[PATCH] MySQL: Free the results when QSqlQuery::finished() is called

Calling mysql_stmt_free_result() frees the results of the last
executed query while keeping the prepared statement valid. This
allows one to keep around prepared QSqlQueries without the overhead
of keeping all the results in memory.

qtbase-opensource-src (5.12.5+dfsg-8) unstable; urgency=medium

  * Revert adding alternative qtbase5-gles-dev dependencies:
    - For qtbase5-private-dev: it is wrong, those who need private headers
      and OpenGL ES specific API should use qtbase5-private-gles-dev, not
      qtbase5-private-dev.
    - For libqt5opengl5-dev: it does not help, libqt5opengl5 uses desktop
      OpenGL specific symbols, so it is not installable with libqt5gui5-gles.
  * Remove explicit libqt5gui5 | libqt5gui5-gles dependencies from the
    platformtheme packages. Rely on ${shlibs:Depends} instead.
  * Override the remaining version-substvar-for-external-package error.
  * Backport fixes for two vulnerabilities:
    - CVE-2020-0569: Do not load plugin from the CWD.
    - CVE-2020-0570: Qt tries to load invalid library from CWD.
  * Make Qt 5 the default configuration in qtchooser, by installing the
    qt-default/qtchooser/default.conf symlink in libqt5core5a package.
  * Bump Standards-Version to 4.5.0, no changes needed.
