handle out of range value for COLUMNS / LINES (#21968)

Browse Source 
* handle out of range value for `COLUMNS` / `LINES`

Querying terminal size may fail with a `ValueError` if size is too big.
Return highest possible value instead. Note that `ValueError` is also
reported on underflow (negative size) but that is out of POSIX specs.

* `parseSaturatedNatural`
