Not everyone who reads PDF's is necessarily a LaTeX user.
These changes allow users to install atril without the huge bagage
of tex-live on systems where synctex isn't provided as a stand alone
library.

GTime is defined to always be a signed 32-bit integer, it will
overflow in the year 2038.

  $ cd cut-n-paste/synctex
  $ rm synctex_*
  $ ./update-synctex-from-TL.sh

Test on Fedora:

  1. Install required packages
     $ sudo dnf install texlive-scheme-basic texlive-lipsum -y

  2. Build a pdf with synctex enabled
     $ cat <<EOF >> file.tex
\documentclass[12pt]{report}
\usepackage{lipsum}
\begin{document}
\chapter{Introduction}
\lipsum[2-4]
\end{document}
EOF
     $ pdflatex -synctex=1 file.tex

   3. Open file.pdf using atril

   4. Search any text string
