Thanks for the fixes!

1. We now have mem_value_bool(), and so as to be consistent
it would be better to name this function mem_set_bool(), not
vdbe_mem_set_bool(). It does not take struct Vdbe pointer
anyway.

2. Is there any concrete reason why vdbe_mem_set_bool() is
not used now in the following places?

vdbe.c:1101
	pOut = out2Prerelease(p, pOp);
	assert(pOp->p1 == 1 || pOp->p1 == 0);
	pOut->flags = MEM_Bool;
	pOut->u.b = pOp->p1;
	break;

vdbe.c:2275
	memAboutToChange(p, pOut);
	MemSetTypeFlag(pOut, MEM_Bool);
	pOut->u.b = res2;
	REGISTER_TRACE(pOp->p2, pOut);

vdbe.c:2471
	pOut->u.b = v1;
	MemSetTypeFlag(pOut, MEM_Bool);

vdbe.c:2495
	pOut->flags = MEM_Bool;
	pOut->u.b = ! pIn1->u.b;

If it works for them, then I propose to move vdbe_mem_set_bool()
to the patch 'sql: introduce type boolean', and use it.

Also, please, consider this minor review fix, on the branch:
