Downstream distributors can use this to mark a version with their
preferred version information, like a Linux distribution package version
or the Steam revision it was built to be bundled into, or just to mark
it with the vendor it was built by or the environment it's intended to
be used in.
For instance, in Debian I'd use this by configuring with:
--enable-vendor-info="${DEB_VENDOR} ${DEB_VERSION}"
to get a SDL_REVISION like:
release-2.24.1-0-ga1d1946dc (Debian 2.24.1+dfsg-2)
which gives a Debian user enough information to track down the patches
and build-time configuration that were used for package revision 2.
In Autotools and CMake, this is a configure-time option like any other,
and will go into both SDL_REVISION (via SDL_revision.h) and
SDL_GetRevision().
In other build systems (MSVC, Xcode, etc.), defining the
SDL_VENDOR_INFO macro will get it into the output of SDL_GetRevision(),
although not SDL_REVISION.

Instead of using a URL and git sha1, this uses `git describe` to
describe the version relative to the nearest previous git tag, which
gives a better indication of whether this is a release, a prerelease,
a slightly patched prerelease, or a long way after the last release
during active development.
This serves two purposes: it makes those APIs more informative, and it
also puts this information into the binary in a form that is easy to
screen-scrape using strings(1). For instance, if the bundled version of
SDL in a game has this, we can see at a glance what version it is.
It's also shorter than using the web address of the origin git
repository and the full git commit sha1.
Also write the computed version into a file ./VERSION in `make dist`
tarballs, so that when we build from a tarball on a system that doesn't
have git available, we still get the version details.
For the Perforce code path in showrev.sh, output the version number
followed by the Perforce revision, in a format reminiscent of
`git describe` (with p instead of g to indicate Perforce).
For the code path with no VCS available at all, put a suffix on the
version number to indicate that this is just a guess (we can't know
whether this SDL version is actually a git snapshot or has been
patched locally or similar).

Disabling RAWINPUT on Windows 10 causes these issues:
* All Xbox controllers are named "XInput Controller".
* Trigger rumble no longer works.
* "XInput Controllers" are now also listed as separate haptic devices
It's only needed to support more than 4 Xbox controllers, and adds significant complexity to the joystick processing, and we regularly get bugs from people who aren't using an SDL window who need to turn on SDL_HINT_JOYSTICK_THREAD.
* Consolidated scancode mapping tables into a single location for all backends
* Verified that the xfree86_scancode_table2 is largely identical to the Linux scancode table
* Updated the Linux scancode table with the latest kernel keycodes (still unmapped)
* Route X11 keysym -> scancode mapping through the linux scancode table (which a few hand-written exceptions), which will allow mappings to automatically get picked up as they are added in the Linux scancode table
* Disabled verbose reporting of missing keysym mappings, we have enough data for now
Several games (including Source and GoldSrc games, and Bioshock
Infinite) attempt to "fake" relative mouse mode by repeatedly warping
the cursor to the centre of the screen. Since mouse warping is not
supported under Wayland, the viewport ends up "stuck" in a rectangular
area.
Detect this case (mouse warp while the cursor is not visible), and
enable relative mouse mode, which tracks the cursor position
independently, and so can Warp successfully.
This is behind the SDL_HINT_VIDEO_WAYLAND_EMULATE_MOUSE_WARP hint, which
is enabled by default, unless the application enables relative mouse
mode itself using SDL_SetRelativeMouseMode(SDL_TRUE).
Note that there is a behavoural difference, in that relative mouse mode
typically doesn't take mouse accelleration into account, but the
repeated-warping technique does, so mouse movement can seem very slow
with this (unless the game has its own mouse accelleration option, such
as in Portal 2).
* Added support for vertical mode for Joy-Con controllers
* Added the hint SDL_HINT_JOYSTICK_HIDAPI_VERTICAL_JOY_CONS for switching to this mode
* Added support for SL/SR buttons in combined/vertical mode and L/ZL/R/ZR buttons in mini-gamepad mode
