DejaGnu merge

[Andrew Cagney]

\
> `Adopt a policy of only using well-tested dejagnu releases'?  The current src/dejagnu is based on a release + a set of specific up-stream approved patches (namely KFAIL).  The expectation, consistent with readline, is that at iregular intervals, a new release would be merged in allowing the number of upstream patches to be redused.

PS, For those that are wondering.  Ben is involved in some very recent 
upstream dejagnu development activities.  See:
