957fe694c5 Noux: provide separate configuration for child processes
Instead of passing on the Noux 'config' ROM dataspace to child processes,
provide a separate configuration for each Noux child, which is either
'<config/>' or '<config ld_verbose="yes"/>', depending on the
configuration of this attribute for the Noux process. This is also a
workaround to prevent multiple insertion of the same 'config' ROM
dataspace capability into the dataspace registry.

1208d14681 hw: use kernel timer for timer driver
* Adds public timeout syscalls to kernel API
  * Kernel::timeout installs a timeout and binds a signal context to it that
    shall trigger once the timeout expired
  * With Kernel::timeout_max_us, one can get the maximum installable timeout
  * Kernel::timeout_age_us returns the time that has passed since the
    calling threads last timeout installation

* Removes all device specific back-ends for the base-hw timer driver and
  implements a generic back-end taht uses the kernel timeout API

* Adds assertions about the kernel timer frequency that originate from the
  requirements of the the kernel timeout API and adjusts all timers
  accordingly by using the their internal dividers

* Introduces the Kernel::Clock class. As member of each Kernel::Cpu object
  it combines the management of the timer of the CPU with a timeout scheduler.
  Not only the timeout API uses the timeout scheduler but also the CPUs job
  scheduler for installing scheduling timeouts.

* Introduces the Kernel::time_t type for timer tic values and values inherited
  from timer tics (like microseconds).

722fd85bc1 hw: higher names for core restricted syscalls
To avoid the need for adapting the names of the core restricted syscalls
each time we add a public syscall (restricted names must always be
greater than public names), let restricted syscall names simply start at
100 (we should never have more than 100 public syscalls).

0106045bad lx_kit: add modular lx_emul backend
The modular lx_kit seperates the required back end functionality of the
Linux emulation environment from the front end. Thereby each driver can
reuse specific parts or supply more suitable implementations by itself.
It is used to reduce the amount of redundant code in each driver.

The lx_kit is split into several layers whose structure is as follows:

The first layer in _repos/dde_linux/src/include/lx_emul_ contains those
header files that provide the structural definitions and function
declarations of the Linux API, e.g. _errno.h_ provides all error code
values. The second layer in _repos/dde_linux/src/include/lx_emul/impl_
contains the implementation of selected functions, e.g. _slab.h_
provides the implementation of 'kmalloc()'. The lx_kit back end API is
the third layer and provides the _Lx::Malloc_ interface
(_repos/dde_linux/src/include/lx_kit/malloc.h_) which is used to
implement 'kmalloc()'. There are several generic implementations of the
lx_kit interfaces that can be used by a driver.

A driver typically includes a 'lx_emul/impl/xyz.h' header once
directly in its lx_emul compilation unit. The lx_kit interface files
are only included in those compilation units that use or implement the
interface. If a driver wants to use a generic implementation it must
add the source file to its source file list. The generic
implementations are located in _repos/dde_linux/src/lx_kit/_.

The modular lx_kit still depends on the private _lx_emul.h_ header file
that is tailored to each driver. Since the lx_kit already contains much
of the declarations and definitions that were originally placed in
these private header files, those files can now ommit a large amount
of code.

47990f37d7 dde_bsd: update audio driver to OpenBSD 5.9
In addition to updating the contrib sources the driver now uses the
new Component API and will report the internal mixer state.

Reporting of the mixer state is enabled by adding the 'report_mixer'
attribute to the drivers configuration and setting its value to 'yes'.

The following snippets illustrates the format of the report:

!<mixer_state>
!  <mixer field="inputs.beep" value="108"/>
!  <mixer field="outputs.hp_sense" value="plugged"/>
!  <mixer field="outputs.master" value="128,128"/>
!  <mixer field="outputs.mic_sense" value="unplugged"/>
!  <mixer field="outputs.spkr_muters" value="hp,mic"/>
!</mixer_state>

The mixer state may expose other mixer fields as well, depending on the
used sound card. The naming scheme of the attributes intentionally
matches the naming scheme of OpenBSD's mixerctl(1) program.

Each 'mixer' node can be used to configure the audio driver by using it
in its configuration, e.g.:

!<config report_mixer="yes">
!  <mixer field="outputs.master" value="255,255"/>
!</config>

This configuration will set the output volume to the highest possible
value. Although it is now also possible to update the configuration
at run-time it should not be done while the driver is currently playing
or recording because it may provoke the generation of artefacts.

111d74744d hw_x86_64: remove aligment attribute from FPU context
We do not ensure that the Fpu::Context is 16-byte aligned and,
therefore, should not tell the compiler that we did. Otherwise, the GCC
may optimize operations regarding the addresses of members as it did for

  if ((addr_t)_fxsave_area & 0xf) ...

With the declared 16-byte alignment the condition will never become
true.

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.
