Import readline 7.0 (patch 5)
This imports readline 7.0 (up to patch 5) while preserving all gdb-local changes. This was done by checking out the readline git repository, making a branch based on the gdb baseline revision, applying the gdb changes to that branch, and then merging from readline 7. readline/ChangeLog.gdb 2019-08-12 Tom Tromey <tom@tromey.com> * Imported readline 7.0 patch 5.
