#5181 Integrate lone post-events into surrounding expressions.

[David Kastrup]

Integrate lone post-events into surrounding expressions.

Reattaching post-events to a preceding music variable or music
function call (or expression) is often desired but was unsupported.

The problem with supporting such expressions everywhere is that it
breaks the use of

c-\single \dynamicUp \f

since then \f is attached to \dynamicUp instead of becoming the second
argument to \single, due to operator precedence. So reattaching lone
post-events is only done with lower precedence in selected constructs.

This issue does not yet contain regression tests, changes entries, or
documentation. I would want to solicit feedback on how useful people
find it since it messes with the syntax.

Contains commits (reverse order):

Integrate lone post-events into chords

Reattaching post-events to a preceding music variable or music
function call (or expression) is often desired but was unsupported.
This commit caters for the support inside of chords.

Allow lone postevents in braced lists

Reattaching post-events to a preceding music variable or music
function call (or expression) is often desired but was unsupported.

This commit caters for the support in braced lists.

Parser: Add reverse_music_list function

This function does not just reverse a music list but also integrates
post events into the respective preceding expressions. If that is not
possible, a warning is printed and they are either dropped or attached
to an empty chord (depending on a call parameter). If a list consists
only of post-events, it might be returned as a post-event, too.
Again, depending on a parameter. This is useful for #{ -2 -3 #} and
its ilk.

Also adds add_post_events function.
