Use case: I would like to bypass PHP for serving the RRD files and allow
the webserver (nginx) to compress it to reduce load on the Raspberry Pi.
I could go through all kinds of URL rewriting, but it is much easier to
set `$CONFIG['rrd_url'] = 'rrd/{file}';` instead and add a corresponding
location + alias directive to the nginx configuration.
This depends on https://github.com/manuelluis/jsrrdgraph/pull/17 to
avoid breaking on '='.

Previously, a command is built by string concatenation. Here, the
distinction between a value and multiple params got lost. Solve this
by using an array for shell arguments. As the escaping is now removed
from the `rrd_gen_graph` function, the canvas style needs to manually
add those quotes to make the JS code still work. That only supports
double-quotes, so hopefully nobody creates a name with a double quote
as that would break the fragile JS command line parser.
Separate the rrdtool options from the rrdtool graph command to make the
`$graph_type == 'canvas'` option work (it would otherwise not understand
the `rrdtool graph - -a PNG` option).
Merge the SVG and PNG cases as they are the same except for the
Content-Type header.
Fix a missing html escape in a debug style.

Set $CONFIG['percentile'] to a number and a XXth percentile line + legend
will be added to all network traffic (if_octets) graphs.

A couple of big changes here. A lot of logic moved to graph.php.
The PHP plugin files have been rewritten to JSON. In these JSON files
*everything* is optional. Also *NOT* having a JSON plugin file won't
block you from having a graph. The JSON will just make the graphs
prettier (by having a title, y-axis title, legend, colors, etc..).
The Collectd types.db file is parsed and used to determine RRD content.
When things are not defined in the JSON it will fallback to a default.

It's good to have an example, but it's a bit confusing having it enabled by
default.

Config setting $CONFIG['datasize'] can be set to bits or bytes to show graph
data in bits or bytes.

When running CGP in the root, the header didn't link to the overview page
because the href was empty.

When config.php was copied to config.inc.php it would result in a infinite
include loop.

Since I'm using a non standard installation of rrdtool, I always
have to define the --font options when colling the rrdtool binary.
I tried to implement this change in a general way to define locally
rrdtool options in the config.local.php.

Planned for collectd version 5.0 is to move the type instance of plugins
df and interface to the plugin instance (see source). From version 5.0 the
default is to group data from a type instance OR data source in one graph.
In case of version 4 there are only 2 plugins to exclude from this: df and
interface.

Via the UnixSock plugin of Collectd it is possible to send commands to the
Collectd daemon. One of the commands is the FLUSH command, which you can
use to let the daemon write cached data to the rrd files.
CGP uses the FLUSH command before generating a graph and before showing
the load information on the main page. In this case the information shown
via CGP is always up-to-date. Also when you have configured the RRDTool
plugin of Collectd with a CacheTimeout setting.
This commit includes code based on functions collectd_identifier and
collectd_flush from php-collection by Bruno Prémont.

These configuration options have been added:
- width
- heigth
- detail-width
- detail-heigth

CPG is designed to run out-of-the box. The local config is optional.

Collectd Graph Panel is a frontend for Collectd written in PHP.
The goal of CGP is to provide an easy-to-use frontend for Collectd,
starting with page that shows an overview of all the hosts you are
managing with Collectd.
In this initial import there is support for the plugins that are default
enabled in Collectd. The supported plugins are located in the plugin
directory.
