About branch wal2

This branch contains the two-wal-files patch only. This patch adds an extra journal mode enabled by "PRAGMA journal_mode = wal2". The advantage of this journal mode over regular "wal" mode is that writers may continue writing to one wal file while the other is checkpointed. The fossil trunk is periodically merged into this branch.
