(#2924) Improve two recent assertions, one from WT-2798 relating to writing metadata updates to disk that are part of a running transaction, and another from WT-2802 that checks that we don't try to copy values from a cursor without a transaction pinned. The latter doesn't apply to cursors on checkpoints (including chunk cursors in an LSM tree). Copy cursor values before rollback in autocommit. If an autocommit operation such as WT_CURSOR::update touches multiple trees (e.g., multiple column groups in a table, or index updates, or multiple chunks in an LSM tree), then some cursors may have consumed the application's key/value pair when the operation has to roll back. Take a copy of any such values before attempting to retry the operation. Branch: mongodb-3.2 https://github.com/wiredtiger/wiredtiger/commit/41eb2dcaac1ff25654d1503f5e29714576ff8d81
