Title: Change the block's signature of `inSavePoint:`.

This is open to discussion, but
```
[db inSavePoint:^BOOL{
return [self performSomethingThatFailsWithNO];
}];
```
looks tastier than
```
[db inSavePoint:^(BOOL *rollback){
BOOL result = [self performSomethingThatFailsWithNO];
if (!result) {
*rollback = YES;
return;
}
}];
```
