2cde1d36c1 base: changes for GDB monitor
- add a new function 'binary_ready_hook_for_gdb()' in ldso. GDB can set a
  breakpoint at this function to know when ldso has loaded the binary
  into memory.
- get the thread state from the NOVA kernel immediately on 'pause()'

a99989af40 Separation of thread operations from CPU session
This patch moves the thread operations from the 'Cpu_session'
to the 'Cpu_thread' interface.

A noteworthy semantic change is the meaning of the former
'exception_handler' function, which used to define both, the default
exception handler or a thread-specific signal handler. Now, the
'Cpu_session::exception_sigh' function defines the CPU-session-wide
default handler whereas the 'Cpu_thread::exception_sigh' function
defines the thread-specific one.

To retain the ability to create 'Child' objects without invoking a
capability, the child's initial thread must be created outside the
'Child::Process'. It is now represented by the 'Child::Initial_thread',
which is passed as argument to the 'Child' constructor.

a7b3072cc2 Pass Env & as first argument to connection objects
This patch supplements each existing connection type with an new
constructor that is meant to replace the original one. The new
one takes a reference to the component's environment as argument and
thereby does not rely on the presence of the globally accessible
'env()' interface.

The original constructors are marked as deprecated. Once we have
completely abolished the use of the global 'env()', we will remove them.

cb232891bf Fix noux.run on base-linux
The recent move of the initial three region maps into the PD session
breaks the noux.run test on Linux because the address spaces are locally
managed on this platform but the generic code of Noux still tries to
execute the regular procedure of creating the virtualized PD session for
a new Noux process. This patch handles a corner case that occurs on
Linux but no other platform. It enables the successful creation of the
virtualized PD session so that the test runs to completion. Still noux
on Linux remains to be limited to non-forking programs.

fd401bdf53 Thread API cleanup
This patch cleans up the thread API and comes with the following
noteworthy changes:

- Introduced Cpu_session::Weight type that replaces a formerly used
  plain integer value to prevent the accidental mix-up of
  arguments.
- The enum definition of Cpu_session::DEFAULT_WEIGHT moved to
  Cpu_session::Weight::DEFAULT_WEIGHT
- New Thread constructor that takes a 'Env &' as first argument.
  The original constructors are now marked as deprecated. For the
  common use case where the default 'Weight' and 'Affinity' are
  used, a shortcut is provided. In the long term, those two
  constructors should be the only ones to remain.
- The former 'Thread<>' class template has been renamed to
  'Thread_deprecated'.
- The former 'Thread_base' class is now called 'Thread'.
- The new 'name()' accessor returns the thread's name as 'Name'
  object as centrally defined via 'Cpu_session::Name'. It is meant to
  replace the old-fashioned 'name' method that takes a buffer and size
  as arguments.
- Adaptation of the thread test to the new API

7274ca997d Remove Genode::Process from API
This patch makes the former 'Process' class private to the 'Child'
class and changes the constructor of the 'Child' in a way that
principally enables the implementation of single-threaded runtime
environments that virtualize the CPU, PD, and RAM services. The
new interfaces has become free from side effects. I.e., instead
of implicitly using Genode::env()->rm_session(), it takes the reference
to the local region map as argument. Also, the handling of the dynamic
linker via global variables is gone. Now, the linker binary must be
provided as constructor argument.

b49e588c1c Assign threads to PD at its creation time
This patch replaces the former 'Pd_session::bind_thread' function by a
PD-capability argument of the 'Cpu_session::create_thread' function, and
removes the ancient thread-start protocol via 'Rm_session::add_client' and
'Cpu_session::set_pager'. Threads are now bound to PDs at their creation
time and implicitly paged according to the address space of the PD.

Note the API change:

This patch changes the signature of the 'Child' and 'Process' constructors.
There is a new 'address_space' argument, which represents the region map
representing the child's address space. It is supplied separately to the
PD session capability (which principally can be invoked to obtain the
PD's address space) to allow the population of the address space
without relying on an 'Pd_session::address_space' RPC call.
Furthermore, a new (optional) env_pd argument allows the explicit
overriding of the PD capability handed out to the child as part of its
environment. It can be used to intercept the interaction of the child
with its PD session at core. This is used by Noux.

511acad507 Consolidate RM service into PD session
This patch integrates three region maps into each PD session to
reduce the session overhead and to simplify the PD creation procedure.
Please refer to the issue cited below for an elaborative discussion.

Note the API change:

With this patch, the semantics of core's RM service have changed. Now,
the service is merely a tool for creating and destroying managed
dataspaces, which are rarely needed. Regular components no longer need a
RM session. For this reason, the corresponding argument for the
'Process' and 'Child' constructors has been removed.

The former interface of the 'Rm_session' is not named 'Region_map'. As a
minor refinement, the 'Fault_type' enum values are now part of the
'Region_map::State' struct.

0c299c5e08 base: separate native CPU from CPU session
This patch unifies the CPU session interface across all platforms. The
former differences are moved to respective "native-CPU" interfaces.

NOVA is not covered by the patch and still relies on a custom version of
the core-internal 'cpu_session_component.h'. However, this will soon be
removed once the ongoing rework of pause/single-step on NOVA is
completed.

051e84c4b4 Move server API concept to base framework
This commit introduces the new `Component` interface in the form of the
headers base/component.h and base/entrypoint.h. The os/server.h API
has become merely a compatibilty wrapper and will eventually be removed.
The same holds true for os/signal_rpc_dispatcher.h. The mechanism has
moved to base/signal.h and is now called 'Signal_handler'.

Since the patch shuffles headers around, please do a 'make clean' in the
build directory.

62b1c55399 Integrate CAP session into PD session
This patch integrates the functionality of the former CAP session into
the PD session and unifies the approch of supplementing the generic PD
session with kernel-specific functionality. The latter is achieved by
the new 'Native_pd' interface. The kernel-specific interface can be
obtained via the Pd_session::native_pd accessor function. The
kernel-specific interfaces are named Nova_native_pd, Foc_native_pd, and
Linux_native_pd.

The latter change allowed for to deduplication of the
pd_session_component code among the various base platforms.

To retain API compatibility, we keep the 'Cap_session' and
'Cap_connection' around. But those classes have become mere wrappers
around the PD session interface.

040cd95580 noux: fix context-area re-initialization in fork
With commit e74b53d5dd the fork semantic in noux
changed slightly, and broke platforms like hw & sel4, where the UTCB is mapped
directly into the thread's context area. The change moved the re-initialization
to a point where the new noux process' thread stack-pointer was already switched
back to the context area. But to re-initialize the context area RPC calls must
be done, and the UTCB must be used therefore. On the other side the UTCB is
found implicitly by the stack-pointer, whereby a stack-pointer located in the
context-area refers to a UTCB that is expected to reside in the context-area
as well. But the UTCB gets overlayed inside the context area by the
context-area's re-initialization - we've come round in a circle.

This commit rolls back the move of the re-initialization routine. To preserve
the intention of the original commit, the context-area location is stored in
a static variable, so that the Native_config API is not needed anymore.
