Fix for bug 6050753.

The method:

TypedArray: getLayoutDimension(int, String)

throws an undocumented exception when either the width and/or height
attributes are undefined.

See the bug report above for reasons why this was deemed unhelpful both
in the tools area and to developers in general.

Fix by:

1. Documenting the conditions under which the method raises an exception.
2. Deprecating the method, advising callers to supply a default instead.

Additionally, redefine the:

ViewGroup: setBaseAttributes(TypedArray, int, int);

methods to provide the appropriate defaults in ViewGroup subclasses as
advised above.

For the platform layouts the default value is WRAP_CONTENT (and is
defined in the ViewGroup.LayoutParams class). The special cases
are accomodated in LayoutParams subclasses in the following cases:

Subclass				width		height

FrameLayout.LayoutParams: 		MATCH_PARENT, 	MATCH_PARENT
TableLayout.LayoutParams: 		MATCH_PARENT, 	WRAP_CONTENT
TableRow.LayoutParams: 			MATCH_PARENT, 	WRAP_CONTENT
