c09216f810 gclosure: Use (transfer floating) for closure construction functions
They return floating references, so that should be reflected in the
introspection annotations.

0ffe86a1f7 Replace most GObject warnings with criticals
All of these warnings indicate programmer error, so critical is most
appropriate here.

Exceptions: deprecation warnings are just warnings. Also, warnings that
are worded with uncertainty can remain warnings rather than criticals.

26409f19cd Add SPDX license headers for LGPL-2.1-or-later to various files
These have all been added manually, as I’ve finished all the files which
I can automatically detect.

All the license headers in this commit are for LGPL-2.1-or-later, and
all have been double-checked against the license paragraph in the file
header.

f62622fc7b docs: Start stanzas with a single paragraph
When rendering the contents of the GLib documentation stored inside the
introspection data, a common behaviour is to take the first paragraph as
a summary of the symbol being documented.

The documentation is assumed to be in Markdown format, which means:

 - paragraphs must be separated by newlines
 - lines that have an indentation of four or more spaces are considered
   code blocks
 - lines that start with a `#` are considered titles

This means we need to slightly tweak the documentation in our sources to
ensure that it can be rendered appropriately by tools that are not
gtk-doc.

9c01c1ebee gclosure: Fix the invoke() return_value annotation
The return value must be initialized by the caller, as is clear from
GLib's internal callers, and e.g. dummy_closure_marshal() on the callee
side.

00bfb3ab44 tree: Fix various typos and outdated terminology
This was mostly machine generated with the following command:
```
codespell \
    --builtin clear,rare,usage \
    --skip './po/*' --skip './.git/*' --skip './NEWS*' \
    --write-changes .
```
using the latest git version of `codespell` as per [these
instructions](https://github.com/codespell-project/codespell#user-content-updating).

Then I manually checked each change using `git add -p`, made a few
manual fixups and dropped a load of incorrect changes.

There are still some outdated or loaded terms used in GLib, mostly to do
with git branch terminology. They will need to be changed later as part
of a wider migration of git terminology.

If I’ve missed anything, please file an issue!

707106c7a5 Fix Windows build errors in valgrind.h
valgrind.h is a verbatim copy taken from Valgrind project. Previously
that file had local changes that got dropped by last update. To avoid
regressing again, do not edit valgrind.h anymore and instead add a
gvalgrind.h wrapper that gets included instead.

This fix 2 errors:
- uintptr_t is not defined when including valgrind.h on mingw.
- MSVC compiler is not supported on amd64-Win64 platform.

9cbff9f768 gclosure: Fix (transfer) annotations on GClosure constructors
They return floating references. The convention established by GVariant
is to annotate these as (transfer none) so that the caller does a
ref+sink on them, rather than just a ref.

18a33f72db introspection: use (nullable) or (optional) instead of (allow-none)
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.

25a7c817d3 glib: Add missing (nullable) and (optional) annotations
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.

69fd1fd1d0 GClosure: add valgrind hints
GClosure has been in the "allocate area before the pointer" game since
before we did this with GTypeInstance.  At the time that this was done
for GClosure, we didn't have valgrind.h in GLib.

Now that we do, we should add similar valgrind hints as the ones we did
for GTypeInstance.  This substantially reduces reports of "possibly
lost" on pretty much any program that makes use of signals.

d5fbbe400a Add GRealClosure and move meta_marshallers there
This means we're not abusing the notifiers for meta_marshallres,
and we're able to later cleanly add other fields to GClosure.

We still have to leave the ABI intact for the GClosure->meta_marshal
bit, as old G_CLOSURE_N_NOTIFIERS macro instances still accesses it.
However, we always set it to zero to keep those macros working.
