ae1985bde2 l4lx: avoid creation of redundant thread for vcpus
This commit simplifies the creation of additional threads and VCPUs in L4linux.
By now, some Genode::Thread_base methods where overridden to use a Fiasco.OC
specific Cpu_session when creating threads.
Recent commit: 297538678e moved the actual creation
of the platform thread into the constructor of the generic Thread_base class.
Thereby the Vcpu class, which extended the Thread_base class, now unnecessarily
created two platform threads for each thread created via Vcpu. Nowadays, the
cpu_session capability is available via the Genode::env() environment. So we can
use the Thread_base parent class for the setup of the platform thread, and
afterwards create a Fiasco.OC specific cpu session client with the same cpu
session capability, Thread_base used for creation, to make use of the L4Linux
specific features of this interface (VCPU enabling, irq object creation etc.).

570156b38c l4lx: allocate memory in chunks
When L4Linux tries to allocate a dataspace of the size of its physical
memory, this allocation can fail, because the 'l4re_ma_alloc()' function
in the 'l4lx' library always tries to allocate a contiguous dataspace of
the given size and there might be no contiguous free area left.

With this patch, memory gets allocated in chunks: if the size to be
allocated exceeds the configured chunk size, a managed dataspace gets
created and filled with multiple memory chunks of at most the chunk size.

The chunk size is 16M by default and can be configured in an l4linux
config node:

<config args="...">
	<ram chunk_size="16M"/>
</config>

Fixes #695.

b38fee2867 L4Linux stability improvements
- search for alternative virtual address regions upwards, starting from
  the given start address, in the 'l4re_rm_attach()' and
  'Region_manager::reserve_range()' functions

- don't treat memory locations above 0x80000000 in l4linux's virtual
  address space as device memory

- align the start address of the vmalloc area according to the assumption
  in 'devicemaps_init()'

Fixes #414.

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.

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.

d233186900 L4Linux: hold queue lock in block driver (fix #395)
When finishing a block request in the L4Linux block stub driver,
we#ve to hold the queue lock before using __blk_end_request_all, or
simply use blk_end_request_all instead. Moreover, this commit simplifies
the lock/unlock behaviour when the block queue has to be stopped, or resumed.
Thanks to I. Ismagilov for these suggestions.

70dfe4fcd7 Fiasco.OC: forward CC, and CXX variables (fix #462)
When building the Fiasco.OC kernel, and L4Linux within the Genode build system,
forward the CC, and CXX variables. It might contain useful tools like ccache,
or distcc to speed up compilation. Moreover, don't delete the MAKEFLAGS when
building Fiasco.OC. It hinders parallel builds.

518cbc5a5f L4Linux: no linux-kernel memcpy in cxx (fix #446)
Certain symbols from the libgcc_eh library in cxx that is linked with the
L4Linux kernel were resolved by using kernel internal implementations.
This lead to errors because the complete Linux kernel is built regparm=3.
This patch prefixes the appropriate symbols in the Linux Kernel and its
modules. Moreover, it fixes some warnings introduced by the latest update
to gcc 4.7.

block-session's queue-size.

3e406a1077 Increase quota of USB driver
The memory allocation heuristics in the usb driver provided by dde_linux
changed with the recent commit 71b2b42936.
Apparently, the new variant requires a larger memory pool. Increasing
the quota is a temporary fix until the memory allocator gets revisited.

760f37fc86 Fiasco.OC: enable SMP for L4Linux
This commit comprises the following changes to enable L4Linux to use several
CPUs:
* change default configuration for x86 and ARM
* add atomic cmpxchg operation to l4re library
* implement l4_sleep (per thread)
* enable setting affinity for VCPUs and IRQs
* move "per CPU" section within linker-script (x86 only)
* introduce SMP run-script for pandaboard
* deactivate direct scheduler (Fiasco.OC syscall) access by L4Linux

a5ea6765d1 Fiasco.OC: several capability ref-counter fixes.
This commit fixes several issues that were triggered e.g. by the
'noux_tool_chain' run-script (fix #208 in part). The following problems
are tackled:
* Don't reference count capability selectors within a task that are actually
  controlled by core (all beneath 0x200000), because it's undecideable which
  "version" of a capability selector we currently use, e.g. a thread gets
  destroyed and a new one gets created immediately some other thread might
  have a Native_capability pointing to the already destroyed thread's gate
  capability-slot, that is now a new valid one (the one of the new thread)
* In core we cannot invalidate and remove a capability from the so called
  Cap_map before each reference to it is destroyed, so don't do this in
  Cap_session_component::free, but only reference-decrement within there,
  the actual removal can only be done in Cap_map::remove. Because core also
  has to invalidate a capability to be removed in all protection-domains
  we have to implement a core specific Cap_map::remove method
* When a capability gets inserted into the Cap_map, and we detect an old
  invalid entry with the dame id in the tree, don't just overmap that
  invalid entry (as there exist remaining references to it), but just remove
  it from the tree and allocate an new entry.
* Use the Cap_session_component interface to free a Pager_object when it
  gets dissolved, as its also used for allocation
