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.

// There are two basic forms of node designators

// - incomplete nodes, which only have the public key (node ID)
|
|
// - complete nodes, which contain the public key and IP/Port information
|
|

|

// For incomplete nodes, the designator must look like one of these
|
|
//
|
|
// enode://<hex node id>
|
|
// <hex node id>
|
|
//
|
|
// For complete nodes, the node ID is encoded in the username portion
|
|
// of the URL, separated from the host by an @ sign. The hostname can
|
|
// only be given as an IP address, DNS domain names are not allowed.
|
|
// The port in the host name section is the TCP listening port. If the
|
|
// TCP and UDP (discovery) ports differ, the UDP port is specified as
|
|
// query parameter "discport".
|
|
//
|
|
// In the following example, the node URL describes
|
|
// a node with IP address 10.3.58.6, TCP listening port 30303
|
|
// and UDP discovery port 30301.

// enode://<hex node id>@10.3.58.6:30303?discport=30301
