1dd2a199a5 nova: support cap receive window of various sizes
Open a capability receive window according to the number of the capabilities
expected as out parameter per RPC function.

Typically the number of capabilities expected during the reply of a RPC/IPC
call is 0 to 1. Before this patch ever a capability receive window of 4 has
been opened.

On Nova the capability selectors of receive windows must be naturally aligned
to the size/order of the expected capabilities. This leads until now to the
issue that the left over 3 capabilities couldn't be reused for new IPCs since
they are not naturally aligned to 4.

347ff635b3 fiasco: fix SYSTEM_TARGET prefix in l4env config
The config file is interpreted in a bash script. So, SYSTEM_TARGET is a
bash variable, i.e., ${SYSTEM_TARGET}.

Fixes #946. Related to #490.

909ab8dcd0 hw: communicate page faults via signals
Enable routing of thread events to signal contexts via
Kernel::route_thread_event.

Replace Kernel::set_pager by Kernel::route_thread_event.

In base-hw a pager object is a signal context and a pager activation
is a signal receiver. If a thread wants to start communicating its page
faults via a pager object, the thread calls Kernel::route_thread_event with
its thread ID, event ID "FAULT", and the signal context ID of the pager object.
If a pager activation wants to start handling page faults of a pager object,
the pager activation assigns the corresponding signal context to its signal
receiver. If a pager activation wants to stop handling page faults of a pager
object, the pager activation dissolves the corresponding signal context from
its signal receiver. If a thread wants to start communicating its page faults
via a pager object, the thread calls Kernel::route_thread_event with its
thread ID, event ID "FAULT", and the invalid signal context ID.

Remove Kernel::resume_faulter.

Move all page fault related code from generic kernel sources to CPU
specific cpu_support.h and cpu_support.cc.

1c6c90fed5 core: provide signals before other services
Provide core-local signal service before other services to enable the use
of signal connections while initialzing the other services. This has been
introduced due to the use of the signal framework by the pager lib in
base-hw (RM service).

9bc42ecd87 ports: native version of DosBox
DosBox is DOS-Emulator which is mainly used for playing old
DOS games on POSIX systems and newer Windows versions.

This port of DosBox runs natively on Genode by using its
SDL backend. It is currently only works on x86_*.

1ed4b9fef9 Use log_terminal in noux.run script
This patch changes the noux.run script to use the new log_terminal
component instead of an UART driver. Besides being a nice way to test
the log_terminal service, the new version is much simpler and it just
became compatible to Linux as it no longer relies on an UART driver.

parts of qt4 failed to compile because of C++11 compatibility
issues. This patch disables the use of C++11 for the offenders.

8b8e3ef7a5 noux: calculate inode value from path
There are programms that use struct stat's st_ino field to check certain
conditions. Since we are using multiple filesystems in a noux session we
cannot use the inode number which the actual filesystem provides.
Therefore we calculate a random inode number by hashing the stated path.
