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.

* we now always flush the TLBs after having unmapped some pages.
* vm_soft_fault() could traverse to a source cache while it was being collapsed
by vm_cache_remove_consumer() - this is now no longer possible as the latter
marks the cache as busy when doing so, and the former now tests this flag and
locks the cache (via the new fault_acquire_locked_source() function).
* if fault_acquire_locked_source() fails with B_BUSY, the current cache is locked
again, and tested again for the page - as it might have been moved upwards to it
with the destruction of its former source.
* The cache delivering the page for vm_soft_fault() is now locked until the end;
it can no longer go away before having actually mapped the page into the area.
* This also fixes the issue where pages would get lost as vm_soft_fault() put the
page in the active list, no matter if its cache still existed.
* Also, we now keep a reference of to a cache in case a dummy page is inserted; this
makes again sure that it doesn't go away during the execution of vm_soft_fault()
(which could even add this page to the free list...).
* divided vm_soft_fault() into several smaller functions which should make it much
more readable.
* Added a "cache_chain" KDL command that dumps the whole chain until the bottom
when giving a pointer to a vm_cache as parameter.
* now usually call vm_cache_acquire_ref() before map_backing_store(), even though
it shouldn't be really needed (I added it for debugging purposes).
* Some minor cleanup.
* NOTE: a major problem still persists: when removing a vm_cache, it's possible
that some of its pages are still mapped, and there is currently no mechanism
to get rid of these mappings! I've added TODO comments into vm_cache.c where
appropriate.

tested on Qemu with aslcompiler.l => it takes more than 1m30s here, and shows a bottleneck in the kernel (the use of pipes)

Also prepare uname to return the build SVN revision number,
which will work only if I could figure out how to define it from Jamfile.
Or, better, in build/jam/BuildSetup.

huge deal but it doesn't make much sense to resize images during a slideshow.

The "lookup" option has been removed, there is now a "-p" for a physical address, and
"-v" for a virtual address.

a bit if you have enough memory (it's about 25% faster on a test case over here
with BeOS).

Ingo, could you review ? This check might also be needed at other places.

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.

* 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.

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.
