c0c4ba7009 Add intermediate frame in video buffer
There were only two frames simultaneously:
 - one used by the decoder;
 - one used by the renderer.

When the decoder finished decoding a frame, it swapped it with the
rendering frame.

Adding a third frame provides several benefits:
 - the decoder do not have to wait for the renderer to release the
   mutex;
 - it simplifies the video_buffer API;
 - it makes the rendering frame valid until the next call to
   video_buffer_take_rendering_frame(), which will be useful for
   swscaling on window resize.

97b001e7c0 Fix undefined left shift
Small unsigned integers promote to signed int. As a consequence, if v is
a uint8_t, then (v << 24) yields an int, so the left shift is undefined
if the MSB is 1.

Cast to uint32_t to yield an unsigned value.

Reported by USAN (meson x -Db_sanitize=undefined):

    runtime error: left shift of 255 by 24 places cannot be represented
    in type 'int'

d580ee30f1 Separate process wait and close
On Linux, waitpid() both waits for the process to terminate and reaps it
(closes its handle). On Windows, these actions are separated into
WaitForSingleObject() and CloseHandle().

Expose these actions separately, so that it is possible to send a signal
to a process while waiting for its termination without race condition.

This allows to wait for server termination normally, but kill the
process without race condition if it is not terminated after some delay.

10b749e27d Kill the server only after a small delay
Let the server terminate properly once all the sockets are closed.

If it does not terminate (this can happen if the device is asleep), then
kill it.

Note: since the server process termination is detected by a flag set
after waitpid() returns, there is a small chance that the process
terminates (and the PID assigned to a new process) before the flag is
set but before the kill() call. This race condition already existed
before this commit.

e8a565f9ea Fix touch events HiDPI-scaling
Touch events were HiDPI-scaled twice:
 - once because the position (provided as floats between 0 and 1) were
   converted in pixels using the drawable size (not the window size)
 - once due to screen_convert_to_frame_coords()

One possible fix could be to compute the position in pixels from the
window size instead, but this would unnecessarily round the event
position to the nearest window coordinates (instead of drawable
coordinates).

Instead, expose two separate functions to convert to frame coordinates
from either window or drawable coordinates.

fc1dec0270 Paste on "set clipboard" if possible
Ctrl+Shift+v synchronizes the computer clipboard to the Android device
clipboard. This feature had been added to provide a way to copy UTF-8
text from the computer to the device.

To make such a paste more straightforward, if the device runs at least
Android 7, also send a PASTE keycode to paste immediately.

274b591d18 Fix union typo
The "set clipboard" event used the wrong union type to store its text.

In practice, it worked because both are at the same offset.

8f46e18426 Add --force-adb-forward
Add a command-line option to force "adb forward", without attempting
"adb reverse" first.

This is especially useful for using SSH tunnels without enabling remote
port forwarding.

The verbosity was set either to info (in release mode) or debug (in
debug mode).

Add a command-line argument to change it, so that users can enable debug

56bff2f718 Avoid compiler warning
The field lock_video_orientation may only take values between -1 and 3
(included). But the compiler may trigger a warning on the sprintf()
call, because its type could represent values which could overflow the
string (like "-128"):

> warning: ‘%i’ directive writing between 1 and 4 bytes into a region of
> size 3 [-Wformat-overflow=]

Increase the buffer size to remove the warning.

ac4c8b4a3f Increase LOD bias for mipmapping
Mipmapping caused too much blurring.

Using a LOD bias of -1 instead of -0.5 seems a better compromise to
avoid low-quality downscaling while keeping sharp edges in any case.

f5aeecbc62 Reset window size on initialization

e40532a376 Manually position and scale the content
Position and scale the content "manually" instead of relying on the
renderer "logical size".

This avoids possible rounding differences between the computed window
size and the content size, causing one row or column of black pixels on
the bottom or on the right.

This also avoids HiDPI scale issues, by computing the scaling manually.

This will also enable to draw items at their expected size on the screen
(unscaled).

ec047b501e Disable "resize to fit" in maximized state
In maximized state (but not fullscreen), it was possible to resize to
fit the device screen (with Ctrl+x or double-clicking on black borders).

This caused problems on macOS with the "expand to fullscreen" feature,
which behaves like a fullscreen mode but is seen as maximized by SDL.
In that state, resizing to fit causes unexpected results.

To keep the behavior consistent on all platforms, just disable "resize
to fit" when the window is maximized.

4c2e10fd74 Workaround maximized+fullscreen on Windows
On Windows, in maximized+fullscreen state, disabling fullscreen mode
unexpectedly triggers the "restored" then "maximized" events, leaving
the window in a weird state (maximized according to the events, but not
maximized visually).

Moreover, apply_pending_resize() asserts that fullscreen is disabled.

To avoid the issue, if fullscreen is set, just ignore the "restored"
event.

6b1da2fcff Simplify size changes in fullscreen or maximized
If the content size changes (due to rotation for example) while the
window is maximized or fullscreen, the resize must be applied once
fullscreen and maximized are disabled.

The previous strategy consisted in storing the windowed size, computing
the target size on rotation, and applying it on window restoration. But
tracking the windowed size (while ignoring the non-windowed size) was
tricky, due to unspecified order of SDL events (e.g. size changes can be
notified before "maximized" events), race conditions when reading window
flags, different behaviors on different platforms...

To simplify the whole resize management, store the old content size (the
frame size, possibly rotated) when it changes while the window is
maximized or fullscreen, so that the new optimal size can be computed on
window restoration.
