Add the sqlite3_value_dup() and sqlite3_value_free() interfaces and use those

to add the sqlite3_rtree_query_info.apSqlParam field to the query callback
in R-Tree.

 +** CAPI3REF: The pre-update hook.
 +** EXPERIMENTAL
 +**
 +** ^These interfaces are only available if SQLite is compiled using the
 +** [SQLITE_ENABLE_UPDATE_HOOK] compile-time option.
 +**
 +** ^The [sqlite3_preupdate_hook()] interface registers a callback function
 +** that is invoked prior to each [INSERT], [UPDATE], and [DELETE] operation.
 +** ^At most one preupdate hook may be registered at a time on a single
 +** [database connection]; each call to [sqlite3_preupdate_hook()] overrides
 +** the previous setting.
 +** ^The preupdate hook is disabled by invoking [sqlite3_preupdate_hook()]
 +** with a NULL pointer as the second parameter.
 +** ^The third parameter to [sqlite3_preupdate_hook()] is passed through as
 +** the first parameter to callbacks.
 +**
 +** ^The preupdate hook only fires for changes to real tables; the preupdate
 +** hook is not invoked for changes to virtual tables.
 +**
 +** ^The second parameter to the preupdate callback is a pointer to
 +** the [database connection] that registered the preupdate hook.
 +** ^The third parameter to the preupdate callback is one of the constants
 +** [SQLITE_INSERT], [SQLITE_DELETE], or [SQLITE_UPDATE] to indentify the
 +** kind of update operation that is about to occur.
 +** ^(The fourth parameter to the preupdate callback is the name of the
 +** database within the database connection that is being modified.  This
 +** will be "main" for the main database or "temp" for TEMP tables or 
 +** the name given after the AS keyword in the [ATTACH] statement for attached
 +** databases.)^
 +** ^The fifth parameter to the preupdate callback is the name of the
 +** table that is being modified.
 +** ^The sixth parameter to the preupdate callback is the initial [rowid] of the
 +** row being changes for SQLITE_UPDATE and SQLITE_DELETE changes and is
 +** undefined for SQLITE_INSERT changes.
 +** ^The seventh parameter to the preupdate callback is the final [rowid] of
 +** the row being changed for SQLITE_UPDATE and SQLITE_INSERT changes and is
 +** undefined for SQLITE_DELETE changes.
 +**
 +** The [sqlite3_preupdate_old()], [sqlite3_preupdate_new()],
 +** [sqlite3_preupdate_count()], and [sqlite3_preupdate_depth()] interfaces
 +** provide additional information about a preupdate event. These routines
 +** may only be called from within a preupdate callback.  Invoking any of
 +** these routines from outside of a preupdate callback or with a
 +** [database connection] pointer that is different from the one supplied
 +** to the preupdate callback results in undefined and probably undesirable
 +** behavior.
 +**
 +** ^The [sqlite3_preupdate_count(D)] interface returns the number of columns
 +** in the row that is being inserted, updated, or deleted.
 +**
 +** ^The [sqlite3_preupdate_old(D,N,P)] interface writes into P a pointer to
 +** a [protected sqlite3_value] that contains the value of the Nth column of
 +** the table row before it is updated.  The N parameter must be between 0
 +** and one less than the number of columns or the behavior will be
 +** undefined. This must only be used within SQLITE_UPDATE and SQLITE_DELETE
 +** preupdate callbacks; if it is used by an SQLITE_INSERT callback then the
 +** behavior is undefined.  The [sqlite3_value] that P points to
 +** will be destroyed when the preupdate callback returns.
 +**
 +** ^The [sqlite3_preupdate_new(D,N,P)] interface writes into P a pointer to
 +** a [protected sqlite3_value] that contains the value of the Nth column of
 +** the table row after it is updated.  The N parameter must be between 0
 +** and one less than the number of columns or the behavior will be
 +** undefined. This must only be used within SQLITE_INSERT and SQLITE_UPDATE
 +** preupdate callbacks; if it is used by an SQLITE_DELETE callback then the
 +** behavior is undefined.  The [sqlite3_value] that P points to
 +** will be destroyed when the preupdate callback returns.
 +**
 +** ^The [sqlite3_preupdate_depth(D)] interface returns 0 if the preupdate
 +** callback was invoked as a result of a direct insert, update, or delete
 +** operation; or 1 for inserts, updates, or deletes invoked by top-level 
 +** triggers; or 2 for changes resulting from triggers called by top-level
