HEADS UP: Rebasing to Readline-7.0 in rawhide

[Siteshwar Vashisht]

Hello,

Readline-7.0 was released few months ago and I have rebased it in rawhide to version 7.0.
I have created a compatibility package compat-readline6 to avoid breaking any existing
applications.

Update to readline-7.0 caused a build failure with gdb that was fixed by this commit [1].

I am providing abidiff report for the changes between readline-6.3 and readline-7.0 :

ELF SONAME changed
Functions changes summary: 2 Removed, 2 Changed (1 filtered out), 17 Added functions

I would be happy to help if any package maintainers need my help with updating to
readline-7.0.
