GetClipboardText() calls gtk_clipboard_request_text() to request text clipboard data from Gtk+
and leave Gtk+ to do clipboard text format conversions. Also unify data getting code for text/data/targets.

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).
