fix integer overflow bugs in *stosbt

68f57679d660 Fixed another class of integer overflows, but introduced a
boundary condition for 2-4s in ns conversion, 2-~4000s in us conversions
and 2-~4,000,000s in ms conversions. This was because we bogusly used
SBT_1S for the notion of 1 second, instead of the appropriate power of
10. To fix, just use the appropriate power of 10, which avoids these
overflows.

This caused some sleeps in ZFS to be on the order of an hour.

Fix overflow errors in sbttous and sbttoms

Both of these functions would overflow for very large inputs.  Add tests
for them.  Also, add tests for the inverse functions, *stosbt, whose
overflow errors were fixed by 4c30b9ecd47.
