GhostPDF + GS - improve error handling
Arising from Bug #705784, if we hadn't built the PDF interpreter we
would get typecheck errors which were somewhat misleading as to the
source of the problem.
This commit tidies up the error handling in the area of .PDFInit so
that we not only detect the problem there but give a warning that it
occurred.
In addition, add a means to detect if the PDF interpreter is built in
before we stat trying to process a PDF file and, if it is not, give
a sensible error message.
Tested with BUILD_PDF 0 and with NEWPDF true and false.
