Generated XXX_is_valid() functions for enums are guarded behind the
same #define as the enum itself. This worked fine until recently,
but since fbd7460737c9 ("scanner: add new enum-header mode") we're
also generating enum-only headers.
When including the enum-only header first, and then the server
header, the validator functions are missing.
Define a separate guard to fix this.

Bitfields are valid if the value only contains bits inside of

Right now compositors need to manually check that enum values sent
by the client are valid. In particular:
- Check that the value sent by the client is not outside of the enum.
- Check that the version of the enum entry is consistent with the
object version.
Automatically generate validator functions to perform these tasks.

If a wl_array has size zero, wl_array_for_each computes NULL + 0 to get
to the end pointer. This should be fine, and indeed it would be fine in
C++. But the C specification has a mistake here and it is actually
undefined behavior. See
https://davidben.net/2024/01/15/empty-slices.html
Clang's -fsanitize=undefined flags this. I ran into this in Chromium's
build with wayland-scanner on one of our XML files.
../../third_party/wayland/src/src/scanner.c:1853:2: runtime error: applying zero offset to null pointer

An empty XML file is sufficient to hit this case, so I've added it as a
test. To reproduce, undo the fix and include only the test, then build
with:
CC=clang CFLAGS="-fno-sanitize-recover=undefined" meson build/ -Db_sanitize=undefined -Db_lundef=false
ninja -C build test

This adds a command to re-generate the test data. This needs to be
done when either an XML source file or the scanner's output is
changed.

Use the new flagged marshal+destroy function in generated code.
It's intended as a replacement for all existing wl_proxy_marshal_*
functions, so I've used it to replace them all. This results in a large
update to the scanner test files as well.
We now pass the new WL_MARSHAL_FLAG_DESTROY flag when appropriate, so
the race condition in #86 caused by releasing the display mutex between
marshalling the proxy and destroying the proxy is now gone.
Fixes #86

This is the style used in wayland.xml which is the only file we really
care about for git blame information. So let's adjust all others to that
style for consistency and fix editorconfig to avoid messing this up in
the future.

When doing unity builds via meson (example project:
https://github.com/swaywm/sway) multiple source files are glued together
via #include directives. Having every wayland-scanner generated source
file have an identifier named '*types[]' will lead to errors in these
unity builds if two or more of these are joined.

The test runs wayland_scanner on a set of XML protocol files which
have malformed element names, and confirms that an error is produced
and indicates the correct line.
Copyright notifications are not included in the test files, as
they are not code; of course, the project license still applies.

Unlike a wheel rotation, a wheel tilt is a discrete-only axis. Wheel rotations
are mapped to degrees in libinput but that that does not apply to wheel tilt
axes where there is no physical equivalent.

This was already in the DTD but not supported by the scanner.
The check for ever-increasing "since" tags is not strictly required for enum
entries as we control the binary value. But it keeps the xml file in
good order, preventing things like:
<entry name="first" value="…" />
<entry name="second" value="…" since="3"/>
<entry name="third" value="…" since="2"/>
<entry name="fourth" value="…" since="3"/>
If this is undesirable in the future the check can be removed without
side-effects.

This patch adds the input and reference output data files for the
wayland-scanner tests to be added by the following patch.
The data files are split into their own patch because they are extremely
uninteresting to review:
- example.xml is just a copy wayland.xml from 1.12.0
- small.xml is a tiny dummy definition used for testing scanner
variations without causing lots of big output files
- the other files are wayland-scanner products from the xml files
