Eric Dumazet d268c1f5cf net: add CONFIG_DEBUG_NET 
This config option enables network debugging checks.

This patch adds DEBUG_NET_WARN_ON_ONCE(cond)
Note that this is not a replacement for WARN_ON_ONCE(cond)
as (cond) is not evaluated if CONFIG_DEBUG_NET is not set.

Eric Dumazet 5b87be9e49 net: add include/net/net_debug.h 
Remove from include/linux/netdevice.h helpers
that send debug/info/warnings to syslog.

We plan adding more helpers in following patches.

v2: added two includes, and 'struct net_device' forward declaration
    to avoid compile errors (kernel bots)
