This patch adds support for running intel_gpu_top to profile specific
commands. The required command will be carried out in separate process,
and main intel_gpu_top will leave when the child process will exit.

This patch adds support for non-interactive mode, invoked by running with
'-o output' switch. In this case, no interactive output is being
performed, but the execution statistics are being saved into the output
file.
The output file is generated in both human and gnuplot-readable format.
Unlike interactive mode, where non-supported pipes and non-active
registers are skipped, the content of such pipes and registers is recorded
into the log file to simplify parsing and standardize the list of columns.
Also, unlike interactive mode, the registers are not sorted according to
the usage - this way, their variation over time can be analysed offline.

This patch initializes the last_stats[] for registers prior to starting
the monitoring itself. This way, the first measure will already contain
the difference from the previous value instead of non-initialized value.

This patch adds support for getopt, and adds two default parameters to it:
-h to show usage notes; and -s to allow user to define number of samples
to acquire per second.
Manpage documentation is also adjusted accordingly.
