f6320c7e31 Wrap SDL thread functions into scrcpy-specific API
The goal is to expose a consistent API for system tools, and paves the
way to make the "core" independant of SDL in the future.

30e619d37f Replace SDL_strdup() by strdup()

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'

b8edcf52b0 Simplify process_wait()
The function process_wait() returned a bool (true if the process
terminated successfully) and provided the exit code via an output
parameter exit_code.

But the returned value was always equivalent to exit_code == 0, so just
return the exit code instead.

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.

904d470579 Pause on error from a wrapper script
On Windows, scrcpy paused on error before exiting to give the user a

This was a hack and causes issues when using scrcpy from batch scripts.

Disable this pause from the scrcpy binary, and provide a batch wrapper
(scrcpy-console.bat) to pause on error.

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.

dcde578a50 Reactivate "turn device screen on" feature
This reverts commit 8c8649cfcd.

I cannot reproduce the issue with Ctrl+Shift+o on any device, so in
practice it works, it's too bad to remove the feature for a random bug
on some Android versions on some devices.

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.

a3ef461d73 Add cli option to set the verbosity level
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
logs using the release:

    scrcpy -Vdebug

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.

080a4ee365 Add --codec-options
Add a command-line parameter to pass custom options to the device
encoder (as a comma-separated list of "key[:type]=value").

The list of possible codec options is available in the Android
documentation:

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.

fae3f9eeab Remove warning when renderer is not OpenGL
Trilinear filtering can currently only be enabled for OpenGL renderers.

Do not print a warning if the renderer is not OpenGL, as it can confuses
users, while nothing is wrong.

f5aeecbc62 Reset window size on initialization
On macOS with renderer "metal", HiDPI scaling may be incorrect on
initialization when several displays are connected.

Resetting the window size fixes the problem.

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).

d860ad48e6 Extract optimal window size detection
Extract the computation to detect whether the current size of the window
is already optimal.

This will allow to reuse it for rendering.

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.
