cgi/html: Only list root groups in navigation bar
cgi/html: Fix incomplete list of sub-groups in overview

The function for generating the group data is recursive,
however it reuses the same prepared statement. After the
first sub-group recursion, the original result of the
statement is gone.

Save the complete result set before we loop over it to
avoid this.
cgi/html: Fix PATH for fetched groups

PATH and PATHNAME for fetched groups is used to generate the
comparison URLs. Generate complete lists so we get correct
comparison URLs.

We should probably consider simplifying that section in the
overview template. Using the URL variable (as used for the
link to the group/domain view) should suffice.
cgi/html: Output NGROUPS variable as number of GROUPS

NGROUPS is used in some templates to check the validity of GROUPS.
cgi/html: Show comparison links only if there are 2 or more nodes

You cannot compare only 1 node.
templates: Move zoom.js reference after dynazoom form

This avoids running zoom.js before the form is available, resulting
in the form being empty and the image not loading.

p/debug: adding a huge multigraph plugin

Ganneff on IRC reported some performance issue with munin-update and huge
multigraph plugins. As it can happen on LUN-flooded hosts, with the stock
diskstats plugin, it has to be fixed.

Therefore this plugin will serve as a test one, to emulate those gigantic
plugins outputs.

Makefile: fix build on OSX

Override LANG things to make it build on OSX
Makefile: use $(AT) to enable V=1 in make
Makefile: --in-place isn't supported, option is -i

Note that -i takes a mandatory parameter, which is the backup extension.
We don't use that, so it's just empty.
dev_scripts: remove GNU readlink usage

Revert to old "cd && pwd" trick as it works reliably enough.
(hint, target is a directory, not a file)
Port the dev_scripts to OSX

This ports the various dev tools to OSX. It removes some GNU specifics,
and might be very useful on other *BSD as well.
Fix the chown correctly

Previous commit did just remove the chown in the Makefile. This is
obviously wrong.

Now we just override the $(CHOWN) to be /bin/true, which will do what is
epxected when using dev_script/install.
