Alexander Boettcher 683832f461 base: avoid deadlock if invalid object is called
This avoids a deadlock if during issuing a printf the low level IPC fails.
. Printf uses an address space local lock and if we are trying again
to make a printf we deadlock forever ...

Alexander Boettcher 4e47cd2568 nova: catch exception when leaving thread::entry()
Catch exceptions and try to make a printf. If this also fails, catch
it and die causing some noise output in core to detect the situation.

Alexander Boettcher 4ae1faf14d base: add affinity support to pager construction
Propagating the affinity information is needed to allow for assigning
a pager thread that is local to the CPU of the to-be-created thread.

Norman Feske 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).

Christian Prochaska 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.

Alexander Boettcher 01d267e551 noux: calculate rm::attach parameters correctly
Previous commit denies the creation of regions larger then the dataspace.
Noux does it by setting the default size to the dataspace size without
subtracting the offset.

Alexander Boettcher 717be91e16 base: deny region creation exceeding size of a ds
The rm_session implementation expects that offset + size must be
part of one dataspace. Unfortunately the parameters are not checked
properly during an rm::attach.

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

Christian Prochaska 09049278a6 Round up RM session size to page granularity
Since RM sessions can be used as dataspaces and dataspace sizes are
supposed to have page granularity, RM session sizes should have page
granularity, too.

Josef Söntgen 505f4290ec base: activate Rpc_entrypoint explicitly in dtor

Rpc_exit.

Stefan Kalkowski 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.
