lib: add ASCII fast path to getStringWidth()

2019-09-03T04:02:34+00:00

A lot of strings that are going to be passed to `getStringWidth()`
are ASCII strings, for which the calculation is rather easy and
calling into C++ can be skipped.

console: use getStringWidth() for character width calculation

2019-09-02T06:13:58+00:00

This is more accurate for displayed full-width characters
(e.g. CJK ones) and makes the calculations match the ones we
use in the readline module.
