* refactor: Centralize MIB include directory specification
The default is now:
```
$config['mib_dir'].'/mibdirname:'.$config['mib_dir']
```
This means we exclude OS mibs and only use ours (we could prepend `+` if we want to include os mibs.
All snmp calls should only include the name of the subdirectory under the mibs directory.
* Remove d_echo from Proc
Fix snmpsim tests.
* Proc class
Encapsulate processes in a class, when they go out of scope, we can use the __destruct() process to make sure the process terminates.
* Fix rrdtool_last checks failing
* Don't close rrdtool in rrd_graph
Try to start rrdtool process if they haven't been started yet
Remove some extra debug output
* phpdocs added
several cleanups
should still be functioning the same
Only open one rrdtool process for graph.php
* Prepare for dual rrdtool processes
Disabled at this time
Split out rrdtool version checks into rrdtool_create_command()
Tests for rrdtool_create_command()
Fixes a few small issues.
* Enable dual process and remote rrd check/creation
* remove full path for remote commands
* Doc updates
minor fix to rrdtool_tune()
* Set up bootstrap for phpunit
Fix issues with FileExistsException
* Attempt to fix phpunit
* Fix classloader and bootstrap to use full paths only (not depending on $config)
* Fix phpunit tests, config.php does not exist.
* Implement an autoloader
When cleaning up classes for psr2, things got a bit unwieldy, so I implemented a class autoloader.
I created a PSR-0 compliant LibreNMS directory and moved all classes there that made sense.
Implemented LibreNMS\ClassLoader which supports adding manual class mappings
This reduces the file includes needed and only loads classes when needed.
* Add teh autoloader to graph.php
* Add a small bit of docs
Fix incomplete class in includes/discovery/functions.inc.php
