[Devel] accessor for traces array

[Masatake YAMATO]

Currently, a program using FT2 cannot know what kind of traces are
existing. How do you think export the names of traces?
I'm using the attached patch for exporting the names of traces from
FT2. As the result I can provide a GUI to control the traces.
See the attached png image. In the image left column stands for
the name of traces; and right column stands for the trace level.
