The particular sequence of configuration settings that has been known to trigger the failure is:

```
"async=(ops_max=false,threads=),checkpoint=(),eviction=(),shared_cache=(name=0),statistics_log=()",
"cache_size=false,eviction=(threads_max=true),lsm_manager=()",
"async=(ops_max=-1),eviction_trigger=0,verbose=-1",
"eviction_trigger=/data/db/swag,statistics=/data/db/swag",
"eviction=(threads_max=0),statistics=(),verbose=[]",
"lsm_manager=(),shared_cache=(chunk=[object Object],size=/data/db/swag)",
"cache_size=-1,lsm_manager=()",
"",
"",
```

Our first step in fixing this issue should be to create a Python test case that can reproduce the bug.

Message: WT-2709 connection reconfigure segfault in __wt_conn_cache_pool_destroy (#2811)

Clear the WT_CONN_CACHE_POOL flag when the shared cache is destroyed so
reconfigure won't try and destroy it more than once.

This commit replaces a number of previous backports with the original
change, so some of the tickets listed below may have been resolved in
previous versions already as a backport to the v3.2 branch. For example,

this commit replaces that change with 1f4aaa44 itself.
