structure. They are properly inherited and updated on
fork(), load_image(), and exec().
* Implemented the get[e]{u,g}id(), set[[r]e]{u,g}id() family for real.
* getgroups() also calls the kernel now, but only returns the effective
group ID. Supplementary groups support is still missing.

* Extended it to support long format as well.
* Extended it to support ranges of widgets (I didn't find those in the standard,
but the FreeBSD and Linux drivers implement them, and my laptop even makes
use of them, too).

* _Alloc() can now preserve the original reference count, only _Clone()
still initializes it to 1. As Karsten pointed out, this is necessary to
preserve the "shareable" status of the private data.
* I hope that's finally it. What happened to our testing suite, anyway? :-)

back to front copies in Window for updates. When in an update session,
any back to front copies are turned off. When the update session ends,
the whole region is copied at once. This has two effects: For once, it
avoids a lot of unnecessary copies (for example, rendering text copied
the background and then the same area for the text again). But even more
effective, it changes the entire drawing of any Haiku app to be completely
flicker free. Provided it happens in the normal Invalidate()/Draw() cycle.
And of course all this only works for double buffering mode, ie VESA.
Potentially, I might have overlooked something, so that this patch could
result in some drawing glitches, but in my testing, I have seen none yet.

* Added a CopyToFront(BRegion) method which copies a complete region from
the drawing/back buffer to the front buffer.

* Got rid of class ObjFunctionSummand. Both the constraint summands and
the objective function summands are now stored using class Summand.
* Some method names are more BeOS compliant now: SetX instead of ChangeX.
* linprog test code now uses new AddConstraint methods.
* CalculateMinSize and CalculateMaxSize did not free the memory they
allocated.
* Removed inappropriate setter and getter methods.
* Memory allocated in class Constraint is freed now.
* Other small changes.

uncommented the meaty lines again. Added one or two more explaining
sentences.
* Created a concise UserBuildConfig.sample with very few comments and
only the most interesting (commented out) example lines for those
people who don't read the UserBuildConfig.ReadMe.
I hope everyone can live with this solution.

_ReplaceAtPositions(), and _DoCharacterEscape() (we don't need to preserve
it, though, as it must be 1).
* Factored out an _Alloc() method which is now always called when the private
data is allocated. It also takes care of correct initialization (and thus
fixes the above problem).
* This fix finally allows turning on reference counting again, thanks Karsten!
* Minor cleanup, renamed "oldAdr"/"newAdr" to "oldString", resp. "newString".

* _Realloc(), and _Detach[With]() may fail, but that wasn't accounted for
everywhere.
* The Append(), Prepend(), and Insert() char versions all caused their
backends to access invalid data (must use strncpy() instead of memcpy()
here).
* All Append(), Prepend(), and Insert() BString variants used an invalid
check, and would therefore just do nothing in certain situations like this
one:
BString a = "-";
BString b = a;
a.Append(b);

I didn't test the change, but the way the cursor is optionally copied into
the bitmap (which might now be not 32 bpp) looks very flexible.

copy constructors, effectively turning of references completely.
* Since that caused troubles (NetPositive now crashes when started), I
temporarily disabled references by letting _IsShareable() always return
false until the issue is resolved.
* _FreePrivateData() now sets the fPrivateData member to NULL, and is also
safe to be called when fPrivateData is NULL.
* Removed my comment about the threading problem in _Detach() and _DetachWith()
as that just couldn't happen.
* _Clone() must not use memcpy() as the string pointed to by "data" might not
be as long as "length".
* LockBuffer() now marks a string as unshareable.
* Minor cleanup.

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.

of the resolved ToDo, but could probably be made more efficient. Instead of
transfering the area, the area is cloned into the target teams' address space
and the original is deleted. This generates a new area_id for the transfered
area (as suggested by the ToDo). Updated syscall prototypes according to the
status_t to area_id return type change.

* It's still not thread-safe for all usage patterns, though, so we might want
to remove or disable it: if a string is shared between several threads, and
one of those starts to use a reference, all kinds of problems can happen.
