This work-in-progress is more questions than answers.

- Common code in "procfs.c" (tested) and "inftarg.c"
It makes me wonder if the native inferior code should be re-arranged 
(has this come up before?).

- The new files "auxv.[hc]" for parsing the file.
Perhaphs it belongs in "procfs.c" but that gets me back to the first 
question - could the native inferior code be better structured?
