9dbe170a69 Implemented direct message passing for local targets; this fixes a deadlock
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.

67bdea52ce hope no one minds with this Dano-like version of BMessage::PrintToStream()

2bf8fb3a96 Putting Message4 into place to become the new BMessage implementation. Will cleanup USING_MESSAGE4 now.

16ba0dc5ca Removing old BMessage implementation. Message4 will replace it in the next commit.
This will allow to fix message related problems like drag and drop and scripting.

4ceb1e519c * reverted Adi's premature changes to BWindow and restored _DetermineTarget() and
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.

1ba67cc8c6 * almost rewrote BMessageQueue; simplified code, removed over-extensive documentation,
cleanup.
* 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.

758b1d0e05 Fixes that make Haiku build with gcc 4. Mainly out of the following
categories:
* Missing includes (like <stdlib.h> and <string.h>).
* 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.

efbea3a07a Moved the functionality to flatten and unflatten a BMessage header into
a separate class. This allowed to improve _SendFlattenedMessage() to
deal properly with flattened BMessages as well.

534ef684d9 Turned _init_message_(), _delete_message_(), and _clean_msg_cache_() into
proper private static BMessage members and made them accessible through
BMessage::Private. Got rid of unused _reconstruct_message_().

377872556d * Added support for unflatting from flattened KMessages. At least when
a buffer is given.
* Added method for sending flattened messages. The KMessage support is
  complete, but for BMessages this is a bit tricky. We currently unflatten
  the BMessages and send those.

e9e500cb9e Minor tweak to BHandler::UnlockLooper()
Added calls to _init_message_(), _delete_message_(), and
_msg_cache_cleanup() to InitTerminateLibBe.cpp
Finished first implementation of BMessage::SendReply(), BMessage::_send_(),
and BMessage::_send_message()
Add BMessage to app.src, removed BBlockCache from support.src.
New BMessage::Private class has functions for twiddling BMessage internals

80e966963f Little tweaks and fixes too numerous to count, but mostly involved with
adding entry_refs and BMessages.  Lots of stuff for specifiers and also for
sending replies (with thanks to Mike Nordell).
