* Parse the *src string and store a scaling unit into *dst.

* If the string doesn't specify the unit, use the default.

* If no default is specified, fail.

* Return 2 on complete success, 1 when a conversion was done,

* Return a pointer to the byte after the last byte used,

* but there was trailing garbage, and 0 on total failure.

* or NULL on total failure.
