9dae5ee490 USB: Use real HID driver in dde_linux
Before, usb_drv included both the real HID driver and also Linux's early
boot USB driver (BP). The BP drivers have been removed now.

e8c063a8b4 base: release signal context from signal list
Remove signal context object from signal source component list (_signal_queue)
before destruction, otherwise we get a dangling pointer.

On native hardware for base-nova, the signal source thread triggered page
faults in the Signal_source_component::wait_for_signal() method when the signal
context got freed up in Signal_session_component::free_context but was still
enqueued in Signal_source_component::_signal_queue.

6fa57141ae Noux: delayed 'Child' object destruction
With this patch the destruction of Noux 'Child' objects gets delayed
further until the exit signal has been dispatched. This prevents the
self-destruction of the signal dispatcher, which is a member of the
'Child' object.

Fixes #603.

13d4108fea Unify 'Signal_dispatcher' interfaces
Several users of the signal API used custom convenience classes to
invoke signal-handling functions on the reception of incoming signals.
The 'Signal_dispatcher' pattern turned out to be particularly useful. To
avoid the duplication of this code across the code base, this patch
adds the interface to 'base/signal.h'.

Furthermore, the patch changes the 'Signal::num()' return type from int
to unsigned because negative numbers are meaningless here.

277af91376 Omit child-name prefix in <if-args> check
When matching the 'label' session argument using '<if-args>' in a
routing table, we can omit the child name prefix because it is always
the same for all sessions originating from the child anyway. Therefore,
this patch adds a special case for matching session labels. It makes the
expression of label-specific routing more intuitive.

c2d3543e62 base: replace obj_by_* by lookup_and_lock
Add functionality to lookup an object and lock it. Additional the case is
handled that a object may be already in-destruction and the lookup will deny
returning the object.

The object_pool generalize the lookup and lock functionality of the rpc_server
and serve as base for following up patches to fix dangling pointer issues.

ca37f26a01 base: add memory barrier before releasing lock
When releasing a lock we must take care that all state is written back to
memory and is not cached in registers. The volatile flag of the lock variable
only means to the compiler that this value must be written immediately.
Other values changed before may be kept by the compiler in registers, which we
don't want here.

Additionally the compiler is free to reorder the code in order to optimize.
That means the code we intend to be executed inside the critical section can
get be reordered and can be executed after we reset the lock variable in the
unlock implementation. The volatile statement of the lock variable doesn't
prevent reordering of instructions which are independent.

By adding a explicit memory barrier, we force the compiler to generate code
that writes back all the register content to memory/cache (and avoid a
bunch of hard to find bugs ...)

f9cb8a9ac3 dde_ipxe: Properly wrap iPXE interfaces to C++
As iPXE header files are not C++ compatible, the implementation missed
proper include directives. For example, alloc_memblock() had a wrong
signature, which was not detected. Now, C wrapper functions are
implemented using a local API to the C++ backend.

Related to #593.

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.
