In `g_data_remove_internal()`, call the `GDataElt:destroy` functions in the
order that they appear in `keys`, instead of the order that they are found in
`datalist`.
Fixes https://gitlab.gnome.org/GNOME/glib/-/issues/2672
This is more efficient than calling
g_datalist_id_remove() multiple times
in a row, since it only takes the locks
once.
Allow up to 16 keys to be removed in one go.
That is enough for the use we have in GObject,
and it avoids any danger of blowing the stack.
Add SPDX license (but not copyright) headers to all files which follow a
certain pattern in their existing non-machine-readable header comment.

The functions with a GDestroyNotify to the data, or other ill-fitting
allocation semantics, are not currently introspectable.
The effect for the binding user would be that they're unable to
create or destroy a GData list, but they might still have an API
to poke at some data pointers from it.
In fact, none of the functions dealing with GData** or a dataset
location pointer are likely to get sensible bindings anyway;
the annotations added are mostly to avoid memory unsafety
and leaks.

If we have an input parameter (or return value) we need to use (nullable).
However, if it is an (inout) or (out) parameter, (optional) is sufficient.
It looks like (nullable) could be used for everything according to the
Annotation documentation, but (optional) is more specific.
Add various (nullable) and (optional) annotations which were missing
from a variety of functions. Also port a couple of existing (allow-none)
annotations in the same files to use (nullable) and (optional) as
appropriate instead.
Secondly, add various (not nullable) annotations as needed by the new
default in gobject-introspection of marking gpointers as (nullable). See
https://bugzilla.gnome.org/show_bug.cgi?id=729660.
This includes adding some stub documentation comments for the
assertion macro error functions, which weren’t previously documented.
The new comments are purely to allow for annotations, and hence are
marked as (skip) to prevent the symbols appearing in the GIR file.

This code is used in the property notification path, so it
better be fast. This commit removes a g_return_if_fail check and
treats the common case of just a single data element better.
Also, make it possible to get a 'new ref' on a datalist member
in a race-free way.
This is useful when using object data in thread-safe libraries.

g_datalist_id_clear_i was dropping the dataset lock around
the destroy notifies, but kept the bitlock. This was causing
deadlocks when finalizing widgets.
Instead of converting the string to a quark and comparing quarks we
use the new lockless g_quark_to_string and just compare the quarks
in the datalist with the given string.
This means we avoid the global lock for string to quark. Additionally
most of the time the data list will be quite short, so the cost of
doing the sting comparisons is likely similar to that of the quark
hashtable lookup (which does at least one string comparison for a
successfull lookup).

We do this by assigning to g_quarks atomically and leaking it when
replacing it atomically. Then its safe to consume the array
on the reader side (atomically).
Also, since we're leaking quarks on growing, bump the block size
so that we're not leaking as much. gtk3-demo allocates > 1500 quarks,
and gnome apps > 3000. I'm setting the block to 2048 which means no
leaks for small gtk3 apps and just one leak for gnome apps.

This implementation uses a per-list bitlock for user data, and a
simple array rather than a linked list which uses less memory and less
allocations. It also gets better cache behaviour since related things
are stored close to each other.
