QPDFJob increment: get rid of exit, handle verbose
Remove all calls to exit() from QPDFJob. Handle code that runs in verbose mode to enable it to make use of output streams and message prefix (whoami) from QPDFJob. This removes temporarily duplicated exit code logic and most access to whoami/std::cout outside of QPDFJob proper.
