Refactor cmd targets to use a common implicit rule recipe.
Change "make all" to include them all.

If --nat extip:1.2.3.4 option is specified, the port mapping logic
(AddMapping/DeleteMapping) does nothing.
This optimization avoids running a goroutine for doing nothing.

Fixes lint errors:
turbo/snapshotsync/block_snapshots_test.go:77:69: not enough arguments in call to findAndMergeBlockSegments (typecheck)
	_, err := findAndMergeBlockSegments(context.Background(), s, dir, 1)
turbo/snapshotsync/block_snapshots_test.go:88:68: not enough arguments in call to findAndMergeBlockSegments (typecheck)
	_, err = findAndMergeBlockSegments(context.Background(), s, dir, 1)

Add explicit Context to ListenV4 and ListenV5.
This makes it possible to stop listening by an external signal.

Silence non-important comments in the "make erigon" output.

* use "log" for struct fields
* use "logger" for function parameters and local vars

This is a compromise between:
1) using logger := log.New() to avoid aliasing (log := log.New())
2) and keeping it short when logging e.g.: srv.log.Info(...)
