3095bccd2e gtksecurememory.c: Port secure memory allocation to Windows
Use the Windows API CryptProtectMemory() to encrypt the data that we want to
secure, and use CryptUnprotectMemory() to de-crypt the secured data that we
want to access, since mmap() and mlock() are not available on Windows.

fb99bde840 Add a secure GtkEntryBuffer
We have a widget for password and passphrase entries, but we have no way
to handle the data securely. This is usually performed by a separate
GtkEntryBuffer—for instance, the one in GCR. While we have API for
setting a new entry buffer on GtkText, we don't have API for
GtkPasswordEntry, though, so the options are:

 - expose additional API for GtkPasswordEntry to allow setting a secure
   text buffer on the internal GtkText widget
 - provide a secure text buffer out of the box

Given that an insecure-by-default GtkPasswordEntry is basically
pointless, might as well have a secure buffer built in.

We don't really need to make the password entry buffer public out of the
box, but we can re-evaluate at a later date.

Fixes: #2403

c4d350c260 build: Start using meson feature options
Use feature options for things that are optional features,
update the docs.

Visible changes here is that the 'print-backends' option
got renamed to 'print' to go better with 'media', and the
'tracker3' option got renamed to 'tracker'.

For options that have been changed into features, the
syntax now is -Dfeature=enabled or -Dfeature=disabled
or -Dfeature=auto.

0d87f8cd62 a11y: Add testing API
We want to test the accessibility API, as well as the implementation
inside each widget. For that, we should expose an API that lets us
verify that a GtkAccessible has a given role, as well as a given
property.

The API follows the pattern of other GTest API:

 - a macro to assert that a condition is respected
 - a function that prints out the error message in case of failure

732578eb53 a11y: Consolidate the attributes container
While we have split the various attributes for convenience, there's no

a382dfd3bd Add GtkATContext
The ATContext type is meant to be used as the base class for
implementations of the assistive technology API—the actual mechanism
needed to communicate to components like the screen reader, or any other
AT.

Every time the widget state changes, the ATContext is meant to broadcast
the state change; and every time the AT queries the state of a UI
element, the ATContext is meant to provide that information.

We also have a "test" ATContext implementation, which is meant to be
used to write tests to verify that changes are propagated without
requiring a whole desktop session.

823ee58332 Add GtkAccessibleStateSet
Since states can be set or unset, we need a container type that has all

55120a25db Add GtkAccessibleValue
All accessible properties and states may have one of the following
types:

 - true/false
 - true/false/undefined
 - true/false/mixed/undefined
 - reference (to another UI element)
 - reference list
 - integer
 - number (real numerical value)
 - string
 - token (one of a limited set of allowed values)
 - token list

See: https://www.w3.org/WAI/PF/aria/states_and_properties#propcharacteristic_value

The GtkAccessibleValue is a simple reference counted type that can be
"subclassed" to implement each value type.

This initial commit adds GtkAccessibleValue and the basic subclasses for
plain boolean, tristate (true/false/undefined), and token types,
including statically allocated values that can be shared instead of
allocated.

14faec3ce2 Introduce GtkAccessible
GtkAccessible is an interface for accessible UI elements.

Currently, it doesn't do much except exist as a type; in the future, it
will be the entry point for all accessible state in GTK.

c63087a563 Remove ATK
To build a better world sometimes means having to tear the old one down.
        -- Alexander Pierce, "Captain America: The Winter Soldier"

ATK served us well for nearly 20 years, but the world has changed, and
GTK has changed with it. Now ATK is mostly a hindrance towards improving
the accessibility stack:

 - it maps to a very specific implementation, AT-SPI, which is Linux and
   Unix specific
 - it requires implementing the same functionality in three different
   layers of the stack: AT-SPI, ATK, and GTK
 - only GTK uses it; every other Linux and Unix toolkit and application
   talks to AT-SPI directly, including assistive technologies

Sadly, we cannot incrementally port GTK to a new accessibility stack;
since ATK insulates us entirely from the underlying implementation, we
cannot replace it piecemeal. Instead, we're going to remove everything
and then incrementally build on a clean slate:

 - add an "accessible" interface, implemented by GTK objects directly,
   which describe the accessible role and state changes for every UI
   element
 - add an "assistive technology context" to proxy a native accessibility
   API, and assign it to every widget
 - implement the AT context depending on the platform

e34c7e6796 sorter: Introduce GtkSortKeys
GtkSortKeys is an immutable struct that can be used to manage "sort
keys" for items.

Sort keys are memory that is created specifically for sorting. Because
sorting involves lots of comparisons, it's a good idea to prepare the
data relevant for sorting in advance and sort on that data.

In measurements with a PropertyExpression on a string sorter, it's about
??? faster

73fdb8f7b0 Drop GtkCoverFlow for now
There is no agreement that a coverflow widget is
appropriate for GTK 4.

It would be ok as a demo if it could live in gtk-demo,
but that requires us to make GtkListBase public first.
The demo is also somewhat rough and needs more work
to look plausible.

Drop GtkCoverFlow and the related demo for now.

2d5cf2b4c4 Drop fallback-c89.c
We require a C compiler supporting C99 now. The main purpose of
these fallbacks was for MSVC. From what I can see this is now all supported
by MSVC 2015+ anyway.

The only other change this includes is to replace isnanf() with the
(type infering) C99 isnan() macro, because MSVC doesn't provide isnanf().

66500a6882 columnview: Add sorting
This is a somewhat large commit that:

- Adds GtkColumnViewSorter
This is a special-purpose, private sorter implementation which sorts
according to multiple sorters, allowing each individual sorter to be
inverted. This will be used with clickable column view headers.

- Adds a read-only GtkColumnView::sorter property
The GtkColumnView creates a GtkColumnViewSorter at startup that it uses
for this property.

- Adds a writable GtkColumnViewColumn::sorter property
This allows defining per-column sorters. Whenever an application sets a
sorter for a column, the header becomes clickable and whenever
a header is clicked, that column's sorter is prepended to the list of
sorters, unless it is already the first sorter, in which case we invert
its order. No column can be in the list more than once.

30f09ea10b listitem: Make this a GObject
This splits GtkListItem into 2 parts:

1. GtkListItem
   This is purely a GObject with public API for developers who want to
   populate lists. There is no chance to cause conflict with GtkWidget
   properties that the list implementation assumed control over and
   defines a clear boundary.
2. GtkListItemWidget
   The widget part of the listitem. This is not only fully in control of
   the list machinery, the machinery can also use different widget
   implementations for different list widgets like I inted to for
   GtkColumnView.

7451e51619 Add GtkTreeExpander
This is a container widget that takes over all the duties of tree
expanding and collapsing.
It has to be a container so it can capture keybindings while focus is
inside the listitem.

So far, this widget does not allow interacting with it, but it shows the
expander arrow in its correct state.

Also, testlistview uses this widget now instead of implementing
expanding itself.
