Date:           Wed Oct 16 07:40:40 UTC 2019

Modified Files:
        src/sys/netinet6: in6_ifattach.c in6_ifattach.h in6_var.h ip6_input.c

Log Message:
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
