Use the existing SDL_GetExeName(), available for all the UNIX
platforms, in the internal GetAppName(); this has few advantanges:
- SDL_GetExeName() (and SDL_GetAppID() that builds on top of it) are
used in various places already; since it caches the executable name,
this may remove one extra read of the application name
- SDL_GetExeName() has a non-dummy implementation in more OSes than
GetAppName(), thus providing a small improvement for this IME
As drive-by change: since SDL_GetExeName() provides a constant string,
there is no more need to allocate a new string in GetAppName(), which
is used as constant string anyway. Hence, return a constant string in
GetAppName() too.

"This thing allows to do something" is not really grammatically correct.
The closest rephrasing would be "allows one to do something" or "allows
the user to do something", but I think the passive voice reads more
naturally here.

This reverts commit edef6e66e9
If you need to support the Google Play 16 kiB page size requirement, the recommendation is to use NDK r28c or newer, which automatically aligns binaries correctly.
The currently used way to determine the endianness (i.e. include
<endian.h> and use the __BYTE_ORDER macro) is provided in general by
GNU libc. Thus, extend that to any platform/OS based on GNU libc.

SDL_GetWindowFlags() also ORs in pending flags, whereas the current state is needed here, particularly when creating/showing a window.
(cherry picked from commit cd0c660dea)
In addition to hiding the border on bordered windows that will immediately become fullscreen, The combination of flags used in STYLE_BORDERLESS_WINDOWED will still show the borders on borderless windows if the initial window size exactly matches the desktop, so STYLE_BORDERLESS must be used instead.

If attempting to switch to an exclusive mode while a fullscreen spaces transition is active, wait until the transition is complete before trying to apply the changes, or the window can wind up in a weird, broken state if a mode switch occurs while in a fullscreen space.

This reverts commit 07b9e86d02.
It turns out that the problem is elsewhere, related to needing to block mode changes until spaces transitions are complete.
Discard wheel events from "Master" devices to avoid duplicates, as wheel events are stateless and can't be deduplicated.

When skipping presentation due to the window being hidden, presentDataCount is not incremented on the command buffer, and subsequently the submitted command buffers will not be cleaned up as long as the window is hidden. This results in a lag spike when showing the window due to all previously submitted command buffers suddenly being cleaned up at once, and lag at shutdown due to an equivalent number of fences needing to be destroyed.
Instead of relying on presentDataCount to determine whether a command buffer should be cleaned up, use a flag, which is set under the appropriate circumstances.

SDL_BlitSurfaceScaled could crash when passed large coordinates, due
to final_dst.w or final_dst.h getting negative values.
(cherry picked from commit 1c5c3b1479)
There may have been a reason for not attaching a null buffer when destroying a popup at some point in the past, but that is unnecessary now, as is the comment about ShowWindow crashing, as ShowWindow assures that a null buffer is attached before (re)creating the window.
(cherry picked from commit 550d95e04f)
The previous calculation could result in a window whose original position was positioned exactly corner-to-corner with the parent not being adjusted to be adjoining, and thus subject to spurious closure.

The current implementation uses the returned address of the `dlsym` function
directly to load the `environ` symbol. But this function doesn't return the
address to the symbol itself, instead it returns the address to the location
where the actual address is stored, i.e. it's an additional indirection.
Consequently, the implementation fails to load and process the environment
variables successfully.
One example where this error shows up is in the `Dialog API`: in an `X11`
environment, the `zenity` driver requires access to the user's `DISPLAY` and
`XAUTHORITY` environment variables. Because these variables aren't transfered
to the `zenity` process, no dialogs are shown. This can be exercised in the
`test/testdialog.c` testprogram.
The fix changes the indirection level of the `dlsym` call from `char **` to
`char ***`, does a `NULL`-check in case the call failed, and returns the
dereferenced actual adress to the `environ` symbol.
