properly parse network interface names with colon on them

[ktsaou]

Summary

fixes #4536

This PR fixes 2 bugs:

1. Network interface names may have a colon (:) in them. Netdata was incorrectly parsing these network interface names (: was assumed to be a separator).

   The effect of this was twofold:

   • the collected values was totally wrong (all values were shifted).
   • when interfaces sharing the same prefix, the same chart was updated multiple times per iteration, resulting in totally crazy values.

2. Families that had : in them, resulted in DOM element IDs with : in them. This crashed jquery.

This PR fixed them both.

@gmosx you have placed the NETDATA.name2id() function in compatibility.js which I think is not something about compatibility. We generally need this to properly convert strings to DOM element IDs.

@ktsaou OK, I will move it to utils.js.
