    Issue 5917: ly:performance-headers and \midi { after-writing }

    Change ly:performance-header into ly:performance-headers, returning a
    list of visible header modules from innermost to outermost.  Before,
    only the innermost header was provided, so the values of variables
    defined in outer headers were not accessible.

    If the \midi block defines a function called after-writing, LilyPond
    calls it after writing the MIDI file.  Apart from its use in regression-
    testing ly:performance-headers, it offers a way for an advanced user to
    dump metadata associated with each performance.  For example, the
    function could open a file and dump all header variables in YAML format
    for use in a scripted workflow where the information ends up in ID3 tags
    in an mp3 file.
