In the future, we might want to support special swap intervals. To
prevent applications from expecting nonzero values of vsync to be the
same as "on", fail with SDL_Unsupported() if the value passed is neither
0 nor 1.
Currently, if an application wants to toggle VSync, they'd have to tear
down the renderer and recreate it. This patch fixes that by letting
applications call SDL_RenderSetVSync().
This is the same as the patch in #3673, except it applies to all
renderers (including PSP, even thought it seems that the VSync flag is
disabled for that renderer). Furthermore, the renderer flags also change
as well, which #3673 didn't do. It is also an API instead of using hint
callbacks (which could be potentially dangerous).
Closes#3673.
The version with an implicit pattern rule tended to fail if test/
was built in an "out-of-tree" build directory not below test/, for
example:
cd SDL
mkdir _build-test
( cd _build-test; ../test/configure )
make -C _build-test
as a result of the pattern rule first checking for axis.bmp, then for
../test/axis.bmp, then ../test/../test/axis.bmp, and so on until the
maximum path length was reached.
Note that this requires GNU make. The FreeBSD ports file for SDL seems
to use GNU make (gmake) already, so presumably SDL's build system is
already relying on GNU make extensions.

AC_CONFIG_AUX_DIRS is an undocumented, internal version of
AC_CONFIG_AUX_DIR that takes a whitespace-separated list, instead of a
single path to add to the list. It also does not automatically treat
the given path as being relative to the $srcdir, unlike the documented
AC_CONFIG_AUX_DIR.
Newer versions of autoconf treat the argument to AC_CONFIG_AUX_DIRS
as being literal (they do not expand the shell variable), causing
autoreconf to fail if $srcdir is explicitly specified. The argument to
AC_CONFIG_AUX_DIR is checked relative to $srcdir anyway, so there is no
need to specify $srcdir a second time.

See SDL bug #4703. This implements two new hints:
- SDL_APP_NAME
- SDL_SCREENSAVER_INHIBIT_ACTIVITY_NAME
The former is the successor to SDL_HINT_AUDIO_DEVICE_APP_NAME, and acts
as a generic "application name" used both by audio drivers and DBUS
screensaver inhibition. If SDL_AUDIO_DEVICE_APP_NAME is set, it will
still take priority over SDL_APP_NAME.
The second allows the "activity name" used by
org.freedesktop.ScreenSavver's Inhibit method, which are often shown in
the UI as the reason the screensaver (and/or suspend/other
power-managment features) are disabled.
The recent change to make SDL_AUDIODRIVER support comma-separated lists
broke the previous behavior where an SDL_AUDIODRIVER that was empty
behaved the same as if it was not set at all. This old behavior was
necessary to paper over differences in platforms where SDL_setenv may
or may not actually delete the env var if an empty string is specified.
This patch just adds a simple check to ensure SDL_AUDIODRIVER is not
empty before using it, restoring the old interpretation of the empty
var.
