+Subject: [PATCH 3/4] all: get rid of strndupa

+in one case (src/auditd.c) we don't even need to allocate a buffer, in the
+other two we do it in two steps to avoid using a non-standard function.

++.SH NAME
++glxgears \- ``gears'' demo for GLX
++.SH SYNOPSIS
++.B glxgears
++.RI [ options ]
++.SH DESCRIPTION
++The \fIglxgears\fP program is a port of the ``gears'' demo to GLX. It displays
++a set of rotating gears and prints out the frame rate at regular intervals. It
++has become quite popular as basic benchmarking tool.
++.SH OPTIONS
++.TP 8
++.B \-display \fIdisplay\fP
++Specify which X display to run on.
++.TP 8
++.B \-stereo
++Use a stereo enabled GLX visual.
++.TP 8
++.B \-samples \fIN\fP
++Run in multisample mode with at least N samples.
++.TP 8
++.B \-fullscreen
++Run in fullscreen mode.
++.TP 8
++.B \-info
++Display OpenGL renderer information.
++.TP 8
++.B \-geometry \fIWxH+X+Y\fP
++Window geometry.

++.TH glxinfo 1 "2006-11-29"
++.SH NAME
++glxinfo \- show information about the GLX implementation
++.SH SYNOPSIS
++.B glxinfo
++.RI [ options ]
++.SH DESCRIPTION
++The \fIglxinfo\fP program shows information about the OpenGL and GLX
++implementations running on a given X display.
++.PP
++The information includes details about the server- and client-side GLX
++implementation, the OpenGL and GLU implementations as well as a list
++of available GLX visuals.
++.SH OPTIONS
++.TP 8
++.B \-v
++Print visuals info in verbose form.
++.TP 8
++.B \-t
++Print verbose table.
++.TP 8
++.B \-display \fIdisplay\fP
++Specify the X display to interrogate.
++.TP 8
++.B \-h
++Print usage information.
++.TP 8
++.B \-i
++Force an indirect rendering context.
++.TP 8
++.B \-b
++Find the "best" visual and print its number.
++.TP 8
++.B \-l
++Print interesting OpenGL limits.
++.TP 8
++.B \-s
++Print a single extension per line.

++ * The first time a visual is presented to Mesa's pseudo-GLX it
++ * attaches ancilliary buffers to it (like depth and stencil).
++ * But that usually only works if glXChooseVisual is used.
++ * This function calls glXChooseVisual() to sort of "prime the pump"
++ * for Mesa's GLX so that the visuals that get reported actually

+Submitted By: Douglas R. Reno <renodr at linuxfromscratch dot org>
+Date: 2022-02-11
+Initial Package Version: 21.3.6
+Upstream Status: Merge Request (Partial), Self
+Origin: Upstream MR (#10752) with modifications
+Description: Fixes several multi-threading related issues in the
+ Nouveau driver in Mesa. These issues can lead to
+ kernel panics and application crashes, and also cause
+ KDE Plasma in Wayland mode to instantly crash the system
+ once launched on a NVC0 or later card (NV50 is
+ unaffected). My changes include additional PUSH commands
+ to fix timing issues, which will be picked up upstream
+ shortly. Tested with KDE Plasma/Wayland, GNOME, VLC,
+ MPlayer, Minecraft, Discord, Zoom, XINE, and Kdenlive.
