Jay Berkenbilt fc74d67fab Correct handling of elf symbol versioning 
We were putting the value of LT_CURRENT in the versioned symbol map
instead of the soname major version, which was creating binary
incompatibility where none was present. Unfortunately, this bug is
already out there for qpdf 7.0.0, so we'll have to work around it for
now.

Jay Berkenbilt 569d74d36b Allow raw encryption key to be specified 
Add options to enable the raw encryption key to be directly shown or
specified. Thanks to Didier Stevens <didier.stevens@gmail.com> for the
idea and contribution of one implementation of this idea.

Jay Berkenbilt 6299c64cf3 Use correct link directory order (fixes #158) 
Make sure to link from the source tree before linking from the system.
In many environments, this is necessary to allow a newly built qpdf to
link properly instead of trying to link or resolve libraries from an
older installed version.

Jay Berkenbilt be27d47bdc Use better error for getStreamData failure 
If the stream isn't filterable but we call getStreamData, throw a
regular exception instead of a logic error so that normal error
handling and reporting mechanisms will be used.

Jay Berkenbilt 40ecba4172 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.
