This PR updates the version of go used in builds and docker to
1.23.0. Release notes: https://go.dev/doc/go1.23
More importantly, following our policy of maintaining the last two
versions (which now becomes 1.23 and 1.22), we can now make use of
the things that were introduced in 1.22: https://go.dev/doc/go1.22
Go 1.22 makes two changes to “for” loops.
- each iteration creates new variables,
- for loops may range over integers
Other than that, some interesting library changes and other stuff.
Since Go 1.22 has deprecated certain elliptic curve operations, this PR removes
references to the affected functions and replaces them with a custom implementation
in package crypto. This causes backwards-incompatible changes in some places.

This changes the CI / release builds to use the latest Go version. It also
upgrades golangci-lint to a newer version compatible with Go 1.19.
In Go 1.19, godoc has gained official support for links and lists. The
syntax for code blocks in doc comments has changed and now requires a
leading tab character. gofmt adapts comments to the new syntax
automatically, so there are a lot of comment re-formatting changes in this
PR. We need to apply the new format in order to pass the CI lint stage with
Go 1.19.
With the linter upgrade, I have decided to disable 'gosec' - it produces
too many false-positive warnings. The 'deadcode' and 'varcheck' linters
have also been removed because golangci-lint warns about them being
unmaintained. 'unused' provides similar coverage and we already have it
enabled, so we don't lose much with this change.
