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 )

* 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.

Move packages out of deprecated pkg directory
...
This creates a new `model` directory and moves all data-model related
packages over there:

All the others are more or less utilities and have been moved to `util`:
