OSS-Fuzz Issue 806: integer overflow in mtree_atol10

Rework the mtree_atol10 integer parser so it can parse
INT64_MIN without overflowing the intermediate value.

While here, make this function behave a little more predictably for
too-large input: It now always advances the pointer to the first
non-digit character.
