 * Merged tables
 *
 * A ref database kept in a sequence of table files. The merged_table presents a
 * unified view to reading (seeking, iterating) a sequence of immutable tables.
 *
 * The merged tables are on purpose kept disconnected from their actual storage
 * (eg. files on disk), because it is useful to merge tables aren't files. For
 * example, the per-workspace and global ref namespace can be implemented as a
 * merged table of two stacks of file-backed reftables.
