process group. This fixes bug #996.
* As a result, the process group stuff and wait_for_child() got much simpler;
get_death_entry() and update_wait_for_any() could go away completely.
* If a team goes away, all of its children are now "reparented" to the kernel team,
instead of the team's parent - this follows common implementations (and POSIX if
I understand it correctly), but not BeOS anymore. The OpenGroup Base says this
about this topic: "If a parent process terminates without waiting for all of its
child processes to terminate, the remaining child processes shall be assigned a
new parent process ID corresponding to an implementation-defined system process."
* We wait too long in wait_test_4 which at least puts us on par with Linux; see
comment in _user_setpgid().

broken (see bug #996), but less broken than Be's.
Also the Linux implementation is not perfect, as test 4 reveals: it waits for a
child with a certain process group, even if there is no child around anymore (because
the last child changed its process group. However, it will still return (and report
the correct error code) once this child exits.

* Fixed comment, as Haiku now behaves properly at least for most cases :-)
* Style guide update.

I'm considered splashing it up a bit by adding parameters for colors, etc, but
this will make a good baseline.

So the mechanism with the global variable did not work for R5 what caused two USB stacks and host controller drivers to be active concurrently which resulted in completely unpredictable results.
This kind-of-inelegant fix was all I could come up with, if someone has a better idea please send it this way.

- Fixed some formatting in the recently added resizing code.
- Changed the operation name for rotating counterclockwise to use that name
instead of anticlockwise. This makes the code consistent with the GUI.
- Reformatted the constants header to use an enum. Also removed the empty
constants cpp file.
- The QuitRequested handler in the app did not ask the windows to close, which
could cause modified images to be closed without prompting the user. Now it
does, which makes ShowImage more user friendly.
Changes to the image view:
- Added a member for keeping track of the type of image. This is mostly used in
properly updating the window's status bar when the image is changed (flipped,
rotated, etc.) This removes some hacky code I added before :)
- Removed the status parameter in the Notify method since it was only used for
the above image type status updating.
- Removed a redundant if in the mouse up handler.
- The key down handlers for moving to the next and previous image did not
properly prompt the user if the image had changed. I fixed this by sending a
message to the window where the prompting code resides. When adding this I
also created a few helper methods for sending messages to the window, which
removed some (small) repeated code through-out the class.

ECHILD in case it doesn't. This fixes bug #995.
* Added a TODO item for solving bug #996.
* wait_for_child() did not release the team lock and restore interrupts in case
the child you wanted to wait for didn't exist...
* with child > 0, wait_for_child() will now check if its really a child of yours,
and not just in the same process group.

2048 bytes. This should fix bugs #993 and #997.
On BeOS R5 asking for 2 bytes too much wasn't a problem, as we
only need the first page_entry, and it didn't return any Error.

crashes at a later time. I observed one error at 8033a802, but the address
was allocated by the driver and should have been fully locked.

C style ones, as this is a C header, too (and a very basic one).

vmdkheader tool. New pseudo target haiku-vmware-image to build it.
Image default name is "haiku.vmdk", adjustable via the
HAIKU_VMWARE_IMAGE_NAME variable.

Tested with VMware Player 1.0.3 on linux and works.
Can also be used to create a haiku.vmdk file from an existing haiku.image file:
rm haiku.vmdk
generated/objects/linux/x86/release/tools/vmdkheader/vmdkheader -h 64k -i100M haiku.vmdk
cat generated/haiku.image >>haiku.vmdk

feel free to change that ;-)
* Cleaned up existing headers.
* Coding style guide update to BBufferIO (renamed m_* members to f*).

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.
