app_server: store the brightness with the current screen config if absent

when no screen configuration is found, the preferred mode is then selected,
and we now use this as current screen configuration. Otherwise, the user
would adjust the brightness, but it would never be stored for the next boot.

app_server: turn DPMS on only after setting a valid mode

It's not allowed to enable the screen before having set a mode. At least
in the case of the intel_extreme driver, this creates some problem. Move
the call just a bit later in the init process, where the mode is already
set.

app_server: don't reset brightness when switching workspaces

app_server: save/restore screen brightness settings

The brightness is saved in the screen configurations of the first
workspace. For now, all screens get the same brightness (I can't get
screen IDs to work today). Since we only support setting the brightness
for laptop displays for now, this shouldn't matter. It can be fixed when
app_server gets actual multiple display support.

app_server: added more debug output on screen change problems.

* Adding a remote desktop interface that operates on app_server drawing
primitives by providing a RemoteDrawingEngine and a RemoteHWInterface.
Not really optimized yet, still a bit WIP.
* Adding corresponding infrastructure like a blocking ring buffer and network
sender/receiver that are attached to the buffers to feed/drain them as well
as a RemoteMessage helper that provides a message based interface.
* Adding target screen concept to request an app to be run on a specific screen.
It's controlled by the TARGET_SCREEN environment variable which is added on
the app side and sent to the app_server.
* Right now only remote target screens are supported, in which case a new
RemoteHWInterface is created that tries to connect to the given host:port.
* Fix shape bounds when drawing, they need to be translated by the pen position
and converted to screen like the points as well. Wasn't visible though as the
bounds weren't used in the normal DrawingEngine.

* Rewrote screen configuration management: VirtualScreen doesn't have anything
to do with the configurations now, instead, there is a separated
ScreenConfigurations class that maintains all known screen_configurations
per workspace (and the Workspace::Private class has two of them, one for the
current modes, one for the stored modes).
* Added Desktop::{Get|Set}ScreenMode() methods, ServerApp now only calls those.
* Getting and setting of anything else than the current screen is now supported.
* This change also fixes that a temporarily set screen mode was not being
restored on workspace switch.
* Also, the Deskbar now seems to have the wrong location a lot, which is
something that should be easily fixable therefore. I will look into this next.
* Got rid of the unhandy screen_id structure server side, and in BPrivateScreen;
we now just use an int32 - the next API break should definitely replace the
screen_id with a simple typedef.

fixed BScreen mode.flags handling. This is now compatible with BeOS, and fixes for instance the use of Dualhead Setup for the Matrox and nVidia driver which make use of 'free' flags. A modeset command should be relayed to the accelerant even if it differs by just a single bit: the accelerant best knows how to handle this. Remark: Haiku's screen preflet refuses to set modes once a virtual screen is set since it doesn't recognize the currently set mode. I guess that could be fixed.

* Renamed the "simple" mode setter Screen::SetMode() variant to SetBestMode();
it can also no longer create a default mode.
* This SetBestMode() function now follows a similar logic than the boot loader,
that is, only the width must not deviate, all other values are chosen as
close to the original as possible.
* VirtualScreen::AddScreen() now follows the same logic as the boot loader in
case no configuration was found, and the current screen has no preferred mode
(for example via EDID). That is, it will first try 1024x768, and then 800x600.
* This means there is no mode change anymore when switching from the boot
loader to the app_server in Qemu and VMware.

* Linking against $(TARGET_LIBSTDC++) instead of libstdc++.r4.so.
* Local variables shadowing parameters.
* Default parameters in function definitions (as opposed to function

* "new (sometype)[...]" must read "new sometype[...]", even if sometype is
something like "const char *".
* __FUNCTION__ is no longer a string literal (but a string expression), i.e.
'printf(__FUNCTION__ ": ...\n")' is invalid code.
* A type cast results in a non-lvalue. E.g. "(char *)buffer += bytes"
is an invalid expression.
* "friend class SomeClass" only works when SomeClass is known before.
Otherwise the an inner class with that name is considered as friend.
gcc 4 is much pickier about scopes.
* gcc 4 is generally stricter with respect to type conversions in C.
