First draft of cvs 2 svn conversion

Put the shell script in a directory by itself.  You'll need
to have rcs and subversion installed.  At the end of the
run, it runs svnserve on port 1234.  I suggest using
TortoiseSVN repo browser from a windows box pointed at 

  svn://linuxbox:1234/

When we do the changeover, the CVS repository will still be
maintained by SourceForge so there isn't that much point
in also bringing all the tags etc over, or a lot of other
historical baggage (eg the modified version of paramiko that
was used for a while).

I still need to remove more gunk, particularly items that
got moved from one place to another (eg webhelp).  That
involves going through the Attics and seeing what isn't
used any more.

Something also worth considering is moving all the phone
code (com_*, p_*) to a subdirectory.  This migration may
be the best time to pretend that things were always done
that way :-)
