Hi Dave,

this series removes the kernel_setsockopt and kernel_getsockopt
functions, and instead switches their users to small functions that
implement setting (or in one case getting) a sockopt directly using
a normal kernel function call with type safety and all the other
benefits of not having a function call.

In some cases these functions seem pretty heavy handed as they do
a lock_sock even for just setting a single variable, but this mirrors
the real setsockopt implementation unlike a few drivers that just set
set the fields directly.

Hi Dave and other maintainers,

can you take a look at and potentially merge patches 1-30 while we
discuss the sctp refactoring?  It would get a nice headstart by removing
kernel_getsockopt and most kernel_setsockopt users, and for the next
follow on I wouldn't need to spam lots of lists with 30+ patches again.
