fixes bug #5241 ( https://bugzilla.libsdl.org/show_bug.cgi?id=5241 ) --
patch from pj5085.

branch : SDL-1.2

From maxi@daemonizer.de:

Since some time I stated to observe an annoying bug with the forward
movement suddenly stopping while I was still pressing the corresponding
key for the forward movement. Releasing and pressing the key again
continued the movement. I observed this in the game "Unreal Tournament
2004", but other software is probably also affected. The stop basically
happens after a few minutues of pressing the key, though the time needed
to reproduce the issue is not constant.

While investigating the issue I found it started with a commit [1] in
the Xorg xserver. Digging deeper into the code I found two commits [2]
[3] in libsdl2 which looked like they would also fix the issue in
libsdl1.2. I backported these two commits to the libsdl1.2 in Debian
and can confirm that the bug got fixed by this.

When the kernel reports absinfo.minimum > absinfo.maximum, the
coefficient value was previously incorrectly calculated.

This ioctl never made it to upstream Linux.
Besides, with KMS drivers page-flipping already happens in the vblank.

The /dev/ttyX nodes obey the same rules as others, it's possible to use
them as non-root users provided that the access rights bits are
correctly set.

 shell
When not started from a shell, SDL was segfaulting while trying to
detach the process from the controlling terminal.

However, it doesn't make any sense for an SDL app to detach from
its controlling terminal, unless the app is a daemon. Since we
have never seen a SDL app detach from its controlling terminal,
even when starting it from a shell, the feature was probably broken.
Thus, the code has been dropped.

 framebuffer
By setting the environment variable SDL_FBCON_DONT_CLEAR, the
application won't clear the framebuffer when exiting.

We use it inside an app launcher, which will set this variable before
exiting, in order for the loading screen to stay visible until the
launched application takes hand.

When the video subsystem is initialized, the framebuffer might not be in
the video mode that the application targets. In that case, if we don't
clear the framebuffer, for a short moment the display will show the
previous image distorded by the mode change.

 resolution
If an exact resolution match is not found, SDL will accept a higher
resolution and add black bars around it. For example, when 320x200 is
requested by only 320x240 is available, it will add 20 black lines on
the top and the bottom of the screen. The surface that SDL returns to
the application will look like it actually got 320x200.

When double buffering, the actual video mode's height should be used
instead of the height before adding the black borders. For the pixel
pointer this was done correctly, but for the vertical panning offset
the wrong height was used.

When not using the old Linux input event interface, SDL parses the
name of a device to know what it's capable of. It expects the
name to match the following string: "Analog %d-axis %d-button %d-hat".

This patch allows to use devices with a custom name.
For instance: "My Joystick Device (Analog 2-axis 6-button 2-hat)"
