change foreign links flags code to use bitmasks

Zach was doing a lot of integer comparisons on the Foreign_link sync
fields. I switched them to use named bitmasks instead. I also switched
the semantics of bit 3 to be the opposite of what Zach had -- I find
lots of double-negatives in a checkbox to be hard to read.
