[PATCH 1/1] gdbserver: Reinstall software single-step breakpoints in resume_stopped_resumed_lwps

[Kevin Buettner]

I've pushed this commit, after having made a slight change to the new
test case.  Luis found that it ran slowly on his hardware, so, after
some testing, I made some adjustments so that it'll run faster.

I also added a Tested-By tag for Luis.
