Refactor ncClipboard::GetData() for better readability, add nsClipboard::SetTransferableData() to send clipboard data to nsITransferable. According to Gtk people [1] we can't mix free()/g_free() and malloc()/g_malloc() calls. Existing nsClipboard code mixes that on some places which can lead to issued on glib built with specific flags (ENABLE_MEM_PROFILE or ENABLE_MEM_CHECK).
