D7594: Update to synctex 1.19

[Henrik Fehlauer]

rkflx created this revision.
Restricted Application added a project: Okular.

REVISION SUMMARY
  This should prevent crashes when reloading some synctex-enabled pdf
  files created with newer versions of TeXLive. We also gain bugfixes,
  features and improved accuracy from the last 6 years of synctex
  development.
  
  Procedure followed:
  
  - svn co svn://tug.org/texlive/trunk/Build/source/texk/web2c/synctexdir
  - Check out revision 45150
  - Update files present in core/synctex/*
  - Adapt Okular code to changes
  - Review and drop or update/apply old patches using quilt
  - Create missing patches for local synctex changes
  - New patch: Omit warning message when opening non-synctex pdf
  - Two new patches to fix more compiler warnings
  
  TODO for later:
  
  - Move sync file detection code to Okular to never call into synctex C code for non-synctex files
  - Evaluate feasibility of upstreaming all patches for TeXLive 2018 and using synctex as a library
  
  BUG: 383915
  FIXED-IN: 17.12.0

TEST PLAN
  - No crash in synctex on reloading empty.pdf from bugreport anymore.
  - Shift-clicking on a word in a simple pdf opens Kate with the corresponding tex line.
  - Works with tex files from both TeXLive 2015 and 2017.
  - PartTest::testForwardPDF still passes.
