Revert "gkeyfile: Temporarily re-allow invalid escapes when parsing strings"
This reverts commit 4a967276.
It was a temporary workaround to prevent disruption to apps late on in
the 2.78 cycle. Since we’re now early in the 2.80 cycle, let’s revert
the workaround and allow apps more time to fix their error handling for
GKeyFile
.
