[PATCH 0/1] gdbserver: Reinstall software single-step breakpoints in resume_stopped_resumed_lwps

[Kevin Buettner <kevinb@redhat.com>]

This patch fixes a problem with software single-stepping in gdbserver.
See the 1/1 patch for the details.

The fix proper is based on the work of Zhiyong Yan, who I've credited
with a Co-Authored-By tag in the 1/1 patch.  The test case was also
partly Zhiyong's work since I adapted the C file from the reproducer
in the bug that was filed for this problem.

Zhiyong, please check to make sure that this revised change to
gdbserver/linux-low.c still fixes the bug on your board.

I've added Simon as a CC since the .exp file for the new test is based
on gdb.threads/next-fork-other-thread.exp, which he authored.  Also,
from my reading of the commit log for that test, I gather that Simon
has looked at a related problem in the past.
