The name Olson was misspelled as Olsen in the public api of QTimeZone
which is needed to be fixed before first public release in 5.2 would
freeze the api and prevent it being fixed. It has been decided that
renaming as IANA ID would be more future-proof.
Fixes to the private code will be done separately to keep this patch
against release branch to the minimum required.
