bd52e49698 os: remove startup lib from dynamic programs
All the pre- and post-processing of the startup lib around the main
function of a dynamic program is now done by LDSO. Hence LDSO directly
calls the main function of the program.

f447fbe1a5 base: Do not link base libs against shared libs
Base libraries are already contained within ldso.lib.so. Remove unnecessary
filtering from 'dep_lib.mk', make ldso depend on base libs.

0b64328944 base: setup thread object for main thread in CRT0
For a main thread a thread object is created by the CRT0 before _main gets
called so that _main can already run in a generic environment that, e.g.,
catches stack overflows as a page-fault instead of corrupting the BSS.
Additionally dynamic programs have only one CRT0 - the one of the LDSO -
which does the initialization for both LDSO and program.

c6ed7f13bf os: initial preparation for 64Bit AHCI support
The AHCI driver seems to work on x86_64, though it should be treated
carefully because for now all adresses involved are <= 32Bit.

8243329ad4 os: Move Genode::Config into 'config' library
Originally, the convenience utility for accessing a process
configuration came in the form of a header file. But this causes
aliasing problems if multiple compilation units access the config while
the configuration gets dynamically updated. Moving the implementation of
the accessor to the singleton object into a library solves those
problems.

664d0036c8 Use cpu regulator in cli_monitor only on Arndale
This commit splits the Fiasco.OC-specific extension for the cli_monitor
into one for the Arndale platform, and one for all others. On Arndale
we add the cpu_frequency command beside the ones defined on all platforms.

4a9b1c6aab base-linux: add ARM support
This patch introduces a new platform 'linux_arm' for building and running
Genode/Linux on an ARM device.

Known limitations:

- libc 'setjmp()'/'longjmp()' doesn't currently save/restore floating
  point registers

e164671cd1 ahci_drv: basic support for exynos 5
This is a first version of the AHCI driver. It supports SATA HDDs
with UDMA-133 only, up to 6 Gbps and native command queueing.
The more blocks one transfers with one command, the higher is the
chance that the driver produces a fatal handshake error. Nevertheless
the driver is stable with one block per ATA command. Although NCQ is
used the driver doesn't queue multiple commands simultanously.

The driver was tested with a western digital HDD "WDC WD2500BEVS-08VAT1
13.01A13" (250 GB) with hw_arndale (run/ahci) and foc_arndale
(run/ahci, run/l4linux: dd). SSDs were not tested.

fae63f4fa9 Merge base libraries into a single library
This patch simplifies the way of how Genode's base libraries are
organized. Originally, the base API was implemented in the form of many
small libraries such as 'thread', 'env', 'server', etc. Most of them
used to consist of only a small number of files. Because those libraries
are incorporated in any build, the checking of their inter-dependencies
made the build process more verbose than desired. Also, the number of
libraries and their roles (core only, non-core only, shared by both core
and non-core) were not easy to capture.

Hereby, the base libraries have been reduced to the following few
libraries:

- startup.mk contains the startup code for normal Genode processes.
  On some platform, core is able to use the library as well.
- base-common.mk contains the parts of the base library that are
  identical by core and non-core processes.
- base.mk contains the complete base API implementation for non-core
  processes

Consequently, the 'LIBS' declaration in 'target.mk' files becomes
simpler as well. In the most simple case, only the 'base' library must
be mentioned.

20a5c86a22 timer: Build platform-specific parts as lib
By using the build system's library-selection mechanism instead of many
timer targets with different 'REQUIRES' declarations, this patch reduces
the noise of the build system. For all platforms, the target at
'os/src/drivers/timer' is built. The target, in turn, depends on a
'timer' library, which is platform-specific. The various library
description files are located under 'os/lib/mk/<platform>'. The common
bits are contained in 'os/lib/mk/timer.inc'.

af66043b79 New Input::Event::FOCUS, rename keycode to code
This patch introduces keyboard-focus events to the 'Input::Event' class
and changes the name 'Input::Event::keycode' to 'code'. The 'code'
represents the key code for PRESS/RELEASE events, and the focus state
for FOCUS events (0 - unfocused, 1 - focused).

Furthermore, nitpicker has been adapted to deliver FOCUS events to its
clients.

959df5d46b Generalize handling of PD-session arguments
On Linux, we want to attach additional attributes to processes, i.e.,
the chroot location, the designated UID, and GID. Instead of polluting
the generic code with such Linux-specific platform details, I introduced
the new 'Native_pd_args' type, which can be customized for each
platform. The platform-dependent policy of init is factored out in the
new 'pd_args' library.

The new 'base-linux/run/lx_pd_args.run' script can be used to validate
the propagation of those attributes into core.

Note that this patch does not add the interpretation of the new UID and
PID attributes by core. This will be subject of a follow-up patch.

47ef3bb1cb NOVA: Fix ldso test for 64bit
The generic parent_cap.cc overwrote the beginning of the data segment with
to much. Reserved are solely 16 byte, for 64bit we use however 32byte.

Actually, the parent_cap copying is not required at all. The parent cap
selector is at a fixed define place, so that no exported symbols are required
for determination of the parent_cap.

Remove it.

de92956220 Read 'main()' function arguments from config file
This patch reads program arguments from the config file and makes them
available to the application via the 'argc' and 'argv' arguments of the
'main()' function. The configuration syntax looks like this:

<config>
	<arg value="...">
	<arg value="...">
        ...
</config>

The 'value' attribute of the first <arg> node becomes 'argv[0]' and so on.

48ac5143a2 Add spin lock to DDE Kit
Linux DDE used to implement Linux spin locks based on 'dde_kit_lock'.
This works fine if a spin lock is initialized only once and used
infinitely. But if spin locks are initialized on-the-fly at a high rate,
each initialization causes the allocation of a new 'dde_kit_lock'.
Because in contrast to normal locks, spinlocks cannot be explicitly
destroyed, the spin-lock emulating locks are never freed. To solve the
leakage of locks, there seems to be no other way than to support the
semantics as expected by the Linux drivers. Hence, this patch introduces
a DDE Kit API for spin locks.
