DejaGnu 1.4.4 release

[Michael Elizabeth Chastain]

Andrew asks the key questions:

My opinion:

Go for removal first.  Tell people that the sourceware versions of
Expect and Dejagnu are going away and they need to use the upstream
versions.  Provide doco for downloading and building Tcl+Expect+Dejagnu.
(I can do that part).

Wait a month.  If no one objects, then kill the sourceware versions
of Expect and Dejagnu.
