Stefan Kalkowski 040cd95580 noux: fix context-area re-initialization in fork 
With commit e74b53d5dd the fork semantic in noux
changed slightly, and broke platforms like hw & sel4, where the UTCB is mapped
directly into the thread's context area. The change moved the re-initialization
to a point where the new noux process' thread stack-pointer was already switched
back to the context area. But to re-initialize the context area RPC calls must
be done, and the UTCB must be used therefore. On the other side the UTCB is
found implicitly by the stack-pointer, whereby a stack-pointer located in the
context-area refers to a UTCB that is expected to reside in the context-area
as well. But the UTCB gets overlayed inside the context area by the
context-area's re-initialization - we've come round in a circle.

This commit rolls back the move of the re-initialization routine. To preserve
the intention of the original commit, the context-area location is stored in
a static variable, so that the Native_config API is not needed anymore.

Fix #1851

README 

This directory contains ports of popular 3rd-party applications to Genode.

The 'ports' repository follows the line of the 'libports' repository.
For instructions about downloading and building 3rd-party applications,
please refer to 'libports/README'.


Dependencies from other repositories
------------------------------------

Application provided by the 'ports' repository typically expect a rich
runtime environment, including shared libraries provided by the 'libports'
repository. Hence, 'ports' depends on 'libports'.
