Original pointer alpha update message is too specific for x11 implementation. It doesn't allow pointer alpha mask with both 'xor' color and 'and' mask, e.g.: the 'edit' pointer in windows text box. 1. Move shadow_client_convert_alpha_pointer_data to x11 implementation as it is specific for x11. 2. Update message definition to be more generic: to accept 'xor/and' mask directly. Implementation of subsystem can implement its own way to convert pointer mask data. 3. Fixed fault handling to free the resource allocated.
