Review request for KDE Frameworks.


Repository: kcoreaddons


Description
-------

Fix KUser::groups() and KUser::groupNames() on UNIX

If available we use getgrouplist() which returns all group IDs.
Otherwise we fall back to using getgrent() and checking whether gr_mem
contains the user. For some reason gr_mem doesn't usally contain the
users primary gid, so we add the corresponding struct group for that gid
as well.
