net: introduce EXPORT_IPV6_MOD() and EXPORT_IPV6_MOD_GPL() 



We have many EXPORT_SYMBOL(x) in networking tree because IPv6
can be built as a module.

CONFIG_IPV6=y is becoming the norm.

Define a EXPORT_IPV6_MOD(x) which only exports x
for modular IPv6.

Same principle applies to EXPORT_IPV6_MOD_GPL()
