beorn7 663a9ad019 Make Help strings optional
This is in line with
https://prometheus.io/docs/instrumenting/writing_clientlibs/#metric-description-and-help

Since the zero value of a string in Go is `""`, we cannot distinguish
between a Help string not set and an empty Help string. Thus, we just
make it formally optional here with an encouragement to set it in the
doc comment.

In v0.10, the Help string will probably become a "normal" argument of
the constructor rather than a field in an Opts struct.

beorn7 1b2bd1d665 Make Histogram observations atomic while keeping them lock-free
Fixes #275

This is rather tricky and required some studying of the Go memory
model. I have added copious code comments to explain what's going on.

Benchmarks haven't changed significantly, despite the additional
atomic operations now required during Observe. Write performance is
noticable, but it is also much more involved now and has a mutex. (But
note that Write is supposed to be a relatively rare operation and thus
not in the hot path compared to Observe.) Allocs haven't changed at
all.

beorn7 773f502723 Rework process collector
This unifies both constructors in one with an options argument.

The options argument allows to switch on error reporting, as discussed
in #219.

The change of the contructor signature is breaking, but only mildly
so. Plus, the process collector is rarely used explicitly. I used
Sourcegraph to search for public usages, with the following results:

- 2 occurrences of NewProcessCollectorPIDFn, once in @discordianfish's
  glimpse, once in @fabxc's etcd_exporter (deprecated anyway). Both
  are Prom veterans and will simply do the one line change if needed.
- 8 occurrences of NewProcessCollector, of which 7 are of the form
    NewProcessCollector(os.Getpid(), "")
  Thus, it's a very easy change, which I even hinted at in the doc
  comment.

beorn7 da330f4281 Un-export prometheus.LabelPairSorter
The only known external usage of it was in prometheus/pushgateway,
where it was removed by
https://github.com/prometheus/pushgateway/pull/200 .

Originally, the expectation was that users would implement the Metric
interface now and then. As we know now, neither it is happening, nor
would it make a lot of sense. (Users implement the Collector interface
instead.) By now, LabelPairSorter is essentially noise in the already
quite cluttered namespace in the prometheus package.

beorn7 c06fb788be Relax consistency checks during gathering
Also, clarify in the doc comment.

Previously, the assumption was that inconsistent label dimensions are
violating the exposition format spec. However, especially with the
knowledge that OpenMetrics will explicitly allow inconsistent label
dimensions in expositions, we should allow it in client_golang, too.

Note that registration with proper Descs provided will still check for
consistont label dimensions. However, you can "cheat" with custom
Collectors as you can collect metrics that don't follew the provided
Desc (this will be made more explicit and less cheaty once #47 is
fixed). You can also create expositions with inconsistent label
dimensions by merging Gatherers with the Gatherers slice type. (The
latter is used in the Pushgateway.)

Effectively, normal direct instrumentation will always have consistent
label dimensions in this way, but you can cover special use cases with
custom collectors or merging of different Gatherers.

beorn7 1b56b5c497 Be more robust about nil pointers in protobuf
While not strictly correct, it can easily happen that proto messages
are created that use nil pointers instead of pointers in empty strings
to denote an empty string.
