[Devel] [RFC] NETNS_REFCNT_DEBUG define

[Stanislav Kinsburskiy]

Hello gentlemen,

There was NETNS_REFCNT_DEBUG debug introduced in past to track down 
situations, when network namespace is being hold (not referenced; 
another ref count is used) by various objects, so, on net namespace 
release such situations with leaked network objects can be reported.
We don't have this option enabled.
And thus there are two options: either enable it, or clean out all the 
references to it's functions, to they won't obfuscate the reader.
I personally would prefer the former.
