Various functions in tree-pretty-print.c take a param
pretty_printer *buffer
and there's also a static pretty_printer *buffer;
Additionally, pretty_printer instances are not buffers; they
*contain* buffers (inasmuch as they have a field "buffer").
This patch renames such params from "buffer" to "pp", and the static
"buffer" to "tree_pp" to make it easier to tell what we're dealing
with (a param, a file-static, or a buffer).
