[LTP] [PATCH 2/2] safe_stdio: Error messages in new format

[Mats L. <mat...@en...>]

safe_macros.c introduced a new format of error messages using the following
syntax:
<file>:<line> <function>(<parameters>) failed <optional extra message>

This patch will introduce this format to safe_stdio.c as well.
