license: fix and add SPDX license identifiers and drop license comments

This also fixes a few wrong SPDX license identifiers, where the original
license comment indicates GPL-2.0-only.

This is not done manually, but by running the following script:

---

    #!/bin/bash

    # Tool to drop license comments, adding SPDX license identifiers, while preserving
    # copyright comments. The point is not to manually do this task, but perform some
    # hacked up string replacement.

    _cp() {
        /bin/cp "$@"
    }

    _cat() {
        /bin/cat "$@"
    }

    in_file() {
        local T=$(mktemp)

        _cp -f "$1" "$T"
        _cat "$T"
        rm -f "$T"
    }

    out_file() {
        local T=$(mktemp)

        _cat - > "$T"
        _cp -f "$T" "$1"
        rm -f "$T"
    }

        _cat "$@" | awk '{ printf("%s#x#", $0)}'
    }
