Add tuning advise for os_cache_dirty_max, os_cache_max.
Try and group WT cache options together, add more discussion of compression.
Don't drop core if an open fails, it's just a distraction from debugging.
os_cache_dirty_max, os_cache_max are WT_SESSION::create configuration
flags, not wiredtiger_open.
Make more of ex_all run, I want to test some session configuration strings.
Create/drop the table we're manipulating, otherwise we don't get config
checking on the configuration strings.
