With the exception of gtk_buildable_get_id(), those are only used
to construct objects from XML descriptions, which is functionality
internal to GTK.
The API is therefore unlikely to be missed, and keeping it internal
means they can no longer unintentionally shadow object methods in
bindings with less namespacing; for example it's currently ambiguous
whether `infoBar.add_child()` refers to gtk_info_bar_add_child() or
gtk_buildable_add_child().

<lookup>foo</lookup>
is now short for
<lookup>
<constant>foo</constant>
</lookup>
ie it looks up the object with the given name so it can then do a
property lookup with it.
This is the most common operation, so it's a nice shortcut.
A constant without a type is assumed to be an object. This is the most
common case and allows
<constant>foo</constant>
without requiring updates to the type whenever the foo object changes.
Sprinkle various g_assert() around the code where gcc cannot figure out
on its own that a variable is not NULL and too much refactoring would be
needed to make it do that.
Also fix usage of g_assert_nonnull(x) to use g_assert(x) because the
first is not marked as G_GNUC_NORETURN because of course GTester
supports not aborting on aborts.
These don't take a duration, instead they call g_get_monotonic_time() to
and subtract the start time for it.
Almost all our calls are like this, and this makes the callsites clearer
and avoids inlining the clock call into the call site.
usec is the scale of the monotonic timer which is where we get almost
all the times from. The only actual source of nsec is the opengl
GPU time (but who knows what the actual resulution of that is).
Changing this to usec allows us to get rid of " * 1000" in a *lot* of
places all over the codebase, which are ugly and confusing.
... and use it. This function looks up an object like
gtk_builder_get_object() but generates an error on failure.
Unlike the evil function _gtk_builder_lookup_object() which also
generates an error but hides it for later lookup.
Use this to avoid continuing applying properties when an error was
encountered.
- Propagate the error back to the parser, so we get a proper GError
instead of a g_warning().
- Connect closures by id, don't construct a name from the ids so that
glib can take it apart again.
This currenly just wraps GMarkupParser, but the plan is to expose this
instead of GMarkup in the GtkBuildable interfaces, allowing us to
replace the parser with something that handles pre-parsed input
instead.
Note that we duplicate some of the features of GMarkup to implement
the APIs rather then call down to GMarkup, as we need to support these
in the pre-parsed case anyway.
In addition to <property name="foo">bar</property> referring
to an object with ID bar, we now also parse
<property name="foo"><object>...
to specify a property 'inline'.
The typical UI file has a lot more <property> tags than it has
<requested> or <interface> tags, etc. so order the string comparisons
according to this expected case.
The g_print documentation explicitly says not to do this, since
g_print is meant to be redirected by applications. Instead use
g_message for logging that can be triggered via GTK_DEBUG.
Add the class and parent class name to the error message.
gtk-builder-tool will parse the error message and use the
class names for trying again to parse the file as a template.
