  A Fedora GDB bug got me looking at error handling relating to GDB's
clone handling, and thread-db thread adoption.

The first two patches are some refactoring in this area, and the third
patch changes and improves error handling so that GDB is better able
to track threads even if thread-db thread adoption fails.

Thanks,
Andrew
