bb00aebc9e hw & signal: consider initial SLAB blocks
By now Signal_session_component has allocated initial SLAB
blocks in constructor, wich crashed with the root
components assumptions about the RAM quota needs of
session creation. Thus, if the background allocator was already
exhausted from component allocation the session was created
with broken initial SLAB blocks.

9b28395f0d noux: construct new child only if binary is valid
If a script is executed which uses a interpreter that does not exist the
construction of the child fails and potentially leaks memory because the
wrong delete operator is called.
Therefore the binary dataspace of the script and the binary dataspace of
the interpreter are now checked before a new child will be created.

Fixes #812.

5ec07614e8 init: Read affinity assignments from config
The assignment of affinities consists of two parts, the definition
of the affinity space dimensions as used for the init process, and
the association sub systems with affinity locations (relative to the
affinity space). The affinity space is configured as a sub node of the
config node. For example, the following declaration describes an
affinity space of 4x2:

<config>
  ...
  <affinity_space width="4" height="2" />
  ...
</config>

Subsystems can be constrained to parts of the affinity space using
the '<affinity>' sub node of a '<start>' entry:

<config>
  ...
  <start name="loader">
    <affinity xpos="0" ypos="1" width="2" height="1" />
    ...
  </start>
  ...
</config>

6d837c9e26 Attach affinity information to session requests
This patch extends the 'Parent::session()' and 'Root::session()'
functions with an additional 'affinity' parameter, which is inteded to
express the preferred affinity of the new session. For CPU sessions
provided by core, the values will be used to select the set of CPUs
assigned to the CPU session. For other services, the session affinity
information can be utilized to optimize the locality of the server
thread with the client. For example, to enable the IRQ session to route
an IRQ to the CPU core on which the corresponding device driver (the IRQ
client) is running.

5fe29e8e4a Express affinities via Cartesian coordinates
This patch introduces new types for expressing CPU affinities. Instead
of dealing with physical CPU numbers, affinities are expressed as
rectangles in a grid of virtual CPU nodes. This clears the way to
conveniently assign sets of adjacent CPUs to subsystems, each of them
managing their respective viewport of the coordinate space.

By using 2D Cartesian coordinates, the locality of CPU nodes can be
modeled for different topologies such as SMP (simple Nx1 grid), grids of
NUMA nodes, or ring topologies.

70d0b00dde nova: update to kernel revision r3
r3 contains the recent Nova upstream kernel version plus the Genode specific
extensions and changes as known from r2.

Additionally, the r3 branch

* contains the assign_pci patch now directly,
* adds support for cross CPU IPC,
* fixes some issues with freeing up kernel memory part of r2 and
* update the documentation a bit.

956cab5fdb noux: Keep track of how dataspaces are used
This patch eliminates the "no attachment at..." warnings, which
were caused by a use-after-free problem of dataspaces. When a
dataspace was destroyed, the users of the dataspace were not
informed and therefore could not revert possible attachments to
RM sessions. The fix introduces a callback mechanism that allows
dataspace users (i.e., RM regions) to register for the event that
a dataspace vanishes.

The following types of dataspaces are handled:
* RAM dataspaces
* ROM dataspaces
* The process binary
* The binary of the dynamic linker
* Args dataspace
* Sysio dataspace
* Env dataspace
* managed RM dataspaces

The handling of ROM dataspaces is still not complete. When forking,
the ROM dataspace of the parent process gets just reused without
creating proper meta data ('Dataspace_info') for the forked process.
Similar issues might arise from other special dataspaces (e.g.,
args, env, sysio).

This patch removes all "no attachment at..." warnings except for
one (an attachment at 0).

dc177e037d bash: don't call 'check_dev_tty()'
The 'check_dev_tty()' function calls 'ttyname()', which calls the pthread
stub function 'pthread_main_np()', which prints a 'not implemented'
message. Calling 'check_dev_tty()' doesn't seem to be necessary, so this
patch removes the call.

717be91e16 base: deny region creation exceeding size of a ds
The rm_session implementation expects that offset + size must be

properly during an rm::attach.

During an detach memory behind the actual region can be unmapped by such
bogus region entries.
