ed0d76552b Relax timing requirements in lazy timer test
The lazy-timer test depends on the faster-timer handler to be executed
before the fast timeout occurs, which was pretty hard to achieve on Qemu
and a busy host machine. Therefore, I increased the fast-to-faster
timeout ratio from 50/25 ms to 200/25 ms and set the test runtime to
4000 ms.

181c78d482 timeout: use uint64_t for all plain time values
This enforces the use of unsigned 64-bit values for time in the duration type,
the timeout framework, the timer session, the userland timer-drivers, and the
alarm framework on all platforms. The commit also adapts the code that uses
these tools accross all basic repositories (base, base-*, os. gems, libports,
ports, dde_*) to use unsigned 64-bit values for time as well as far as this
does not imply profound modifications.

aa66b5d62f base: remove dependency from deprecated APIs
This patch adjusts the implementation of the base library and core such
that the code no longer relies on deprecated APIs except for very few
cases, mainly to keep those deprecated APIs in tact for now.

The most prominent changes are:

- Removing the use of base/printf.h

- Removing of the log backend for printf. The 'Console' with the
  format-string parser is still there along with 'snprintf.h' because
  the latter is still used at a few places, most prominently the
  'Connection' classes.

- Removing the notion of a RAM session, which does not exist in
  Genode anymore. Still the types were preserved (by typedefs to
  PD session) to keep up compatibility. But this transition should
  come to an end now.

- Slight rennovation of core's tracing service, e.g., the use of an
  Attached_dataspace as the Argument_buffer.

- Reducing the reliance on global accessors like deprecated_env() or
  core_env(). Still there is a longish way to go to eliminate all such
  calls. A useful pattern (or at least a stop-gap solution) is to
  pass the 'Env' to the individual compilation units via init functions.

- Avoiding the use of the old 'Child_policy::resolve_session_request'
  interface that returned a 'Service' instead of a 'Route'.

af146e7dcd Remove base/timed_semaphore.h from API
The former 'Genode::Timed_semaphore' mechanism is moved to the private
part of the two remaining users, namely dde_rump and the libc. Note
there are now two private copies of 'timed_semaphore.h'. This should be
regarded as an interim step until the use of this mechanism is removed
from both users.

This patch also cleans up the mechanism from legacy Genode API calls and
global side effects (alarm-thread singleton). The test/timed_semaphore
is now located at the libports repository as it now tests a mechanism of
the libc. The former timed_semaphore library is no more.

bf62d6b896 Move timer from os to base repository
Since the timer and timeout handling is part of the base library (the
dynamic linker), it belongs to the base repository.

Besides moving the timer and its related infrastructure (alarm, timeout
libs, tests) to the base repository, this patch also moves the timer
from the 'drivers' subdirectory directly to 'src' and disamibuates the
timer's build locations for the various kernels. Otherwise the different
timer implementations could interfere with each other when using one
build directory with multiple kernels.

Note that this patch changes the include paths for the former os/timer,
os/alarm.h, os/duration.h, and os/timed_semaphore.h to base/.

34480c9269 test-rm_fault: use ld.lib.so to test read-only mem
Due to the changing environment this test is executed (like depot_autopilot)
the binary test-rm_fault used to check ROM dataspace's read-only property
does not suit anymore. This commit changes the binary to ld.lib.so that is
normally still provided as a ROM dataspace.

c270e4fb30 base: exception safety during registry iteration
This patch fixes a problem in the non-const 'for_each' method of the
'Registry' data structure. If an exception was thrown from within the
functor of the 'for_each' operation, the not yet processed items of the
registry were dropped from the registry, which is not expected.

1261c18ce9 ada: runtime and library support
The Ada runtime can now be set with the ADA_RTS variable. The ada
library builds a (currently) minimal runtime from the gcc sources that
come with Genode (to stay consistent with the used compiler) and sets
the runtime path accordingly. It is build as a shared library ada.lib.so
which needs to be added to the build files.

I split the existing Ada test into program and library, and moved it
to libports as it depends on the runtime library residing in this
repository too.

eba9c15746 Follow practices suggested by "Effective C++"
The patch adjust the code of the base, base-<kernel>, and os repository.
To adapt existing components to fix violations of the best practices
suggested by "Effective C++" as reported by the -Weffc++ compiler
argument. The changes follow the patterns outlined below:

* A class with virtual functions can no longer publicly inherit base
  classed without a vtable. The inherited object may either be moved
  to a member variable, or inherited privately. The latter would be
  used for classes that inherit 'List::Element' or 'Avl_node'. In order
  to enable the 'List' and 'Avl_tree' to access the meta data, the
  'List' must become a friend.

* Instead of adding a virtual destructor to abstract base classes,
  we inherit the new 'Interface' class, which contains a virtual
  destructor. This way, single-line abstract base classes can stay
  as compact as they are now. The 'Interface' utility resides in
  base/include/util/interface.h.

* With the new warnings enabled, all member variables must be explicitly
  initialized. Basic types may be initialized with '='. All other types
  are initialized with braces '{ ... }' or as class initializers. If
  basic types and non-basic types appear in a row, it is nice to only
  use the brace syntax (also for basic types) and align the braces.

* If a class contains pointers as members, it must now also provide a
  copy constructor and assignment operator. In the most cases, one
  would make them private, effectively disallowing the objects to be
  copied. Unfortunately, this warning cannot be fixed be inheriting
  our existing 'Noncopyable' class (the compiler fails to detect that
  the inheriting class cannot be copied and still gives the error).
  For now, we have to manually add declarations for both the copy
  constructor and assignment operator as private class members. Those
  declarations should be prepended with a comment like this:

        /*
         * Noncopyable
         */
        Thread(Thread const &);
        Thread &operator = (Thread const &);

  In the future, we should revisit these places and try to replace
  the pointers with references. In the presence of at least one
  reference member, the compiler would no longer implicitly generate
  a copy constructor. So we could remove the manual declaration.

As noted above the former enum for the local-attachment address we

runtime on 64-bit Linux. The local_attach_addr is now configurable in
the run script and the memory maps heuristics were removed.

4d442bca30 Streamline exception types
This patch reduces the number of exception types by facilitating
globally defined exceptions for common usage patterns shared by most
services. In particular, RPC functions that demand a session-resource
upgrade not longer reflect this condition via a session-specific
exception but via the 'Out_of_ram' or 'Out_of_caps' types.

Furthermore, the 'Parent::Service_denied', 'Parent::Unavailable',
'Root::Invalid_args', 'Root::Unavailable', 'Service::Invalid_args',
'Service::Unavailable', and 'Local_service::Factory::Denied' types have
been replaced by the single 'Service_denied' exception type defined in
'session/session.h'.

This consolidation eases the error handling (there are fewer exceptions
to handle), alleviates the need to convert exceptions along the
session-creation call chain, and avoids possible aliasing problems
(catching the wrong type with the same name but living in a different
scope).
