* refactor: discovery protocols re-write
extract more code to make it easier to read
use snmpwalk_group
walk lldpRemTable instead of lldpRemoteSystemsData
Optimize discover_device to reduce dns lookups of bad dns names
Make discovery_by_ip behavior consistent between cdp and lldp
move can_skip_discovery to discovery functions
Tested lldp, cdp, and ospf.
* always discover links even if the remote device isn't in system
Fix discover_link always updating

* remove orphaned links
* update db_schema.yaml
* Refactor remove use of pear Net_IPv4 and Net_IPv6
Caution, I added tests to test the functionality of the new functions, but I'm not 100% certain the replaced usages match 100%. Please test.
Left usage in generate-iplist.php because I'm not sure the use of that script, so I didn't want to implement additional functionality to support it.
Add support for ipv6 fo ipInNetwork() function
Add phpdocs to functions
Remove accidental inclusion
Use binary operations instead of string for networKFromIp()
Tidy up binary operations in ipInNetwork()
tidy parsing cidr network
Change to a class based implementation.
Update phpdocs.
Fully catch exceptions for hex parsing.
Fix mistake.
support older phpunit versions
Fix php shifting to negative with php 5
* Fix graph authorization. Uncaught exception and checking an ipv4 against an ipv6 network == fail.
* Also remove colons from hex strings.
* Fix typo in bgp polling
Two passes of removing invalid characters from hex strings. (That way we don't mangle valid IPs)
