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.

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.

8d9e7d0da2 lwip: set some reasonable default rcv buf size
lwip reports via getsockopt the size of the default size of the receive buffer
to the netperf server. lwip returns 2GB and netperf server uses this value to
allocate some buffers - which of course fails with out of memory.

Reduces the "default size" to some smaller value.

With the commit we are not forced anymore to (but still can) use specific
netperf client options regarding memory allocations of the receive buffer.

e35dbd3353 run: add TCP_MAERTS to netperf test
MAERTS is STREAM backwards and effectively lets the netserver sends the packets
to the netperf client. So, TCP_STREAM measure the receive performance of the
lwIP stack on Genode and TCP_MAERTS the send performance of the lwIP stack
on Genode.

179f742924 ports/libports: Handle failed integrity checks
This patch makes the handling of failed integrity checks of 3rd-party
packages more robust. Previously, a once failed 'make prepare PKG=curl'
would not leave any trace of the verification state. Hence, a successive
attempt to perform the 'make prepare' step again succeeded even if the
signature check failed.

To solve this problem, the outcome of a successful signature check is
represented by a tag file called 'download/<archive-name>.verified'.
Because the rule for extracting the archive depends on the .verify tag
file, the extraction step is not performed until the signature check
succeeds.

33c5469b92 vancouver: Improved PS/2 mouse backend
The previous version of the PS/2 mouse backend manged mouse motion
events in a strange way, effectively throwing away most information
about the motion vector. Furthermore, the tracking of the mouse-button
states were missing. So drag-and-drop in a guest OS won't work. The new
version fixes those issues. For the transformation of input events to
PS/2 packets, a the Genode::Register facility is used. This greatly
simplifies the code.
