Further fixes for per-tablespace options patch.
Add missing varlena header to TableSpaceOpts structure. And, per
Tom Lane, instead of calling tablespace_reloptions in CacheMemoryContext,
call it in the caller's memory context and copy the value over
afterwards, to reduce the chances of a session-lifetime memory leak.
