Now that we have a long-sized tick counter, we can migrate to using properly typed timeout parameters in various bits of the LinuxKPI. This fixes a subtle incompatibility that is otherwise difficult to paper over and leads to bugs when ticks values are sign-extended. - Introduce a "jiffies" symbol in subr_ticks.S, declared only in the LinuxKPI as an unsigned long. - Remove all references to "ticks" from the LinuxKPI. - Convert interfaces to match Linux's type signatures where it makes sense.
