443cb14d6e Assume non-NULL serial in file_handler
The previous commit guarantees to always initialize the serial, so the
file_handle may assume it is never NULL.

b30c3a429f Always retrieve device serial
This allows to execute all adb commands with the specific -s parameter,
even if it is not provided by the user.

In practice, calling adb without -s works if there is exactly one device
connected. But some adb commands (for example "adb push" on drag & drop)
could be executed after another device is connected, so the actual
device serial must be known.

632bd5697b Add missing error handling

de50846905 Close process on check success
The interruptible version of the function to check process success
(sc_process_check_success_intr()) did not accept a close parameter to
avoid a race condition. But as the result, the processes were not closed
at all.

Add a close parameter, and close the process separately to avoid the
race condition.

cc0902b13c Read/write settings via command on Android >= 12
Before Android 8, executing the "settings" command from a shell was
very slow (~1 second), because it spawned a new app_process to execute
Java code. Therefore, to access settings without performance issues,
scrcpy used private APIs to read from and write to settings.

However, since Android 12, this is not possible anymore, due to
permissions changes.

To make it work again, execute the "settings" command on Android 12 (or
on previous version if the other method failed). This method is faster
than before Android 8 (~100ms).

94feae71f2 Report settings errors via Exceptions
Settings read/write errors were silently ignored. Report them via a
SettingsException so that the caller can handle them.

This allows to log a proper error message, and will also allow to
fallback to a different settings method in case of failure.

67170437f1 Wrap settings management into a Settings class
Until now, the code that needed to read/write the Android settings had
to explicitly open and close a ContentProvider.

Wrap these details into a Settings class.

This paves the way to provide an alternative implementation of settings
read/write for Android >= 12.

9cb14b5166 Inherit only specific handles on Windows
To be able to communicate with a child process via stdin, stdout and
stderr, the CreateProcess() parameter bInheritHandles must be set to
TRUE. But this causes *all* handles to be inherited, including sockets.

As a result, the server socket was inherited by the process running adb
to execute the server on the device, so it could not be closed properly,
causing other scrcpy instances to fail.

To fix the issue, use an extended API to explicitly set the HANDLEs to
inherit:
