Make archiving hooks protected in layout classes.

Furthermore,
* remove a stray blank line in Layout.cpp
* make BLayoutItem::SetLayout() private, as it should have been

Override a bunch of methods in layout related classes for FBC stability.

* Especially made sure to override archiving methods, since these are called rarely, so the cost is very minimal
* Otherwise, the closer a class is to a base class, the more likely I was to give it all the overrides.

By convention, Perform() methods are public, make this true for BLayout.

Forbid copying and assignment in layout classes.
Specifically in:
* BAbstractLayout
* BAbstractLayoutItem
* BGridLayout
* BGridView
* BGroupLayout
* BGroupView
* BLayout
* BSplitView
* BTwoDimensionalLayout

Add FBC padding to all (I think..) of the visible Layout related classes.

Add Perform() methods to all the layout-related classes that needed them.

Revirtualize BLayout::Relayout(), since it is in fact inherited from BLayoutItem and virtual anyway.

Also add a comment to make this obvious.

Now that child classes aren't overriding the various InvalidateLayout() methods, we can take advantage of some guarantees to simplify/clean/optimize the layout invalidation propagation mechanisms!

Add BLayoutItem::LayoutInvalidated() hook. Leave BLayoutItem::InvalidateLayout() (and therefore BLayout::InvalidateLayout()) virtual. This is needed to let BLayout override it for invalidation propagations.

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.

De-virtualize BLayout::Relayout(). I think this was virtual only by accident.

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

User BView's layout item tracking functionality to simplify and optimize some methods in BLayout and BView.
Delete BLayout::RemoveViewRecursive() as it is no longer needed.
Add a few TODO's.

Also made LayoutContext() const.

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.

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 (minor changes by myself) related to the new archiving
features:
* Some cosmetic adjustments of the API, like using references instead of
pointers, argument order, method names, etc.
* Added convenience template methods for archiving and unarchiving to BArchiver
and BUnarchiver.
* BUnarchiver (respectively the private BUnarchiveManager) explicitly deals with
object ownership, now. This is necessary since an error while unarchiving
could leave an already unarchived object without owning object, which would
result in it being leaked. The BUnarchiver::{Get,Find}Object() methods do now
have an optional parameter to specify whether object ownership shall be
transferred.
* Fixed incorrect header guard in headers/private/binary_compatibility/Global.h.

Finished unifying the Interface Kit headers:
* Fixed copyrights (puncuation and capitalization, removed authors from
headers)
* Updated indentation style
* Unified pointer/reference style
* Re-ordered some methods for better grouping where it could be done
(abd adopted source accordingly)
* Small coding style fixes here and there

No functional change intended.
