Bug#1106646: denemo ftbfs with libxml 2.14.x from experimental

[Tj]

Source: denemo
Followup-For: Bug #1106646
X-Debbugs-Cc: tj.iam...@proton.me

I investigated this issue and in the process cleaned up the tests
compilation warnings. With an sbuild that drops to shell when the test
aborts I discovered the issue is that the exported .denemo XML file is
significantly different from the original - it appears as if almost all
child elements of <lilypond-directive> elements are lost. E.g:

root@sbuild:/build/reproducible-path# diff -u
