Don't repeat the connection close in start_run() if execute_populate()
already closed it.
whitespace, return the error value from __wt_statlog_log_one() on error.
If the configuration is incorrect for WT_CONNECTION.close, note the
error but keep going, WT_CONNECTION.close isn't going to be retried.
Commit d1b8892 lost the mapping of WT_NOTFOUND to ENOENT, add it back
in explicitly.
Fix FILE handle leak, push FILE handle work down into __statlog_log_one().

While we're at it, close the log FILE handle when we're done, and check
all log FILE handle close calls for errors.
There isn't a old-path/new-path buffer pair: there's an old-path
buffer and a temporary buffer used for the new path and the time
stamp, it's confusing to call the latter "path".
Move connection close/reopen to its own function called by start_run.
