Can we now trivially reimplement xc_readconsolering in terms of this
function?

Should just be a case of replacing all the code between bounce_pre and
bounce_post with a call
        xc_readconsolering_buffer(xch, HYPERCALL_BUFFER_AS_ARG(buffer),
                                  pnr_chars, clear, incremental, pindex);
?

We should probably also deprecate the old one and at least have a vague
idea that we might eventually switch all the callers over (you don't
need to here though, unless you are super keen).

Ian.
