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.

Put a specific comment marker next to every piece of code that MSVC

functions that Microsoft considers insecure or deprecated. This

of them are actually incorrect or insecure as used in qpdf. The
comment marker makes them easier to find so they can be fixed in
subsequent commits.
