Reorganize in6_tmpaddrtimer stuffs
- Move the related functions to where in6_tmpaddrtimer_ch exists
- Hide global variable in6_tmpaddrtimer_ch
- Rename ip6_init2 to in6_tmpaddrtimer_init
- Reduce callers of callout_reset
- Use callout_schedule

Validate ip6_temp_preferred_lifetime (net.inet6.ip6.temppltime) on a change
ip6_temp_preferred_lifetime is used to calculate an interval period to
regenerate temporary addresse by
  TEMP_PREFERRED_LIFETIME - REGEN_ADVANCE - DESYNC_FACTOR
as per RFC 3041 3.5.  So it must be greater than (REGEN_ADVANCE +
DESYNC_FACTOR), otherwise it will be negative and go wrong, for example
KASSERT(to_ticks >= 0) in callout_schedule_locked fails.

tests: add tests for the validateion of net.inet6.ip6.temppltime

in6: reset the temporary address timer on a change of the interval period
