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.
