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.

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.

6c7a25d08c base-hw: use generic signal_session/connection.h
base-hw extended the signal quota in a specific connection
implementation, which just conceals other issues if quota upgrade is
triggered.

e717ad656f base-hw: preserve symbolic link bin/core
In this case "mv A B" works slightly different than "cp A B; rm A" as
symbolic links come into play. The statements should copy the contents
of A into the symboliv link at B (preserving it as is) and remove A. The
mv would replace the link B by the binary A.

Fixes #805.

d43d9900ab base-hw: Make memory_region_attr CPU-specific
This patch moves the implementation of the 'Arm::memory_region_attr'
function from the generic ARM code to the ARM v6/v7 specific code
to enable the customization of page-table bits depending on the
specific CPU core type. I.e., the ARM1176 apparently does not cope
well with setting the 'Tex::bits(2)' for MMIO mappings.

ce58a63fb6 Remove 'epit' from generic i.MX platform spec
Remove the 'epit' variable from the generic imx31 and imx53 specification,

library gets build for base-hw only.
Moreover, fix some const-ness issues in the platform_timer implementation
for the EPIT timer.

21de42c45d core: Introduce 'Address_space' interface
The new core-internal 'Address_space' interface enables cores RM service
to flush mappings of a PD in which a given 'Rm_client' thread resides.
Prior this patch, each platform invented their own way to flush mappings
in the respective 'rm_session_support.cc' implementation. However, those
implementations used to deal poorly with some corner cases. In
particular, if a PD session was destroyed prior a RM session, the RM
session would try to use no longer existing PD session. The new
'Address_space' uses the just added weak-pointer mechanism to deal with
this issue.

Furthermore, the generic 'Rm_session_component::detach' function has
been improved to avoid duplicated unmap operations for platforms that
implement the 'Address_space' interface. Therefore, it is related to
issue #595. Right now, this is OKL4 only, but other platforms will follow.

a99193ad90 Rework the internal lock interface
With this patch, the 'futex' syscall gets used for blocking and unblocking
of threads in the Linux-specific lock implementation.

The 'Native_thread_id' type, which was previously used in the
lock-internal 'Applicant' class to identify a thread to be woken up,
was not suitable anymore for implementing this change. With this patch,
the 'Thread_base*' type gets used instead, which also has the positive
effect of making the public 'cancelable_lock.h' header file
platform-independent.

Fixes #646.

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.

bcdc706f42 Unify 'ipc.h' and 'ipc_generic.h' across platforms
The distinction between 'ipc.h' and 'ipc_generic.h' is no more. The only
use case for platform-specific extensions of the IPC support was the
marshalling of capabilities. However, this case is accommodated by a
function interface ('_marshal_capability', '_unmarshal_capability'). By
moving the implementation of these functions from the headers into the
respective ipc libraries, we can abandon the platform-specific 'ipc.h'
headers.
