Remove enum elaborated type specifier

...from orientation params. Elaborated type specifiers are not needed
for C++ code and removing them makes doxygen happy. Verified working
on both gcc2h and gcc4h builds.

Adjust method naming.

Add {Get,Set}ItemVisible() accessors and setters.

Add GetCollapsible() accessor to BSplitView/Layout.

Devirtualize BLayout::InvalidateLayout(), add a protected hook BLayout::DoLayout(). This will allow for much better control over the propagation of layout invalidations, and therefore cleaner, more optimal code.

Rename BLayout::DerivedLayoutItems() to DoLayout(), which is consistent with BView::DoLayout(). Also adjusted child classes and documentation.

Big change deriving BLayout from BLayoutItem, and allowing viewless BLayouts.
a few highlights:
* BLayout now derives publicly from BLayoutItem
* Added BAbstractLayout class, which our layouts now derive from
* updated layout builders to avoid creating views when they don't need to
* updated layout classes
* updated AboutSystem to fix a little regression
* more details on #6407
* please tell me about any regressions, I've tried to find them all, but some
may have slipped by.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@38207 a95241bf-73f2-0310-859d-f6bbb57e9c96

Update BLayout::ItemAdded() and BLayout::ItemRemoved() to take an int32 index parameter, and ItemAdded() to return a bool indicating success or failure. Update BLayout::AddItem() to take the result of ItemAdded() into account. Also update BLayout::AllUnarchived() to take this into account. In either situation, if ItemAdded() returns false, the item does not get added to the layout. Removed various TODOs about code that could be removed once this change was made. In BSplitLayout, an item's LayoutData was lazy-initialized, but would always be created during ItemAdded(). Now we create the LayoutData explicitly, so that we can catch failed memory allocations. Closes #5524.

Patch by Alex Wilson:
* Added archiving/unarchiving support.
* Coding style cleanup (some more by myself).


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@37548 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Made BTwoDimensionalLayout and BSplitLayout::GetInsets() const.
* Give access to BSplitLayout::SetInsets() and GetInsets() from BSplitView.
* Give access to BSplitView::SetInsets() from BSplitLayoutBuilder and
LayoutBuilder.
* Some automatic white-space cleanup.

* Added BSplitView drawing code to ControlLook.
* BSplitView uses ControlLook to draw itself.
* Small refactoring in SplitLayout to implement IsAboveSplitter(BPoint).
* BSplitView updates the view cursor when the mouse is above a splitter.
* Standard splitter size is now 6 pixels, which is a bit easer to hit.

Removed the BSize(const BRect&) constructor and added BRect::Size()
instead. Also added a BRect(BPoint, BSize) constructor.
