+** An RBU update is divided into two stages:
+**
+** * Stage 1, in which changes are accumulated in an oal/wal file, and
+** * Stage 2, in which the contents of the wal file are copied into the

+**
+** The update is visible to non-RBU clients during stage 2. During stage 1

+**
+** If this API is called during stage 2 of the update, output variable

+** to a value between 0 and 10000 to indicate the permyriadage progress of

+**
+** If this API is called during stage 1 of the update, output variable
+** (*pnTwo) is set to 0 to indicate that stage 2 has not yet started. The
+** value to which (*pnOne) is set depends on whether or not the RBU
+** database contains an "rbu_count" table. The rbu_count table, if it
+** exists, must contain the same columns as the following:
+**
+** CREATE TABLE rbu_count(tbl TEXT PRIMARY KEY, cnt INTEGER) WITHOUT ROWID;
+**
+** There must be one row in the table for each source (data_xxx) table within
+** the RBU database. The 'tbl' column should contain the name of the source
+** table. The 'cnt' column should contain the number of rows within the
+** source table.
+**
+** If the rbu_count table is present and populated correctly and this
+** API is called during stage 1, the *pnOne output variable is set to the
+** permyriadage progress of the same stage. If the rbu_count table does
+** not exist, then (*pnOne) is set to -1 during stage 1. If the rbu_count
+** table exists but is not correctly populated, the value of the *pnOne
