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.

Related to #510.

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.

Fixes #184.

890a3ee868 Specialize blit library for ARM (fix #147).
Use multiple load store instructions for 32 byte chunks in ARM-specific
blit-function, analog to x86 variant. Make the blit-function of x86 a
generic one, and provide needed utility functions for ARM and generic code.
Please refer issue #147 for discussion.

319813a59b Merge spin-lock implementations
Separate spin-lock implementation from lock-implementation and put it into a
non-public header, so it can be re-used by the DDE kit's and Fiasco.OC's
capability-allocator spin lock. Fixes issue #123.

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.
