** <h3>Special sqlite_stat1 Handling</h3>
**
** As of SQLite version 3.22.0, the "sqlite_stat1" table is an exception to
** some of the rules above. In SQLite, the schema of sqlite_stat1 is:
** <pre>
** &nbsp; CREATE TABLE sqlite_stat1(tbl,idx,stat)
** </pre>
**
** Even though sqlite_stat1 does not have a PRIMARY KEY, changes are
** recorded for it as if the PRIMARY KEY is (tbl,idx). Additionally, changes
** are recorded for rows for which (idx IS NULL) is true. However, for such
** rows a zero-length blob (SQL value X'') is stored in the changeset or
** patchset instead of a NULL value. This allows such changesets to be
** manipulated by legacy implementations of sqlite3changeset_invert(),
** concat() and similar.
**
** The sqlite3changeset_apply() function automatically converts the
** zero-length blob back to a NULL value when updating the sqlite_stat1
** table. However, if the application calls sqlite3changeset_new(),
** sqlite3changeset_old() or sqlite3changeset_conflict on a changeset
** iterator directly (including on a changeset iterator passed to a
** conflict-handler callback) then the X'' value is returned. The application
** must translate X'' to NULL itself if required.
**
** Legacy (older than 3.22.0) versions of the sessions module cannot capture
** changes made to the sqlite_stat1 table. Legacy versions of the
** sqlite3changeset_apply() function silently ignore any modifications to the
** sqlite_stat1 table that are part of a changeset or patchset.

** CAPI3REF: Rebasing changesets
** EXPERIMENTAL
**
** Suppose there is a site hosting a database in state S0. And that
** modifications are made that move that database to state S1 and a
** changeset recorded (the "local" changeset). Then, a changeset based
** on S0 is received from another site (the "remote" changeset) and
** applied to the database. The database is then in state
** (S1+"remote"), where the exact state depends on any conflict
** resolution decisions (OMIT or REPLACE) made while applying "remote".
** Rebasing a changeset is to update it to take those conflict
** resolution decisions into account, so that the same conflicts
** do not have to be resolved elsewhere in the network.
**
** For example, if both the local and remote changesets contain an
** INSERT of the same key on "CREATE TABLE t1(a PRIMARY KEY, b)":
**
** local: INSERT INTO t1 VALUES(1, 'v1');
** remote: INSERT INTO t1 VALUES(1, 'v2');
**
** and the conflict resolution is REPLACE, then the INSERT change is
** removed from the local changeset (it was overridden). Or, if the
** conflict resolution was "OMIT", then the local changeset is modified
** to instead contain:
**
** UPDATE t1 SET b = 'v2' WHERE a=1;
**
** Changes within the local changeset are rebased as follows:
**
** <dl>
** <dt>Local INSERT<dd>
** This may only conflict with a remote INSERT. If the conflict
** resolution was OMIT, then add an UPDATE change to the rebased
** changeset. Or, if the conflict resolution was REPLACE, add
** nothing to the rebased changeset.
**
** <dt>Local DELETE<dd>
** This may conflict with a remote UPDATE or DELETE. In both cases the
** only possible resolution is OMIT. If the remote operation was a
** DELETE, then add no change to the rebased changeset. If the remote
** operation was an UPDATE, then the old.* fields of change are updated
** to reflect the new.* values in the UPDATE.
**
** <dt>Local UPDATE<dd>
** This may conflict with a remote UPDATE or DELETE. If it conflicts
** with a DELETE, and the conflict resolution was OMIT, then the update
** is changed into an INSERT. Any undefined values in the new.* record
** from the update change are filled in using the old.* values from
** the conflicting DELETE. Or, if the conflict resolution was REPLACE,
** the UPDATE change is simply omitted from the rebased changeset.
**
** If conflict is with a remote UPDATE and the resolution is OMIT, then
** the old.* values are rebased using the new.* values in the remote
** change. Or, if the resolution is REPLACE, then the change is copied
** into the rebased changeset with updates to columns also updated by
** the conflicting remote UPDATE removed. If this means no columns would
** be updated, the change is omitted.
** </dl>
**
** A local change may be rebased against multiple remote changes
** simultaneously. If a single key is modified by multiple remote
** changesets, they are combined as follows before the local changeset
** is rebased:
**
** <ul>
** <li> If there has been one or more REPLACE resolutions on a
** key, it is rebased according to a REPLACE.
**
** <li> If there have been no REPLACE resolutions on a key, then
** the local changeset is rebased according to the most recent
** of the OMIT resolutions.
** </ul>
**
** Note that conflict resolutions from multiple remote changesets are
** combined on a per-field basis, not per-row. This means that in the
** case of multiple remote UPDATE operations, some fields of a single
** local change may be rebased for REPLACE while others are rebased for
** OMIT.
**
** In order to rebase a local changeset, the remote changeset must first
** be applied to the local database using sqlite3changeset_apply_v2() and
** the buffer of rebase information captured. Then:
**
** <ol>
** <li> An sqlite3_rebaser object is created by calling
** sqlite3rebaser_create().
** <li> The new object is configured with the rebase buffer obtained from
** sqlite3changeset_apply_v2() by calling sqlite3rebaser_configure().
** If the local changeset is to be rebased against multiple remote
** changesets, then sqlite3rebaser_configure() should be called
** multiple times, in the same order that the multiple
** sqlite3changeset_apply_v2() calls were made.
** <li> Each local changeset is rebased by calling sqlite3rebaser_rebase().
** <li> The sqlite3_rebaser object is deleted by calling
** sqlite3rebaser_delete().
