Subject: [pp] [ide] Minor cleanups in pp code.

- We avoid unnecessary use of Pp -> string conversion functions.
  and the creation of intermediate buffers on logging.

- We rename local functions that share the name with the Coq stdlib,
  this is usually dangerous as if the normal function is removed, code
  may pick up the one in the stdlib, with different semantics.
