Summary: Object Streams for PDF-1.5

Initial Comment:
Rough early patch, work in progress, produces PDF-1.5
object streams and cross reference streams. With the
patch, and enabled by \pdfminorversion=5, and with
luck, pdfetex produces e. g. from its WEB source a PDF
file with size 5.97 MByte instead of 11.2 MByte without
object streams.

Regards, Hartmut

Patch update. Object stream writing is now controlled by
primitive \pdfobjcompresslevel = 0...3 (/pdfobjectstreams
primitive removed). 0 = no object streams at all, 1 =
compress objects excluding the ones from embedded PDF files
(for handling of problematic PDF files) and /Info dictionary
(for legibility), 2 = also compress objects from embedded
PDF files, but leave /Info uncompressed, 3 = compress
everything.

Testing welcome.

Regards, Hartmut
