It is safe not to copy arguments here,
because we are not emitting any signals
before we are done setting the values
as properties.
This matches what we do for g_object_new now.
We can safely use the values without copying here.

None of these messages are particularly helpful, but they increase the
overall test log output size, which has to be stored by the CI for every
test run.
With these messages removed, the size of a full test log is reduced from
6.5MB to 1.8MB for me.

Modified by Philip Withnall to omit the subdirectory and drop the
`refcount` suite as both seem like unnecessary over-categorisation.
Related to issue #1434
This avoids walking the construct params list
one extra time just to count when constructing
objects, for a small speedup of object construction
in the presence of construct params.
Move the `if` into the precondition assertion, eliminating one line of
code and making the function preconditions clearer to static analysers.

Avoid GValue transformation when we can, using
the new value_is_valid vfunc.
This is particularly useful for string properties,
where g_value_transform will make a copy of the string.
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.
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.
