zbdd 77218e4a52 MDL-42993 auth: spaces removed from usernames by default only
Functionality by default does not change with this patch.
However spaces are no longer stripped when cleaning usernames IF
$CFG->extendedusernamechars has been set.

Also included 2 trim statements where small issues were found with reading
external usernames in that  were not filtered for trailing whitespaces.
