Fix json serialization for {x | -1 < x < 1} ( fixes #308 )
...
JSON serialization was preserving the value as presented, but JSON
doesn't accept decimal values without a 0 before the decimal point.

JSON::serialize -> unparse
...
Unparse is admittedly strange, but I'd rather be strange and
consistent, and everything else in the qpdf library uses unparse to
serialize. (If you're reading this, the convention of using "unparse"
comes from the "clu" programming language.)

Pl_DCT: Use custom source and destination managers ( fixes #153 )
...
Avoid calling jpeg_mem_src and jpeg_mem_dest. The custom destination
manager writes to the pipeline in smaller chunks to avoid having the
whole image in memory at once. The source manager works directly with
the Buffer object. Using customer managers avoids use of memory source
and destination managers, which are not present in older versions of
libjpeg still in use by some Linux distributions.
