netfilter: nf_log: prepare net namespace support for loggers
This patch adds netns support to nf_log and it prepares netns
support for existing loggers. It is composed of four major
changes.
1) nf_log_register has been split to two functions: nf_log_register
and nf_log_set. The new nf_log_register is used to globally
register the nf_logger and nf_log_set is used for enabling
pernet support from nf_loggers.
Per netns is not yet complete after this patch, it comes in
separate follow up patches.
2) Add net as a parameter of nf_log_bind_pf. Per netns is not
yet complete after this patch, it only allows to bind the
nf_logger to the protocol family from init_net and it skips
other cases.
3) Adapt all nf_log_packet callers to pass netns as parameter.
After this patch, this function only works for init_net.
4) Make the sysctl net/netfilter/nf_log pernet.
