utrace-cleanup branch

[Roland McGrath]

I've made a new branch, utrace-cleanup.
This forks from utrace-indirect and has:

26fefca utrace: sticky resume action
28b2774 utrace: remove ->stopped field

Those are the two changes we talked about during tangential ptrace discussions.

Again, I have compiled these but not tested a lick.  I'd just like to get
some feedback.  They both seem like happy clean-ups to me, making the code
smaller and simpler.

What do you think?


Thanks,
Roland
