A much better PDF generator than yesterday

Whew!  I got stuff working a lot better.  scs2pdf doesn't run off the
bottom of the page anymore, and properly supports multi-page output.  It
still prints off the right edge of the page if the output is wider than
8.5 in.

Scott, can you try this new version and tell me if you still have spacing
problems?

I also updated the Makefile.am so everything works with autoconf.  Just
./configure, make, make install and you are all set.

Here is what remains to be done:

1. Handle page size.  We could either just use a small font all the time
(obviously not a very good idea) or we need to figure out how to change
fonts.  Even if we make the PDF use landscape, which I don't know how to
do yet, we will still have to handle really wide output, like 198 columns.

2. Handle different fonts.  We don't need to use 10-point Courier for
everything if we don't want to.  This isn't so important as #1.

3. Handle margin size.  It is now hard-coded to 1/2 inch top and left
margin.  This ought to be changeable.

4. Handle page breaks.  Right now it just breaks after so many lines have
been printed.  I don't know the SCS print stream too well so I don't know
what to check for regarding page breaks.  Maybe the SCS_FF macro is the
page break?  From Mike's code it appears so.  If someone can confirm this
I can make it so.
