Merge poppler 0.44.0-3 (main) from Debian unstable (main)

Please merge poppler 0.44.0-3 (main) from Debian unstable (main)

Explanation of the Ubuntu delta and why it can be dropped:
===============================
  * Updated for soname change libpoppler58 -> 61
  * New upstream version (soname update 57->58)
  * debian/patchres/revert_api_change.patch:
    - revert upstream commit that removed an enum, they claim it's
      not an abi change because it's unused, but other packages (bindings)
      rely on it to build still, we can drop the patch later once the
      redpends have been updated
  * Updated for soname change libpoppler56 -> 57
  * Updated for soname change libpoppler52 -> 56
  * Set hardening flags to "+all,-pie" to build with all hardening flags
    except -fPIE.
  * New upstream release (LP: #1449991)
  * Rename packages according to the new SONAMEs:
    - libpoppler49 -> libpoppler52
  * debian/libpoppler-glib8.symbols.in:
  * debian/libpoppler-qt4-4.symbols.in:
  * debian/libpoppler-qt5-1.symbols.in:
    - Updated
  * Explicitly pass --disable-libopenjpeg now - this support was auto-disabled
    before but now configure fails without this flag.
  * Rename packages according to the new SONAMEs:
    - libpoppler47 -> libpoppler49
  * Resynchronise with Debian, remaining changes:
    - Drop libopenjpeg-dev build depends, it is in universe.
    - Lower poppler-data to Suggests, it is too big for CD images,
      handled by language-selector.

All of that is in the Debian package except for these:
====================================
1. Drop libopenjpeg-dev build-depends, it is in universe
- We still need this dropped, except it is now libopenjp2-7-dev
2. Use --disable-libopenjpeg
- Still needed
3. debian/patches/revert_api_change.patch:
- Not needed, see test build results below
4. Lower poppler-data to Suggests since it's too big for CD images
- Since we aren't as concerned about 1 or 2 MBs since we do DVDs instead
of CDs, this seems like an obsolete change. See bug 893920 where we have
language-selector install this for everyone after install anyway.

Test build
==========
https://launchpad.net/~jbicha/+archive/ubuntu/arch/+packages
I did a test build of all of poppler reverse build-dependencies.
- twidge is a haskell package so it's currently unbuildable
- cirkuit unrelated longstanding ftbfs, filed bug 1591557
- gle-graphics FTBFS on armhf - longstanding bug 940842
- calibre FTBFS on arm64 - unrelated qt issue?

- Note that python-poppler did need to be fixed (bug 1528489) but this was done in Debian 2 weeks ago and auto-synced.
- poppler-sharp rebuilt fine but still references the removed POPPLER_ORIENTATION_* enums. This is because it wasn't actually building bindings for the current API, but building for the last time poppler-sharp was updated upstream (poppler 0.18!).
https://github.com/jacintos/poppler-sharp/pull/7
I'll follow up with Debian too.

python-poppler and poppler-sharp are the only 2 of the packages I built to have results when I rgrepped "POPPLER_ORIENTATION" in their source code.

Note for sponsors
=================
boomaga and pdfgrep will need a rebuild after this upload because Debian renamed libpoppler-cpp0 > libpoppler-cpp0v5
