Jim Patterson 01544c52f8 wall: add --group option 
The wall command on AIX supports a "-g" option to limit the message
to a group of users by gid.  Add compatibility to the Linux version.

Thanks to Sami Kerola <kerolasa@iki.fi> for an initial skeleton
implementation.

[kzak@redhat.com: - rename max to ngroups
                  - add free_group_workspace()
                  - some cosmetic changes]
