[Philip Withnall <pwithnall src gnome org>]

commit ea8c09f14da4b931cdadbabe2be315f6747ac7b7
Author: Philip Withnall <withnall endlessm com>
Date:   Tue Aug 14 16:00:13 2018 +0100

    build: Enable G_LOG_USE_STRUCTURED=1
    
    This enables structured logging for all parts of dconf, which will make
    it easier to check for certain log messages in the unit tests.
