the new sematic of transfer_area so a message area is transfered into the right
teams' address space and it does not need to be cloned there anymore. Passing
by area is only used for messages bigger than a certain size (currently
hardcoded to 40KB) which should be somehow bound to the max port message size.
This makes passing large messages (i.e. > the port limit) possible, so for
example copy&paste of long text, image data, etc. should now work.
Got rid of the fClonedArea member as it is not necessary with the new design,
renamed shared_area to message_area in the private message_header, avoid
an unnecessary allocation of the header for the copy constructors, check
allocations in a few more places and some minor cleanup.

changes in the Haiku headers, and copied them back to the build headers.

* _WindowAt() and _CountWindows() now have an individual version of that
code which should be magnitudes faster.
* _WindowQuitLoop() no longer handles hidden windows specially - instead,
it now walks the window list in the correct direction which should fix
the issues.
* Also, it now uses WindowAt() and thus has an up-to-date view of the
window list (it will no longer ignore new windows).
* And finally, it will no longer dereference an unsafe pointer (for
BWindow::IsFilePanel()).

this fixes bug #1005. As a result, the Disks icon will now appear in file panels
when you change that setting with a panel open.
* _ObserverList is now in the BPrivate namespace (and renamed to ObserverList).
* its BHandler map is now only temporarily used for handlers that do not belong to
a looper yet; when BHandler::SendNotices() is called, they will be transferred
into the BMessenger map.
* Invalid messengers are now removed from the map when encountered.
* Added TODO comments about a possible reference counting if a handler is added
twice to a list (right now, this will be ignored).
* All {Start|Stop}Watching() methods are now more or less safe to be used in low
memory situations (adding some items to the map can still throw an exception...).
* Renamed BHandler::InitData() to _InitData().
* Some refactoring and cleanup.

with PostMessage() in case the message queue is full.
Some notes:
* for synchronous replies, we don't use this mechanism yet, but it could be
extended to do that as well.
* the code looks so complicated because we need a way to access the looper's
queue without locking it (to prevent deadlocks); like Dano's solution, I've
abused BTokenSpace to store a BDirectMessageTarget with a BHandler.
* we also need to decouple the lifetime of a looper's queue from its target,
as we cannot lock the looper, and therefore, can't guarantee it stays valid
as long as we're accessing it outside of BLooper.
* init_clipboard() now needs to be done after the global constructors have
been called - since sending messages now needs gDefaultTokens to be initialized.
Since this is done per image, it shouldn't cause any troubles, though.
* some minor cleanup, removed unused _msg_cache_cleanup_() and friends.

* Got rid of unused BLooper members
* renamed fTaskID to fThread
* Removed private and deprecated AddLooper()/RemoveLooper()/... stuff; BLooper is now
directly calling BLooperList methods.
* Got rid of extensive and useless comments
* Made a few TODOs more clear
* Merged InitData() and InitData(...) to _InitData(...)
* BLooper::Team() now uses BPrivate::current_team(), sTeamID is gone now.

update its looper thread.

Switcher now works as expected.
* Renamed TRoster::ActivateApp() to UpdateActiveApp(), as the app is already activated
at that point (the registrar only keeps track of it).
* BWindow::DispatchMessage() now calls the new BRoster::Private::UpdateActiveApp()
method when it receives a B_WINDOW_ACTIVATED message.
* Added BRoster::_UpdateActiveApp() which calls the new B_REG_UPDATE_ACTIVE_APP.
* Removed now unused B_REG_ACTIVATE_APP.
* Minor cleanup.

in several steps:
1. early pre-registration with the registrar ("I wanna launch the
app, make sure noone interferes.")
2. load the app image
3. finish pre-registration with the registrar ("I have launched
the app, here is its team ID.")
4. start app main thread
5. send "on launch" messages to the app (argv, refs, others)
If the app is already running or being launched, 1. fails with a
conclusive error code and returns the team ID and the pre-registration
token of the app. Steps 2 - 4 are skipped and only the messages are
delivered using the team ID returned by 1.
This change fixes a race condition: The failed early pre-registration
request obviously cannot return the team ID, if the other thread
launching the app has not finished step 3 yet. Thus the argv/refs
message would not get delivered and Launch() would not return the
correct team ID.
Now we wait for the pre-registration to be finished in this case, using
the former _IsAppPreRegistered() mechanism, which already provided
such a waiting feature for one request. It has been extended to
accomodate an arbitrary number of waiting requests and renamed to
_IsAppRegistered().
This fixed bug #763.

translators are installed via BTranslatorRoster::StartWatching().
* Fixed GetTranslatorData() - some hooks are only optional (this puts the
JPEG, GIF, and some other translators back into the game).
* Made BTranslatorRoster::Default() thread-safe.
* Improved documentation.

read-only area shared between the Desktop and all applications.
* Right now, this area only contains the desktop colors, ie. B_PANEL_BACKGROUND_COLOR
etc.; ui_color() no longer needs to ask the server for these colors.
* The ui_colors are now maintained by DesktopSettings, though ColorSet is still there.
* The default colors are now hardcoded once and for everyone in InterfaceDefs.h, ie.
the app_server uses them as well.
* Desktop::Init() can now also return an error (but that is not yet accounted for).
* Cleaned up InterfaceDefs.h.
* Fixed wrong include in moreUTF8.h.

