package/readline: bump to version 8.0
- Remove first patch (already in version) and so remove
READLINE_AUTOCONF as configure.ac is not patched anymore
- Use the new --disable-install-examples option and remove
READLINE_PURGE_EXAMPLES
- Remove READLINE_INSTALL_PC_FILE as readline.pc is installed since:
http://git.savannah.gnu.org/cgit/readline.git/commit/Makefile.in?id=
8e6ccd0373d77b86ed37a9a7d232ccfea3d6670c
- Remove READLINE_INSTALL_FIXUPS_SHARED (libraries are installed with
correct rights)
- Add hash for license file
