lilypond 2.22.0-1 source package in Ubuntu

Changelog

lilypond (2.22.0-1) unstable; urgency=medium

  * New upstream version 2.22.0 (Closes: #979839, #951801)
  * Remove embedded guile-1.8 and migrate to system guile-2.2
    (Closes: #746005, #852871)
  * debian/gbp.conf: Remove guile18 component
  * debian/{control,rules}: Migrate from python2 to python3
  * debian/rules:
    - Run "make doc" with "-j" option in addition to CPU_COUNT
      as suggested in INSTALL.txt for even faster build
    - Remove "nuke the parser files" workaround
      as lily/out/parser.* no longer exist in upstream source
    - Remove empty override_dh_auto_test-arch
      as the tests no longer fail without built documentation
    - Remove override_dh_auto_test-indep as the added "make test-baseline"
      is not suited for automated Debian builds
    - Try to "git restore configure" in override_dh_auto_clean
  * debian/control:
    - lilypond-doc: Add Replaces: lilypond-doc-html (<< 2.21.82-1~)
      to avoid upgrade error due to web files reorganization
    - Build-depend imagemagick-6.q16 instead of imagemagick.
      "imagemagick" became a dummy package in Debian 9 "stretch",
      and the aspcud resolver used by experimental buildd would install
      graphicsmagick-imagemagick-compat (which Provides: imagemagick)
      which is not that compatible after all and caused lilypond to FTBFS
    - Remove Authors paragraph from package description
      as the development team is much larger than before
    - Bump Standards-Version to 4.5.1 (no change)
  * debian/lilypond.docs: Rename README.txt to README.md as per upstream
  * Adjust documentation install file lists for LilyPond 2.21/2.22:
    - debian/doc_languages.txt: Add PDF package for Portuguese
    - debian/update_doc_packages: Adjust install file lists for new version
    - debian/lilypond-doc.install: Remove the no-longer-existing
      usr/share/doc/lilypond/html/Documentation/*.txt entry
    - Run "debian/rules update-doc-packages"
    - Add debian/not-installed to avoid dh_missing errors with debhelper 13
  * debian/patches: Delete obsolete patches and disable others for now
  * debian/remove_w3c_callback: Recognize https too, to fix Lintian
    privacy-breach-w3c-valid-html errors
  * Adjust debian/lilypond-doc.install and debian/rules
    so that the PNG files stay with lilypond-doc package
  * debian/README.Debian: Minor editing
  * Cherry-pick upstream fixes for potential crashes with Guile 2.2
