RuleSet::AtomRuleMap should be private

This CL makes some functions on RuleSet private in order to hide the definition
of AtomRuleMap. These functions aren't used outside of this class.

Remove support for Mac OS X Leopard (10.5)

No need to support it in trunk. WebKit already dropped it in r149922.
Adjust usage of __MAC_OS_X_VERSION_MIN_REQUESTED and __MAC_OS_X_VERSION_MAX_ALLOWED
macros and remove dead code.

Get rid of multiple inheritence for SVGViewElement interface

Web IDL no longer supports multiple inheritence. As per the latest
specification SVGViewElement should only inherit from SVGElement.
'implements' statements are used for the rest. This patch refactors
the IDL files to match the latest specification:
http://www.w3.org/TR/SVG2/linking.html#InterfaceSVGViewElement

Note that there is a WebExposed change as SVGZoomAndPan used to be
exposed on the Window and it is not anymore. SVGZoomAndPan merely
supplements SVGViewElement and should not be exposed to JavaScript
according to the latest specification.
