Uli Schlachter 734b541ecd Map between X11 Windows and WlSurfaces
Xwayland gives us a mapping between X11 window and WlSurface IDs via
special WL_SURFACE_ID messages. This commit uses these messages to find
the corresponding WlSurface. For this, the new client.get_resource API
from wayland-server is needed.

Uli Schlachter df01587459 Become the X11 window manager after Xwayland startup
This commits adds the necessary magic incantations to become the X11 WM
after Xwayland starts.

This uses the pure-Rust implementation from x11rb, but any other X11
crate could be used as well.

Uli Schlachter 2f0dadd6ca anvil: Add a xwayland feature
This commit adds an xwayland feature to anvil. Right now, this feature
doesn't do much. anvil uses the smithay code to start XWayland, but does
not do anything with it once it is running.

Uli Schlachter a7f18e5deb winit: Allow moving the cursor
It is not necessary to set the cursor position on winit since the
windowing system already updates the position on its own. Instead, doing
this makes the cursor (almost) stuck and unmovable. Thus, this commit
just removes that code from the winit backend.

XWayland: Use a fork helper process to launch Xwayland (#250)
* xwayland: Add LaunchHelper

Calling fork() in a multi-threaded process is a bad idea. I am getting
crashes at exit() and "man fork" says that only async-signal-safe
functions can be called after forking in a multi-threaded process.
exit() is not async-signal safe. Thus, forking needs to happen before
any threads are created.

This commit adds a LaunchHelper to the public API. This is a handle to a
forked child process. So far this does not do much, but the intention is
to use this later instead of fork()ing directly.

* xwayland: Move the fork dance to LaunchHelper

No functional changes intended. This only moves the code over and does
not actually use the LaunchHelper for anything.

Signed-off-by: Uli Schlachter <psychon@znc.in>

* Move checking the launch status to LaunchHelper

This should again have no functional changes, but the error log output
might change slightly, since an IOError instead of a NixError is
returned.

* xwayland: Set $DISPLAY earlier

This way, the WM already gets the correct value of $DISPLAY.

* xwayland: Use the launch helper process

FD passing is now used to give the display number and the sockets to the
launch helper process. That process then forks of the actual process
that spawns Xwayland. Once Xwayland started, this is reported back with
another write on the pipe.

Uli Schlachter 06c44ede55 xwayland: Unlink X11 socket before binding to it
When starting xwayland with smithay, the first time I would get the
following output (do not ask what happens with displays 0, 1, 2. That's
not important right now):

Dec 29 14:13:31.031 DEBG Attempting to aquire an X11 display lock, D: 3, smithay_module: XWayland
Dec 29 14:13:31.032 DEBG X11 lock aquired, D: 3, smithay_module: XWayland
Dec 29 14:13:31.032 INFO Initialization completed, starting the main loop.

When killing the process with ctrl-c and starting it again, this
happened:

Dec 29 14:13:29.138 DEBG Attempting to aquire an X11 display lock, D: 3, smithay_module: XWayland
Dec 29 14:13:29.138 DEBG Failed to acquire lock, D: 3, smithay_module: XWayland

Dec 29 14:13:29.139 DEBG X11 lock aquired, D: 4, smithay_module: XWayland
Dec 29 14:13:29.139 INFO Initialization completed, starting the main loop.

The reason for the above behaviour is the
smithay::xwayland::x11_sockets::open_x11_sockets_for_display() failed.
The code successfully acquired the lock file, but then could not bind
the sockets. More specifically, the concrete socket in /tmp/.X11-unix/
already existed and thus bind() failed with EADDRINUSE.

(The code in X11Lock::grab() would then drop the already acquired
X11Lock and its Drop impl deleted the socket. Thus, when I started
things again, this time it successfully acquired display 3.)

Fix this removing the socket before trying to bind it.

This is also done by wlroots: In xwayland/sockets.x, the function
open_socket() has the same job as smithay's open_socket() function.
However, for non-abstract sockets, it would first unlink the target
before trying to bind:

        if (addr->sun_path[0]) {
                unlink(addr->sun_path);
        }

Uli Schlachter 9e14e43bd8 Fix writing /tmp/.X{}.lock
Here is a lock file not created by smithay:

$ xxd /tmp/.X0-lock
00000000: 2020 2020 2020 2035 3537 0a                     557.

And this is a lock file created by smithay:

$ xxd /tmp/.X23-lock
00000000: 2020 2020 3130 3733 3332                     107332

As you see, the difference is a trailing newline (0x0a).

Lock files 1 to 22 where also created by smithay, because I started it a
couple of times. Reading these lock files fails, since the code expects
a file with at least 11 bytes of content: It uses read_exact() with a
buffer of length 11 in the Err()-branch of the match that this commit
modifies.

Uli Schlachter e427787353 xwayland: Use pipe instead of signal
Handling SIGUSR1 requires setting a signal handler, which is a global
resource. This can also cause problems in the presence of threads, since
every thread needs to set up a signal handler. This commit instead
changes the code to use a pipe instead (actually a UnixStream). When the
child closes the pipe, the parent wakes up and knows "to do something".

Victor Berger 49dda88c63 backend.input: keep sub-pixel precision in events
libinput provides sub-pixel precision for pointer motion & touch events.
Keep this precision by switching all coordinates values from input
events to f64 (rather than i32 or u32). Otherwise, values are rounded
and part of the movment is lost.
