Reject out-of-range numeric timezone specifications. In commit 631dc390f49909a5c8ebd6002cfb2bcee5415a9d, we started to handle simple numeric timezone offsets via the zic library instead of the old CTimeZone/HasCTZSet kluge. However, we overlooked the fact that the zic code will reject UTC offsets exceeding a week (which seems a bit arbitrary, but not because it's too tight ...). This led to possibly setting session_timezone to NULL, which results in crashes in most timezone-related operations as of 9.4, and crashes in a small number of places even before that. So check for NULL return from pg_tzset_offset() and report an appropriate error message. Per bug #11014 from Duncan Gillis.
Back-patch to all supported branches, like the previous patch. (Unfortunately, as of today that no longer includes 8.4.)
