Patrick Palka 5836a818ec Revert "Sync readline/ to version 7.0 alpha" 
This reverts commit b558ff043d.
This reverts commit 4a11f20659.

The initial import commit failed to retain local changes made to
readline's configure.in (and the commit message erroneously stated that
there were no local changes that needed to be reapplied).  Also the
import caused a couple of build errors and a scattering of testsuite
regressions throughout many arches.  It's probably better to start over
with this import, hopefully more carefully next time.
