Extend gnt-debug with more debugging options

This patch extends gnt-debug to be able to submit multiple copies of the
input jobs and job contents, in order to simplify testing. It also adds
a timing mode, and splits the execution into separate submit and
execution stages (for timing purposes).

The <option>verbose</option> option will job the job IDs of
the submitted jobs and the progress in waiting for the jobs;
the <option>timing-stats</option> option will show some
overall statistics with the number of total opcodes and jobs
submitted, and time time for each stage (submit, exec, total).
The <option>job-repeat</option> and <option>op-repeat</option>
options allow to submit multiple copies of the passed
arguments; the job repeat will cause N copies of each job
(input file) to be submitted (equivalent to passing the
arguments N times) while the op repeat will cause each job to
contain multiple copies of the opcodes (equivalent to each
file containing N copies of the opcodes).
