(perl #129000) create a safer utf8_hop()
Unlike utf8_hop(), utf8_hop_safe() won't navigate before the
beginning or after the end of the supplied buffer.
The original version of this put all of the logic into
utf8_hop_safe(), but in many cases a caller specifically
needs to go forward or backward, and supplying the other limit
made the function less usable, so I split the function
into forward and backward cases.
This split may also make inlining these functions more efficient
or more likely.
