Fix FastRegexMatcher matching multibyte runes with . (#14059)
When `zeroOrOneCharacterStringMatcher` wach checking the input string,
it assumed that if there are more than one bytes, then there are more
than one runes, but that's not necessarily true.

Bryan Boreham 7c28521451 [TESTS] Truncate some long test names, for readability
The strings produced by these tests can run to thousands of characters,
which makes test logs difficult to read.

Allow downstream projects to use faster regexp (#10251)
* Add benchmark for FastRegexMatcher

Signed-off-by: Bryan Boreham <bjboreham@gmail.com>

* Use modified regexp package with optimisations

See https://github.com/grafana/regexp/tree/speedup#readme

Includes the following changes proposed upstream:
* [regexp: allow patterns with no alternates to be one-pass](https://go-review.googlesource.com/c/go/+/353711)
* [regexp: speed up onepass prefix check](https://go-review.googlesource.com/c/go/+/354909)
* [regexp: handle prefix string with fold-case](https://go-review.googlesource.com/c/go/+/358756)
* [regexp: avoid copying each instruction executed](https://go-review.googlesource.com/c/go/+/355789)
* [regexp: allow prefix string anchored at beginning](https://go-review.googlesource.com/c/go/+/377294)

Signed-off-by: Bryan Boreham <bjboreham@gmail.com>

* Use regexp code identical to upstream Go

Change `grafana/regexp` import to use `main` branch.

This means Prometheus is not using the proposed optimisations, but
downstream users of Prometheus code are able to `replace` the library
with the `speedup` branch which does.

beorn7 c954cd9d1d Move packages out of deprecated pkg directory
This creates a new `model` directory and moves all data-model related
packages over there:
  exemplar labels relabel rulefmt textparse timestamp value

All the others are more or less utilities and have been moved to `util`:
  gate logging modetimevfs pool runtime
