net: Add net_ratelimited_function and net_<level>_ratelimited macros
__ratelimit() can be considered an inverted bool test because
it returns true when not ratelimited. Several tests in the
kernel tree use this __ratelimit() function incorrectly.
No net_ratelimit uses are incorrect currently though.
Most uses of net_ratelimit are to log something via printk or
pr_<level>.
In order to minimize the uses of net_ratelimit, and to start
standardizing the code style used for __ratelimit() and net_ratelimit(),
add a net_ratelimited_function() macro and net_<level>_ratelimited()
logging macros similar to pr_<level>_ratelimited that use the global
net_ratelimit instead of a static per call site "struct ratelimit_state".
