LibLine: Allow the embedder to optionally handle pasted data itself

Browse source 
If the 'on_paste' callback is set, LibLine will buffer the pasted data
and pass it over to the embedder to use as it pleases; in practice, this
means that the users of LibLine can now escape or otherwise handle
pasted data without the incremental codepoint-by-codepoint buildup.
