Change the lintMetricTypeInName linter inside promlint to only trigger an error when the metric name matches the type of the metric.

Due to an inconsistency in the text protocol between encoding and
decoding, it was not possible to use the testutil.CollectAndCompare
function to test metrics with empty help values. To fix this, normalize
empty help values from the expected/want side of the test so that they
compare correctly with empty values on the actual/got side of the test.

We tested this function runtime in both cases using "testing",
and the runtime for this pr is much shorter.

Now that we have also added CollectAndLint and GatherAndLint, I
thought we should bring CollectAndCount in line. So:
- Add GatherAndCount.
- Add filtering by metric name.
- Add tests.
Minor wart: CollectAndCount should now return `(int, error)`, but that
would be a breaking change as the current version just returns
`int`. I decided to let the new version panic when it should return an
error. An error is anyway very unlikely, so the biggest annoyance here
is really just the inconsistency.

Also, change all the `dto.MetricFamily` arguments to pointers to be
more consistent with what we do in client_golang in general.

reflect.DeepEqual is not suitable for zero occurrences of repeated
proto messages. This changes the comparison to act on the string
representation of proto messages.

This is for types we don't want to export but which are used in
different packages within client_golang.
Currently, that's only NormalizeMetricFamilies (used in the prometheus
package and in the testutil package). More to be added as needed.

- Expected text format is now read from an io.Reader.
- Metrics are gathered from a Gatherer.
- Added a convenience wrapper to collect from a Collector.

`testutil` is more in line with stdlib naming conventions.
The package should be below `prometheus` as it only provides utils to
test exposition code, not to test HTTP client code.
