PFS autosizing relies on table_definition_cache, table_open_cache,
max_connections, open_files_limit.

The only options that is autosized prior to PFS autosizing was
table_defintion_cache. Even this option was autosized incorrectly.

So I didn't break it, it was broken even prior to this patch. In 5.7 all these
options are marked EARLY and are autosized before PFS autosizing.

Sergey
