Implement a few changes needed to properly resolve PR#30924, as
discussed in the PR. - introduce sys/timevar.h to hold kernel-specific stuff relevant to sys/time.h. Ideally, timevar.h would contain all (or almost) of the #ifdef _KERNEL part of time.h, but that's a pretty big and tedious change to make. For now, it will contain only the prototypes I introduced when working on COMPAT_NETBSD32. - split copyinout_t into copyin_t and copyout_t, it makes prototypes more explicit about the meaning of a given argument. Suggested by yamt@. - move copyinout_t definition in sys/time.h to systm.h as copyin_t and copyout_t - make everything uses the new types and include the proper headers at the proper places.
