Actually, I can't do this. The files in the library are licensed under
LGPL, but these files you added are all GPL.
There's a reason I separated them as such. I guess we may be able to
move things out of the files if they are properly authored. That is, if
I wrote them. Some code I took and used in trace-cmd came from GPL v2
code, so those must remain GPL v2.
