[LINUX5250] fix scs2pdf.c to handle very large files

[James Rich <james@xxxxxxxxxxx>]

I think I forgot to post this patch to scs2pdf.c to handle very large
spooled files (like around 18,000 pages).  A quick look at the archives
shows that I didn't post this.  The changes are against current cvs (head
- not 0.16).  Patch follows.

+- Fixed scs2pdf.c to handle very large spooled files.  We were overflowing
+    an array (textobjects).  This is now changed to be an expanding array.
+    Also changed some integers to unsigned long that counted things like
+    the number of pages.
