Don't spew a warn!() in reset() if num_colors is 0, because
non-color-supporting terminals are legit. Use debug!() there instead.
Continue spewing warn!() if we believe the terminal to support colors.
Use a better warning when the `op` capability can't be found.
Instead of determining paths from the path tag, we iterate through
modules' children recursively in the metadata. This will allow for
lazy external module resolution.
Unlike fg() and bg(), we haven't already checked for the presence of
"op" in the terminfo when we call reset(), so we need to handle the case
where it's missing.
Also update the warn!() lines to avoid double-quoting the output.
Fixes#7431.

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.

Remove PriorityQueue::each and replace it with PriorityQueue::iter,
which ultimately calls into vec::VecIterator via PriorityQueueIterator.
Implement iterator::Iterator for PriorityQueueIterator. Now you should
be able to do:
extern mod extra;
let mut pq = extra::priority_queue::PriorityQueue::new();
pq.push(5);
pq.push(6);
pq.push(3);
for pq.iter().advance |el| {
println(fmt!("%d", *el));
}
just like you iterate over vectors, hashmaps, hashsets etc. Note that
the iteration order is arbitrary (as before with PriorityQueue::each),
and _not_ the order you get when you pop() repeatedly.
Add an in-file test to guard this.

Move all the colors into a nested mod named color instead of prefixing
with "color_".
Define a new type color::Color, and make this a u16 instead of a u8 (to
allow for easy comparisons against num_colors, which is a u16).
Remove color_supported and replace it with num_colors.
Teach fg() and bg() to "dim" bright colors down to the normal intensity
if num_colors isn't high enough.
Remove unnecessary copies, and fix a bug where a terminfo parse failure
would try to use the wrong error and end up failing.
Reopening of #7031, Closes#6963
I imagine though that this will bounce in bors once or twice... Because attributes can't be cfg(stage0)'d off, there's temporarily a lot of new stage0/stage1+ code.
