In constrast to value_validate, this one does not
modify the passed-in value, so we can avoid the cost
of copying the GValue beforehand.
It is optional, but we set it for most of the
builtin pspec types.
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.
In several places we do paired calls of g_value_init
and g_value_unset, both of which peek the value table.
We can avoid half of that cost by remembering the value
table, instead of looking it up again.
This uses the new G_VALUE_COLLECT_INIT2 macro.
The user data parameters in callbacks need to be named user_data to
generate correct closure attributes in the introspection data. This
updates parameters missed in GNOME/glib!2633.
As noticed by Christian Hergert: We can reduce
some overhead by checking for exact type
equality first. According to Christian, around
3% of g_type_is_a calls are exact equalities.
Using prefixed property names like GtkWidget::visible
is very deprectated and basically never done. So avoid
paying the strchr cost before doing the first lookup.
Most of the time, we are dealing with static strings,
and we can compare them directly and avoid the strcmp.
Note that triggering this optimization requires
properties to be marked as G_PARAM_STATIC_NAME.
Drop the redundant `PROP_0` (which isn’t a real property) and initialise
the first member of the enum instead.
Add a typedef so that the enum type can be used in `switch` statements
in `get_property()` and `set_property()` vfuncs. This allows
`-Wswitch-enum` to be used to improve type safety.
The examples here don’t have `get_property()` or `set_property()`
vfuncs, but people might copy/paste the code to somewhere which does.

Make it a bit clearer in the documentation that using
`G_PARAM_STATIC_STRINGS` everywhere is a good thing.

They are lists of keywords, and don’t contain original copyrightable
content.
This can’t be indicated by a copyright header inside the files, as the
format doesn’t easily allow for that.

The files have only been touched by a subset of three people: pdknsk,
Philip Withnall, and Marc-André Lureau. Their copyrights are assigned to
pdknsk, Endless OS Foundation and Red Hat.
The default license for GLib at the time of writing these files was (and
still is) LGPL-2.1-or-later.
`driver.c` came from LLVM and is under a different license:
https://github.com/llvm/llvm-project/blob/main/compiler-rt/lib/fuzzer/standalone/StandaloneFuzzTargetMain.c.
That doesn’t affect the license of GLib overall, since it’s only used
for testing during development.

These files are Markdown-ified versions of the following wiki pages:
* https://wiki.gnome.org/Projects/GLib/CompilerRequirements
* https://wiki.gnome.org/Projects/GLib/SupportedPlatforms
Keeping the files in version control with the rest of the documentation
means they should be easier to find, and easier to remember to keep up
to date.
They have not been modified other than to change to Markdown and tweak
the formatting. Content updates to them will be done in future commits.
