Bug 701949: Add 'omitEOD' flag to RLE compressor and use for PXL.

It turns out that some printers (Samsung ML-2250 and Canon
ImageRunner iRC2380i at least) object to the EOD byte appearing
in RLE data in PXL streams.

Ken kindly checked the PXL spec for me, and found that: "The PXL
spec does say a control code of -128 is ignored and not included
in the decompressed data and the byte following a control byte
of 128 (I assume they mean -128 here) is treated as the next
control byte. And PCL only uses RLE data for images, so they do
know how much data they expect."

Thus, the conclusion we reached is that PCL/PXL don't need
(indeed, really does not want) the EOD byte.

The Postscript spec clearly defines the EOD byte though. Rather
than break the streams for postscript, we introduce a flag
'omitEOD' that can be set for the encoder when we want to produce
a stream for use with PCL/PXL.
