system, platform thread now holds the space as array by
itself.

Unfortunately we cannot measure the space size by a static function
anymore, so kernel thread had to be moved from kernel.cc into its
own header. This way platform thread can use sizeof().
