In the TCL bindings, make sure Tcl_AppendResult() is always terminated by "(char*)0" and not just "0". (check-in: ea4d23d1c0 user: drh tags: trunk)

Add the OP_Undef and OP_IsUndef opcodes. With these, use the first register in the result register range as the flag to indicate EOF on an INSERT from a SELECT, rather than allocating a separate boolean register for that task. (check-in: 6fb7448550 user: drh tags: coroutine-refactor)

** Register P2 holds an SQL index key made using the
** MakeRecord instructions.  This opcode writes that key
** into the index P1.  Data for the entry is nil.
**
** P3 is a flag that provides a hint to the b-tree layer that this
** insert is likely to be an append.
**
** If P5 contains bet OPFLAG_NCHANGE, then the change counter is
** incremented by this instruction.  If OPFLAG_NCHANGE is clear, then
** the change counter is unchanged.
** If P5 has the OPFLAG_NCHANGE bit set, then the change counter is
** incremented by this instruction.  If the OPFLAG_NCHANGE bit is clear,
** then the change counter is unchanged.
**
** If P5 contains OPFLAG_USESEEKRESULT then the cursor must have just
** done a seek to the spot where the new entry is to be inserted.  This
** flag avoids doing an extra seek.
** If P5 has the OPFLAG_USESEEKRESULT bit set, then the cursor must have
** just done a seek to the spot where the new entry is to be inserted.
** This flag avoids doing an extra seek.
**
** This instruction only works for indices.  The equivalent instruction
** for tables is OP_Insert.
