Remove configuration preprocessor symbols 'THREAD'

and 'THREAD_SAFE_CLIENT'.
  
As of MySQL 5.5, we no longer support non-threaded
builds.   This patch removes all references to the
obsolete THREAD and THREAD_SAFE_CLIENT preprocessor
symbols.  These were used to distinguish between
threaded and non-threaded builds.

- *
- *      It is currently unclear whether the prefered behavior is

- *      The latter behavior would be desirable for collecting
- *      accumulated runtime history over a number of separate
- *      runs.  It might take some changes to the analyzer program
- *      though, and the notes that Binayak sent with the profiling
- *      diffs indicated that append was the normal mode, but this
- *      does not appear to agree with the actual code. I haven't
- *      investigated at this time [fnf; 24-Jul-87].
