//	** CAPI3REF: Dynamically Typed Value Object
//	** KEYWORDS: {protected sqlite3_value} {unprotected sqlite3_value}
//	**
//	** SQLite uses the sqlite3_value object to represent all values
//	** that can be stored in a database table. SQLite uses dynamic typing
//	** for the values it stores.  ^Values stored in sqlite3_value objects
//	** can be integers, floating point values, strings, BLOBs, or NULL.
//	**
//	** An sqlite3_value object may be either "protected" or "unprotected".
//	** Some interfaces require a protected sqlite3_value.  Other interfaces
//	** will accept either a protected or an unprotected sqlite3_value.
//	** Every interface that accepts sqlite3_value arguments specifies
//	** whether or not it requires a protected sqlite3_value.  The
//	** [sqlite3_value_dup()] interface can be used to construct a new
//	** protected sqlite3_value from an unprotected sqlite3_value.
//	**
//	** The terms "protected" and "unprotected" refer to whether or not
//	** a mutex is held.  An internal mutex is held for a protected
//	** sqlite3_value object but no mutex is held for an unprotected
//	** sqlite3_value object.  If SQLite is compiled to be single-threaded
//	** (with [SQLITE_THREADSAFE=0] and with [sqlite3_threadsafe()] returning 0)
//	** or if SQLite is run in one of reduced mutex modes
//	** [SQLITE_CONFIG_SINGLETHREAD] or [SQLITE_CONFIG_MULTITHREAD]
//	** then there is no distinction between protected and unprotected
//	** sqlite3_value objects and they can be used interchangeably.  However,
//	** for maximum code portability it is recommended that applications
//	** still make the distinction between protected and unprotected
//	** sqlite3_value objects even when not strictly required.
//	**
//	** ^The sqlite3_value objects that are passed as parameters into the
//	** implementation of [application-defined SQL functions] are protected.
//	** ^The sqlite3_value objects returned by [sqlite3_vtab_rhs_value()]
//	** are protected.
//	** ^The sqlite3_value object returned by
//	** [sqlite3_column_value()] is unprotected.
//	** Unprotected sqlite3_value objects may only be used as arguments
//	** to [sqlite3_result_value()], [sqlite3_bind_value()], and
//	** [sqlite3_value_dup()].
//	** The [sqlite3_value_blob | sqlite3_value_type()] family of
//	** interfaces require protected sqlite3_value objects.
