Under ARC (Automatic Reference Counting), assigning to an Objective-C pointer has different semantics than assigning to a void* pointer. This makes it dangerous to treat the same memory address as an Objective-C pointer in some cases and as a "regular C pointer" in other cases. This change removes the conditional type defines and instead uses void* everywhere. Explicit type casting in combination with ARC annotations makes it safe to get typed Objective-C pointers from the void* pointers. This change enables ARC by default in the CEF binary distribution CMake configuration for the cefclient and cefsimple sample applications. It can be disabled by adding `-DOPTION_USE_ARC=Off` to the CMake command line. ARC is not supported when building Chromium due to the substantial number of changes that would be required in the Chromium code base.
