        xsrc/external/mit/libXxf86dga/dist/src: XF86DGA.c

Log Message:
Fix "no output of xdpyinfo(1) on redirect or pipe" problem.

XF86cleanup() in libXxf86dga invoked via atexit(3)
(or __attribute__((__destructor__)) in NetBSD xsrc)
calls _exit(2) directly so fflush(3) via normal exit(3)
is not called.  Analyzed by rin@, ryo@, and soda@:
 https://mail-index.netbsd.org/tech-x11/2021/01/20/msg002192.html

Should be pulled up to netbsd-9.

XXX1: The original XF86cleanup() is not async-signale-safe.
XXX2: XF86DGAGetVideo() implicitly overrides signal handlers.
