Patch to add LZW compression based on xpdf-3.04
This patch adds support for LZW compression using the code from xpdf-3.04.
xpdf had a psLZW flag in GlobalParams. I changed it to enableLZW in PSOutput.
In Stream.cc, xpdf used getBlock(buf, len) in LZWEncoder. I updated it to
doGetChars(len, buf).

I also added a few other small changes from xpdf-3.04.</pre>
