- The kernel stores the group IDs in the team structure. They are
correctly inherited on fork() and load_image_etc().
- Implemented getgroups() for real, i.e. it retrieves the groups
associated with the process.
- Implemented setgroups(), initgroups() and (the BSDish)
getgrouplist(). The latter two read the group information from the
"group database" /etc/group (if existing).
- Change the BIND port config, since we do have getgrouplist() now.
* The set-uid feature was broken when the path to the executable was
relative, since we used stat(), which, in the kernel, uses the kernel
IO context.