* all cursors owned by a team are visually different,
or (iaw) an already existing cursor is reused when
it is set by the client again
* changed various occurances of cursor data from "int8*"
to "uint8*"
* ServerCursors also remember the R5 data from which
they were created
* the reference counting and destruction of
ServerCursors changed: The cursor knows it is attached
to a CursorManager and one can simply use
ServerCursor::Acquire() and Release() and the reference
counting and everything is being taken care of
* destroying a ViewLayer will now correctly release a set
ServerCursor
* fixed a race condition when setting a cursor through
BView::SetViewCursor(): If the client code looks like this:
BCursor cursor(cursorData);
someView->SetViewCursor(&cursor, false);
there is a relatively high chance the BCursor destructor
told the ServerApp thread to destroy the cursor before
the ServerWindow thread got to "acquire" the cursor for
use by the view layer. The very same problem is likely the
reason that SetViewCursor works to unreliably on R5, even
when the "sync" flag is set to "true" (although it should
theoretically work in that case).
all these fixes make WonderBrush work fine again with the
new support of custom cursors.... coded by axeld and myself
(the joys of pair programming :-)

* Reordered some functions
* Area messages can now be unflattened instead of using the private _Reference and a special port code
Passing by area is now mostly working but it's not yet enabled. I will have to conduct performance tests first to see if and starting at what messagesize the overhead is reasonable.

* Fixed a myriad of bugs all over the place, ranging from locking errors to
deleting objects that don't belong to the one deleting them (hello HWInterface!)
* Almost all ServerWindow cursor stuff was broken; I've replaced all commands
to set a cursor with a single one AS_SET_CURSOR.
* Renamed some cursor commands.
* Changed the (broken) way ServerApp::fAppCursor was maintained - the application
cursor is now NULL as long as possible.
* Removed superfluous ServerCursor app signature stuff.
* The BApplication will no longer duplicate the default/I-beam cursors, it will
just reuse the default ones which now have fixed tokens.
* As a result, changing the cursor is now working as expected, closing bug #102.
* Rewrote Cursor.h, renamed private members to match our style guide.
* Minor cleanup.
What's still left to be done is reference counting the cursor objects to make them
work right and reliable.

* attachView() is now called _CreateSelf() and creates the app_server
view counterpart for itself, and no longer for a child view.
* removed superfluous deleteView().
* moved drawing from BWindow::DoUpdate() to BView::_Draw().
* made the recursive hook call functions consistent.
* fixed BWindow::DispatchMessage() to send public messages to the intended
target (instead of always handling them itself directly).
* DispatchMessage() no longer eats unmapped key events that were targeted
at the window directly.
* B_KEY_DOWN and B_KEY_UP events are now send to the target view as well
(this couldn't work before as BMessages were broken with B_PREFERRED_TOKEN).
* the default button is now correctly targeted by BWindow::_DetermineTarget()
(previously, the enter key was hacked to get through via _HandleKeyDown()).
* removing a view now also makes sure it won't have focus any longer.
* also, the DetachedFromWindow() hooks are now called first, so that any
changes made there cannot mess up our window anymore.
* removed BView::SetPattern(); _UpdatePattern() now does its job.
* renamend private methods to match our preferred style.
* removed unused methods and variables.
* more consistent naming overall.
* removed _PR3_COMPATIBLE_ stuff - there is definitely no need for us to be
compatible to that one.

task_looper() again.
* removed BMessenger::fPreferred - whenever you had to specify "usePreferred" separately,
you don't have to do that anymore - use B_PREFERRED_TOKEN instead.
* fixed BTokenSpace::GetToken() semantics: it will no longer touch the "object" argument
in case of failure.
* Introduced a BWindow::_DistributeMessage() that will be part of the event dispatcher
counterpart to the app_server (the other will be _DetermineTarget()).
* Made it easier to use Michael's Message4 implementation: just add the following line
to your UserBuildConfig:
AppendToConfigVar DEFINES : HAIKU_TOP src : USING_MESSAGE4 : global ;
* Introduced ServerWindow::HandlerMessenger() and FocusMessenger() - the first will
target the client handler, while the other will target the preferred handler of the
client looper (usually the view having focus).
* Fixed dano message unflattening in the Message4 code.
* Changed BMessage::PrintToStream() to no longer use macros in the Message4 implementation.
* I hope that's all - it's a huge change, but it's all connected.

* made BMessageQueue::IsLocked() const - the non-const version is still provided
for binary compatibility.
* Both BMessageQueue::FindMessage() versions are now thread safe, the queue's BLocker
is now mutable to allow for this.
* renamed BMessage::link to fQueueLink as the "Message4" implementation uses it.

* Linking against $(TARGET_LIBSTDC++) instead of libstdc++.r4.so.
* Local variables shadowing parameters.
* Default parameters in function definitions (as opposed to function
declarations).
* All C++ stuff (nothrow, map, set, vector, min, max,...) must be imported
explicitly from the std:: namespace now.
* "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.
