b1008df2c2 Patch by Alex Wilson: Added convenience methods for storing BAlignment and BSize
in BMessages. Also added type codes for them in TypeConstants.h. Closes ticket
#6302. Thanks!

e0b7c61c46 Closing ticket #4465:
Net_server starts services by invoking fork() followed by exec(). If the latter
fails (for instance because the service isn't installed), the forked child is
invoking exit(). This in turn unloads libbe, triggering static cleanup code in 
BMessage, which deletes a couple of message ports that were inherited from the
parent during the fork. After that, net_server was desparately missing those
ports and no longer worked reliably.
* in InitTerminateLibBe, we now register an atfork-(child-)handler, which
  takes care to re-initialize the static reply ports used by BMessage code
* added BMessage::Private::StaticReInitForkedChild wrapper and 
  BMessage::_StaticReInitForkedChild() implementation which overwrites the
  inherited port IDs with a set of own ports

d7a16b238f * Fully switch to the Haiku message format so that it is also used for on-disk
storage.
* Remove reduntant information from the header (field_count vs. fields_size).
* Remove checksums previously used to validate the message passing by area
  mechanism.
* Move variables that are purely used by the instance out of the header and into
  the BMessage object.
* Use more sensible types for the different message fields.
* Reduce some field sizes to realistic values.
* Make size_t values into uint32 values so the message format will not change
  when later moving to 64 bits.
* Pack the structures used for flat message storage so it doesn't change
  because of padding.
* Fix message passing by area. It never worked because the created area was
  never actually filled with any data!
* Some more allocation checks with graceful fallbacks (should be all now).
* Some more checks for negative index values (should also be all now).
* Make printing more inline with how the rest of the class works and make some
  of the output more consistent.
* Also add the new unsigned types to PrintToStream() output.
* Fix printing of unknown types and invalid BMessages, it would always have
  printed only the first entry respectively the same error.
* Added some clarifying comments.
* Cleanup.

3c6372b44a Rename BMessage::CompareData() to HasSameData() as this makes more sense for the
bool return type. Did I mention this was an unstable Haiku extension?

5b25b917f9 Introduce BMessage::CompareData() which is a Haiku API extension. It compares
the data of two BMessages and allows recursive comparison (BMessage inside
BMessage). Note that using this API might require you to recompile your app in
the path to R1.

a433b9febf Rewrite and activate message passing by area. Passing by area works now with
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.

f9d99406ae Fixed build under Dano (and probably Zeta, too); our headers used entry_ref resp.
BDirectory without declaring it first. Since that's an actual bug, I made the
changes in the Haiku headers, and copied them back to the build headers.

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.

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.

deal properly with flattened BMessages as well.

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.
