Call chain:
- input_data_cb
- broadway_server_read_all_input_nonblocking (input)
- broadway_input_free (input)
(now input is invalid)
attempt to use input->active -> use-after-free
Make broadway_server_read_all_input_nonblocking return a boolean, TRUE
if the input was valid, FALSE otherwise. This allows input_data_cb to
detect whether the input was gone or not.

GdkKeymap already has support for _get_num_lock_state() and
_get_caps_lock_state(). Adding _get_scroll_lock_state() would be good
for completness and some backends (Windows?) could take advantage of
this.
It seems that posix_fallocate gives an ENODEV error when
called on an fd opened with shm_open on freebsd. Fix up
the error check to only trigger if we get ENOSPC.

In various places, the broadway backend was just using
the default display and assumed that it is the broadway
display. That may not be the case in a multi-backend world,
so instead iterate over all displays and use the first
broadway display - still not perfect, but enough to survive
for now.
The current implementation of this script generate headers with \x-escaped
strings that can become too long (> 65535 characters) for Visual Studio
to consume, hence the build of broadwayd would break on Visual Studio.
This changes the script to instead format the string as an array of hex
characters, not unlike what GResource does, so that builds can continue as
normal on Visual Studio builds as well.

Remove checks for NULL before g_free() and g_clear_object().
Merge check for NULL, freeing of pointer and its setting
to NULL by g_clear_pointer().

At the present time broadway listens only for TCP/IP incoming
display connections. This patch implements the support for listening
on unix domain sockets too, adding the broadway_server_on_unix_socket_new()
constructor and the commandline option --unixsocket [path] to broadwayd.

Traditionally, the way painting was done in GTK+ was with the
"expose-event" handler, where you'd use GDK methods to do drawing on
your surface. In GTK+ 2.24, we added cairo support with gdk_cairo_create,
so you could paint your graphics with cairo.
Since then, we've added client-side windows, double buffering, the paint
clock, and various other enhancements, and the modern way to do drawing
is to connect to the "draw" signal on GtkWidget, which hands you a
cairo_t. To do double-buffering, the cairo_t we hand you is actually on
a secret surface, not the actual backing store of the window, and when
the draw handler completes we blit it into the main backing store
atomically.
The code to do this is with the APIs gdk_window_begin_paint_region,
which creates the temporary surface, and gdk_window_end_paint which
blits it back into the backing store. GTK+'s implementation of the
"draw" signal uses these APIs.
We've always sort-of supported people calling gdk_cairo_create
"outside" of a begin_paint / end_paint like old times, but then you're
not getting the benefit of double-buffering, and it's harder for GDK to
optimize.
Additionally, newer backends like Mir and Wayland can't actually support
this model, since they're based on double-buffering and swapping buffers
at various points in time. If we hand you a random cairo_t, we have no
idea when is a good time to swap.
Remove support for this.
This is technically a GDK API break: a warning is added in cases where
gdk_cairo_create is called outside of a paint cycle, and the returned
surface is a dummy that won't ever be composited back onto the main
surface. Testing with complex applications like Ardour didn't produce
any warnings.
It seems that some backends implemented get_root_origin wrong
and returned the client window coordinates, not the frame window
coordinates. Since it's possible to implement generically for all
windows, let's do that instead of having a separate impl vfunc.
eb1ab0dac2 removed support for authentication
based on crypt()-hashed passwords but it didn't remove the header.
Finish up with the removal.
This allows the broadway backend to build on FreeBSD (which has no
crypt.h).

Instead of destroying the surface in the backend if this is
unable to resize, let the core code do it, and do it properly.

We add a custom im module for broadway that calls some broadway
specific APIs to show/hide the keyboard on focus in/out. We then forward this
to the browser, and on the ipad we focus an input field to activate
the keyboard.
The broadway backend would move the focus from one window to another based on
where the mouse was (i.e. 'focus-follows-mouse' approach). Handling the focus
this wait didn't play well with widgets which rely on focus-in-event and
focus-out-event, like the GtkEntry when using a completion popup window, see
e.g:
https://bugzilla.gnome.org/show_bug.cgi?id=708984
So instead, setup broadway to require a click in a window to move the focus
(i.e. 'click-to-focus' approach):
* The implicit GDK_FOCUS_CHANGE events that were generated upon reception of
BROADWAY_EVENT_ENTER or BROADWAY_EVENT_LEAVE are removed.
* The broadway daemon will now keep track of which is the focused window
* Whenever the daemon detects an incoming BROADWAY_EVENT_BUTTON_PRESS, it will
trigger the focused window switch, which sends a new BROADWAY_EVENT_FOCUS to
the client, specifying which windows holds the focus.
* Upon reception of a BROADWAY_EVENT_FOCUS, the client will generate a new
GDK_FOCUS_CHANGE.
* gdk_broadway_window_focus() was also implemented, which now requests the
focus to the broadway server using a new BROADWAY_REQUEST_FOCUS_WINDOW.
This is based on an initial patch from Aleksander Morgado <aleksander@lanedo.com>.
If a motion event handler (or other handler running from the flush-events
phase of the frame clock) recursed the main loop then flushing wouldn't
complete until after the recursed main loop returned, and various aspects
of the state would get out of sync.
To fix this, change flushing of the event queue to simply mark events as
ready to flush, and let normal event delivery handle the rest.
