[ENHANCEMENT] TSDB: Improve calculation of space used by labels (#13880)
* [ENHANCEMENT] TSDB: Improve calculation of space used by labels

The labels for each series in the Head take up some some space in the
Postings index, but far more space in the `memSeries` structure.

Instead of having the Postings index calculate this overhead, which is
a layering violation, have the caller pass in a function to do it.

Provide three implementations of this function for the three Labels
versions.

Bryan Boreham 5571c7dc98 FastRegexMatcher: use stack memory for lowercase copy of string
Up to 32-byte values this saves garbage, runs faster.
For prefixes, only `toLower` the part we need for the map lookup.

Split toNormalisedLower into fast and slow paths, to avoid a penalty
for the `copy` call in the case where no allocations are done.

György Krajcsovits eafe72a0d0 perf(nhcb): optimize away most allocations in convertnhcb
In general aim for the happy case when the exposer lists the buckets
in ascending order.

Use Compact(2) to compact the result of nhcb convert.

This is more in line with how client_golang optimizes spans vs
buckets.

fix(nhcb): created timestamp fails when keeping classic histograms (#15218)
The wrong source was used to return the created timestamp, leading to
index out of bound panic. One line fix.

Refactor the requirement test to be generic and be able to
test OpenMetrics and Prom parsers as well.
There are some differencies in what the parsers support, the Prom
parser doesn't have created timestamp.

The protobuf parser uses different formatting to identify the metric
for the scrape loop.
Each parser represents the sample timestamp differently.

beorn7 0f760f63dd lint: Revamp our linting rules, mostly around doc comments
Several things done here:

- Set `max-issues-per-linter` to 0 so that we actually see all linter
  warnings and not just 50 per linter. (As we also set
  `max-same-issues` to 0, I assume this was the intention from the
  beginning.)

- Stop using the golangci-lint default excludes (by setting
  `exclude-use-default: false`. Those are too generous and don't match
  our style conventions. (I have re-added some of the excludes
  explicitly in this commit. See below.)

- Re-add the `errcheck` exclusion we have used so far via the
  defaults.

- Exclude the signature requirement `govet` has for `Seek` methods
  because we use non-standard `Seek` methods a lot. (But we keep other
  requirements, while the default excludes completely disabled the
  check for common method segnatures.)

- Exclude warnings about missing doc comments on exported symbols. (We
  used to be pretty adamant about doc comments, but stopped that at
  some point in the past. By now, we have about 500 missing doc
  comments. We may consider reintroducing this check, but that's
  outside of the scope of this commit. The default excludes of
  golangci-lint essentially ignore doc comments completely.)

- By stop using the default excludes, we now get warnings back on
  malformed doc comments. That's the most impactful change in this
  commit. It does not enforce doc comments (again), but _if_ there is
  a doc comment, it has to have the recommended form. (Most of the
  changes in this commit are fixing this form.)

- Improve wording/spelling of some comments in .golangci.yml, and
  remove an outdated comment.

- Leave `package-comments` inactive, but add a TODO asking if we
  should change that.

- Add a new sub-linter `comment-spacings` (and fix corresponding
  comments), which avoids missing spaces after the leading `//`.
