patches: fix I2 body indent and I3 childFrameLastCandidate type

I2: Re-indent body of MINI_WINDOW_P if-block in 0008 from 6 spaces to
8 spaces, consistent with GNU style (if at 6 spaces, body at 8).

I3: Change childFrameLastCandidate from char* to NSString*.
Replaces xstrdup/xfree/strcmp with ObjC retain/release/isEqualToString:,
which is consistent with surrounding ObjC code style and avoids
heap allocation with xmalloc.
