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.
Issue #905
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.
fix#935
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).

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_*.
Fixes#937.
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.
Issue #947
Since we switched to using C++11 by default, the webkit-related
parts of qt4 failed to compile because of C++11 compatibility
issues. This patch disables the use of C++11 for the offenders.
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.
Fixes#299.
A timer session is now used instead of a jiffy counter. This way, libSDL
can use a time source that is not bound to the granularity our libc's
nanosleep implementation. Currently, the granularity of nanosleep is in
the order of 10 milliseconds, which is far to coarse for the use of
SDL-using applications such as DosBox.
Fixes#934.
