iowatcher: iowatcher: support png2theora for videos
ffmpeg is not available on all distributions, so include Theora
as an option, via png2theora, if the output movie filename ends
in .ogg or .ogv

iowatcher: Fix path name handling when the trace files are in the current directory

iowatcher: Fix buffer overwrite issue
Current code allocates buffer for path based on strdup, which would let
the size of path equals to the size of blktrace_dest_dir. But the code
next that joins it with the filename of dump file, which would overwrite
the buffer, and triggered an issue like following:
$ ./iowatcher -t trace.dump -o trace.svg
Unable to find trace file ./trace.dumpY
^
Refactoring join_path a bit to fix this issue.

iowatcher: Improve xticks logic
Ticks on x axis used integral step and fixed number of ticks. That generates
wrong results e.g. for 13s long trace with 10 ticks... Allow the code to
somewhat alter the number of ticks and also use non-integral step.

iowatcher: Fix filtering of outliers from below
There are lots of trace actions which do not carry a sector with them (e.g.
plug, unplug, ...). Thus sector is 0 for them and that results in trimming
of outliers from below never working. Fix the problem by accounting only
Queue events in the outlier statistics.
