Under some circumstances, the diagnostic message in the exception signal
handler was not printed. This could happen due to a dead lock in the
console library if the console code itself produces the exception while
possessing the mutex, e.g., by exhausting a undersized stack. Now, we
directly write to the log session via the stdout_write() hook or use
raw_write_str() in core.
This patch improves the decorator in two ways. First, it enables the
assignment of window colors depending on the window labels. This
configuration can be changed dynamically. Second, it adds the handling
of window controls for closing, maximizing, minimizing windows.

This patch supplements the existing focus reports with the new attribute
'active', which indicates recent user activity when set to "yes". This
information is consumed by the clipboard to dynamically adjust its
information-flow policy depending on the user activity.
Issue #1712
This patch moves the formerly internal classes of the report-ROM service
to the public location os/include/report_rom/ so that they can be reused
by other components such as the upcoming clipboard.
This overload of the value member eases the retrieval of Genode::String
objects from XML attributes. So we won't need to deal with C-style
character buffers anymore.
The utilities in os/session_policy.h used to be tailored for the
matching of session arguments against a server-side policy
configuration. However, the policy-matching part is useful in other
situations, too. This patch removes the tight coupling with the
session-argument parsing (via Arg_string) and the hard-wired use of
'Genode::config()'.
To make the utilities more versatile, the 'Session_label' has become a
'Genode::String' (at the time when we originally introduced the
'Session_label', there was no 'Genode::String'). The parsing of the
session arguments happens in the constructor of this special 'String'.
The constructor of 'Session_policy' now takes a 'Genode::String' as
argument. So it can be used with the 'Session_label' but also with other
'String' types. Furthermore, the implicit use of 'Genode::config()' can
be overridden by explicitly specifying the config node as an argument.
Defer destruction of threads which tries to self-destruct. Check an perform
cleanup of such threads during pthread_cancel and pthread_create.
Issue #1687
Until now, the CLI monitor and the laucher allowed the user to explitly
kill subsystems but both used to ignore gracefully exiting subsystems.
It was the user's job to remove the remains of those subsystems. The
patch takes the burden of manually killing exited subsystems from the
user.
Fixes#1685
Instead of white-listing floppy controllers, certain SCSI controllers
as well as ISAPnP etc. pp. remove the diagnostics and print each access
if verbose is set.
Fixes#1726.
Instead of using the alarm_timer thread we use our own timer thread
that uses a kernel semaphore on Nova. On all other platforms a timer
connection and trigger_once is used.
Fixes#1727.
