Gnuplot interface refactoring

[Teemu Ikonen]

Hi all,

Here's the final version of the patch which splits the gnuplot code from the
parser to a separate file. All the M*lab compatible plotting commands can
now be easily overridden with m-files. Functions handling temporary files
are moved from pt-plot.* to file-io.*, which makes a one-line fix to
octave-forge necessary.

The patch is attached as a tar+gzipped arch changeset, which means that it's
just a directory containing the patches, new and deleted files and metadata
changes. For more info, see:
http://www.gnu.org/software/gnu-arch/tutorial/changeset-format.html

In principle, it can be applied to a source tree by just issuing a 
'tla dopatch' command, but this will also bring some arch cruft (id-files)
with it. A changelog entry is attached separately.
