session-terminate in lily.scm

David, many thanks for working on this!

The variables declared per session are:

1) bar-glyph-alist
defined as empty list and filled with strings in scm/bar-line.scm

2) span-bar-glyph-alist
see above

3) volta-bracket-allow-volta-hook-list
see above

4) bar-glyph-print-procedures
this is a quasiquoted list and holds the bar line drawing
functions. It is predefined during scm/bar-line.scm *and*
another glyph/drawing function is added within the fishy
reg test bar-line-define-bar-glyph.ly.

I don't know much about garbage collection, but it seems to
me that storing the function calls in a quasiquote list
seems to confuse lilypond's internals.
