`max_by` method returns the element that gives the maximum value from the specfied function.
`max_by`/`min_by` are convenient when you want to get the value which has greatest/smallest scores.
Inspired by [ruby's Enumerable module](http://ruby-doc.org/core-2.0/Enumerable.html).
Mostly just low-haning fruit, i.e. function arguments that were @ even
though & would work just as well.
Reduces librustc.so size by 200k when compiling without -O, by 100k when
compiling with -O.

r? @brson (or @graydon if available) rustpkg/api.rs provides functions intended for package scripts to call.
It will probably need more functionality added to it later, but this is
a start.
Added a test case checking that a package script can use the API.
Closes#6401
... through yields
This avoids the following pathological scenario that makes threadring OOM:
1) task calls C using fast_ffi, borrowing a big stack from the scheduler.
2) task returns from C and places the big stack on the task-local stack segment list
3) task calls further Rust functions that require growing the stack, and for this reuses the big stack
4) task yields, failing to return the big stack to the scheduler.
5) repeat 500+ times and OOM
(reopening after incoming fallout. *do not r+*. broken)
Both extra::treemap::TreeMap and extra::treemap::TreeSet have
corresponding iterators TreeMapIterator and TreeSetIterator.
Unfortunately, the tests and extra::serialize use the older .each.
Update all the dependent code, and remove .each.
