pangomm-2.41.5-bp151.3.2

- Export CXXFLAGS="-std=c++17" until upstream catches up: required,
  as libsigc++-3.0 moved to C++17.

- Add pangomm-glibmm-fix.patch: Fix build with new glibmm,
  following replace pkgconfig(glibmm-2.56) with
  pkgconfig(glibmm-2.58) BuildRequires, and add libtool and
  mm-common BuildRequires and pass autogen.sh as the patch touches
  buildsystem.

- Modernize spec-file by calling spec-cleaner

- Update to version 2.41.5:
  + No visible changes.
- Update '+' in GPL/LGPL License tags to '-or-later', add GPL
  version 3 and change LGPL version to 2.1 in the preamble's
  License tag. And add GPL/LGPL License tags to all subpackages to
  comply with the copyrights.
- Drop unneeded standard BuildRoot tag declaration: RPM already
  handles this itself.
- Point fdupes to the data directory under the build root instead
  of the build root directly, which is a practice that must be
  avoided.
- Recommend the documentation subpackage.

- Update package summaries.
  Avoid running fdupes across hardlink boundaries.

  BuildRequires following upstream changes.
