Implements review commentary 
Specifically @beorn7 pointed out that the previous implementation had
some shortcomings around large numbers. I've changed the code to match
the suggestion in review, as well as added a few test cases.

That's the same bug fixed in #342 (which is the deprecated code only
replicated in the `prometheus` package until v0.10 is out).

Will Rouesnel a166207919 http.go: incorrect error message displayed when no metrics encoded error 
The "No metrics encoded" error was erroneously displayed the value of err, not
lastErr.

beorn7 ed379b7d99 Remove remaining references to MetricVec from doc comments 
MetricVec is un-experted by now. godoc handles that correctly by
showing the methods of the embedded un-exported metricVec with the
exported type (CounterVec, SummaryVec, ...) that embeds metricVec.

beorn7 f66cdf0736 Un-export MetricVec 
This is in preparation for "curried" metric vecs, as discussed.

And it's a good thing anyway. The exported MetricVec was from a time
when I thought people would define own Metric types and then create
Vecs of it. That has never happened.

beorn7 14730c70c0 promhttp: Bite the bullet and implement all 32 possible interface combos 
As it turned out, it's not that esay to guess "common" combination of
interface upgrades. So I decided to just implement all 32 possible
combination of interface upgrades. (Only 16 with Go 1.7 and earlier.)

Clearly, this calls for code generation. But right now, we still need
to find out what's the best form of the code. For later additions,
implementing code generation might be useful.

Note that newDelegator is called for each HTTP request. Thus, this
commit aims to make the upgrade selection quick. (After the type
checks, it's just directly accessing an element in a slice.)

- Use local registry to avoid conflicts between tests.
- Expose https://github.com/prometheus/client_golang/issues/299 by
  using ConstLabels in a test.
- Improve example: Buckets and help string must be consistent, even
  if the former is not enforced as of now, but see

Summary will have no objectives then.
