819e54f860 run: change resolution of virtualbox_auto_disk
We changed the test hardware and the new one does not support 1400x1050 anymore.
Choose some conservative resolution since this is anyway a auto test nobody
is really looking at the screen output.

0918c6006b stdcxx: build 'tinfo.cc'
The 'tinfo.cc' file needs to get built, because it implements
'std::type_info::operator==(std::type_info const&) const', which
is needed by the 'icu' library on ARM.

Fixes #1109.

7d232cafb0 timer: fix corner case if counter is 0
If counter drops to 0, the wrap flag is set also. That means we have actually
no wrap around. The patch avoids to add too much time to the elapsed time
variable.

2f3b67c9e0 nitpicker: Fix implementation of Mode interface
The generalization of nitpicker's graphic backend changed the interface
of 'Mode::forget', which is a (non-pure) virtual function implemented
by 'User_state::forget'. Unfortunately, the signature change was not
applied to 'User_state::forget' so that the actual implementation was
no longer called. This inconsistency remained unnoticed because there
is a default implementation of the virtual function.

The effect of the omission of the 'User_state::forget' call was a
dangling pointer ('User_state::_pointed_view').

Lesson learned: Always annotate functions with the C++11 'override' when
implementing virtual functions.

e6c7596af5 ldso: flush the log console in 'errx()'
The error message given to the 'errx()' function does not always contain a
'\n' character. Adding 'printf("\n")' ensures that the message appears on

2e5cb2ea82 Use do statement in PDBG and PWRN
The do statement ensures the macros to generate just one expression that
is compatible with any programming construct. The concrete bug was

  if (cond)
    PDBG(...);
  else
    ...

which was expanded to

  if (cond)
    if (DO_PDBG)
      Genode::printf(...);
  else
    ...

This is obviously wrong as the *else* branch is then connected to the
second *if*.

0b7ea4abab Genode::Connection: Mark as noncopyable
When an object derived from Genode::Connection is copied we had
strange issues. An example is that the first RPC invocation works
correctly but the second one blocks or even delivers incorrect data.

We can avoid this issue if the object is always passed by reference.
Ensure this by deriving from Genode::Noncopyable.

8ce197d7fa hw: do inter-processor interrupt only when needed
The processor scheduler can determine without much overhead wether
the currently scheduled client becomes out-dated due to the insertion
of another client. This can be used to safe inter-processor interrupts
when a remote insertion doesn't imply an update of the currently
scheduled client.

18cee192e2 hw: don't do redundant inter-processor interrupts
At least with the ARM generic interrupt controller, inter-processor interrupts
are edge triggered and banked for all source processors. Thus it might be
possible that such an interrupt gets triggered redundantly until the targeted
processor is able to grab the kernel lock. As we're only interested in making
a processor recognize accumulative updates to its scheduler, we can omit
further interrupts if there is one pending already at the targeted processor.

044a109c3a hw: reset scheduling timeout implicitely
This is needed as soon as we do inter-processor interrupts to
inform a processor about a remote modification in its scheduling plan.
In this case we can not explicitely decide wether to reset timer
or not. Instead we must decide it according to the choices of the
scheduler before and after the modification.

6525ec5951 Simplify Framebuffer::Session interface
This patch removes the 'Framebuffer::Session::release()' function from
the interface to make the mode-change protocol consistent with the way
the Rom_session interface handles ROM-module changes. That is, the
client acknowledges the release of its current dataspace by requesting a
new dataspace via the 'Framebuffer::Session::dataspace()' function.
