For each tunable declaration, we create a zfs_tunable_t with its
details, and then a pointer to it in the 'zfs_tunables' ELF section,
that we can access later with a little support from the linker.

mod.h only exists to include the platform-specific mod_os.h, so we can
get rid of it and just call the platform header mod.h.
Then, create a libspl mod.h, and move the relevant items to it so we can
start building on it.
