Eugene Grosbein 9772e81551 MFC r347439 by markj: Atomically update the global gMsgId in libnetgraph.
Otherwise concurrently running threads may inadvertently use the same
token for different messages.

Preserve the behaviour of disallowing negative message tokens, but allow
a message token value of zero since this simplifies the code a bit and
tokens are documented to be non-negative.
