These shouldn't be necessary since peers were pruned for the ability to allocate chunks to the current piece.

Drop bradfitz/iter dependency ( #605 )

* Drop bradfitz/iter dependency
`range iter.N` looks nice and doesn't allocate, but unfortunately using a `range` expression blocks a function from being inlined wherever it's used (for now). It's not that we need inlining in all cases, but I do think a C-style for loop looks just as nice and is probably clearer to the majority. There also aren't any clear disadvantages to changing (unless you just happen to dislike the look of C)

Otherwise we reserve requests with the assumption that they can be assigned later, and they actually might not be.
