* Source/cmake/OptionsMac.cmake:
* Source/cmake/WebKitFeatures.cmake:
Defined and enabled some more features needed on Mac.
* Source/cmake/WebKitMacros.cmake:
Objective C bindings need special changes when generating:
Some of the bindings do not generate a .mm file but the header is needed.
Some of the bindings do generate a .mm file that doesn't compile but the header is needed.
In order to handle these cases, it is necessary to change the GENERATE_BINDINGS macro just for ObjC.

Source/JavaScriptCore:

* CMakeLists.txt:
Make forwarding headers for the replay subdirectory.
* PlatformMac.cmake:
Make forwarding headers for the generated inspector headers.
They should eventually either be packaged correctly with JavaScriptCore headers and included correctly.

Source/WebCore:

* CMakeLists.txt:
Added some more files.
* PlatformMac.cmake:
Added more files and listed the strange ObjC bindings.
* contentextensions/DFACombiner.cpp:
* contentextensions/DFACombiner.h:
Added preprocessor protection.
* platform/FileSystem.h:
Include utility.  It's needed to compile the different configurations.
* platform/ScrollAnimator.cpp:
ScrollAnimator is an abstract class on Mac.  Don't compile it.
* platform/graphics/ca/cocoa/PlatformCALayerCocoa.mm:
FontAntialiasingStateSaver.h is only used on iOS.
* rendering/RenderThemeMac.mm:
config.h needs to be outside the #if !PLATFORM(IOS) to compile correctly without precompiled headers.

Source/WebKit:

* CMakeLists.txt:
* PlatformMac.cmake:
Added more sources, make non-c99 sources compile as objc++
* PlatformWin.cmake:
Moved WebCoreTestSupport sources and includes to CMakeLists.txt to share.

Source/WebKit/mac:

* WebView/WebPDFDocumentExtras.mm:
(appendValuesInPDFNameSubtreeToVector):
* WebView/WebPDFView.mm:
Removed cmake include quirks that are not needed when we include things correctly from Quartz.framework/Frameworks.

Source/WebKit2:

* PlatformMac.cmake:
Added some more sources.
