QPDFJob increment: basic QPDFJob structure Move most of the methods called from qpdf.cc after argument parsing into QPDFJob. In this increment, enough QPDFJob API has been added to handle the branch of QPDFJob::run() that creates output with an appropriate division between qpdf.cc and QPDFJob. There are temporary bits of code to enable everything to compile and pass the test suite, including some duplication and hard-coded values.
