Sadly, this detection was broken because in C everything defaults to
type int. Casting a const char* to int is permitted but generates a
warning which was promptly ignored by meson.
This result in HAVE_C23_AUTO being set on compilers that don't by
default have -Werror=implicit-int and "auto" ended up being just an
"int".
Change the detection to use gmtime() which returns a struct, and add a
basic test using one of our struct-returning utility functions, just to
be sure.

A set of macros that expand to different things depending on the
number of arguments passed into the macro. Can be used for anything
but in the test case we use it to differ between stringifying the single
argument or taking a custom string for that same argument.

The previous test was prone to a race condition if multiple tests were
run in parallel: since we're using a udev context here we would see any
device added through uinput. If the DEVICE_ADDED event was from a
device added by some other test we would later fail the test because
that other device still used the default seat.
Rewrite it to use a name comparison and in the process start using the
cleanup macros.

Taken from libei, with slight modifications. The general approach is:
basic data types use _autofoo_ to call the maching foo function on
cleanup. Struct types use _unref_, _destory_, _free_, whichever applies
to that struct.
Notably: attribute syntax depends on where it's declared [1] so in the
following examles only a, b, and d have the autofree attribute:
_autofree_ char *a, *b;
char *c, _autofree *d;
Simplest way to ensure it's all correct to keep the declarations one per
line.

If we push/pop event frames and combine various functions we might end
up sending the same value in the same frame multiple times. This
*should* be fine with libinput but is different to what the kernel does
in that case and harder to debug.
Let's batch any litest_event() until an EV_SYN arrives, then write them
all to libinput in one go.

When running several tests simply having the list of failed test names
is not very convenient. The actual error may be thousands of lines north
and worse, meson only prints the last 100 lines of a test log by default.
So let's print the full test data including backtrace etc. at the end
instead.

These are all internal API so having a NONE value means we can shut up
warnings about 0 not being an enum value without having those exposed in
our public API.
And they slightly improve readability in the callers anyway.

In a valiant approach to introduce some type-safety (after spending time
debugging a int vs double confusion) this adds a DECLARE_NEWTYPE()
macro that declares a named struct with a single typed value field.
This is basically the C version of Rusts "struct Foo(u32)" with
a few accessors auto-generated by the macro.
C is happy to silently convert between base types but it doesn't do
so for structs so this allows us to have some type safety
when we accidentally assign two incompatible fields to each other (e.g.
an axis value in device units vs a percentage value).

Instead of having this ifdef'd out split the main and directly
associated functions out into a separate file.
That ifdef used to exist so we can use parts of litest in some other
files (the selftest and the utils test). Those tests care mostly
about the assertion helpers so long-term a split into
assert helpers and "rest of litest" would be better. For now, this will
do.
