netfilter: use a linked list of loggers
This patch modifies nf_log to use a linked list of loggers for each protocol. This list of loggers is read and write protected with a mutex. This patch separates registration and binding. To be used as logging module, a module has to register calling nf_log_register() and to bind to a protocol it has to call nf_log_bind_pf(). This patch also converts the logging modules to the new API. For nfnetlink_log, it simply switchs call to register functions to call to bind function and adds a call to nf_log_register() during init. For other modules, it just remove a const flag from the logger structure and replace it with a __read_mostly.
