57056d078d Use precise scrolling values
Since SDL 2.0.18, the amount scrolled horizontally or vertically is
exposed as a float (between 0 and 1). Forward a precise value to the
Android device when possible.

6a4a4a283d Remove obsolete alternative injection method
The previous commit replaced the IInterface instance (the "input"
service) by the InputManager instance (retrieved by
InputManager.getInstance()).

Both define an "injectInputEvent" method, but the alternate version
(probably) does not concern the InputManager.

This reverts commit b7a06278fe.

c0a75ca746 Downscale and retry also on early MediaCodec error
The new retry mechanism with a lower definition only worked if the error
occurred during encode(). For example:

    java.lang.IllegalStateException
        at android.media.MediaCodec.native_dequeueOutputBuffer(Native Method)
        at android.media.MediaCodec.dequeueOutputBuffer(MediaCodec.java:3452)
        at com.genymobile.scrcpy.ScreenEncoder.encode(ScreenEncoder.java:114)
        at com.genymobile.scrcpy.ScreenEncoder.internalStreamScreen(ScreenEncoder.java:95)
        at com.genymobile.scrcpy.ScreenEncoder.streamScreen(ScreenEncoder.java:61)
        at com.genymobile.scrcpy.Server.scrcpy(Server.java:80)
        at com.genymobile.scrcpy.Server.main(Server.java:255)

However, MediaCodec may also fail before encoding, during configure() or
start(). For example:

    android.media.MediaCodec$CodecException: Error 0xfffffc0e
        at android.media.MediaCodec.native_configure(Native Method)
        at android.media.MediaCodec.configure(MediaCodec.java:1956)
        at android.media.MediaCodec.configure(MediaCodec.java:1885)
        at com.genymobile.scrcpy.ScreenEncoder.configure(ScreenEncoder.java:158)
        at com.genymobile.scrcpy.ScreenEncoder.streamScreen(ScreenEncoder.java:68)
        at com.genymobile.scrcpy.Server.scrcpy(Server.java:28)
        at com.genymobile.scrcpy.Server.main(Server.java:110)

Also downscale and retry in these cases.

2faf9715be Add server option raw_video_stream
For convenience, this new option forces the 3 following options:
 - send_device_meta=false
 - send_frame_meta=false
 - send_dummy_byte=false

This allows to send a raw H.264 stream on the video socket.

Concretely:

    adb push scrcpy-server /data/local/tmp/scrcpy-server.jar
    adb forward tcp:1234 localabstract:scrcpy
    adb shell CLASSPATH=/data/local/tmp/scrcpy-server.jar \
        app_process / com.genymobile.scrcpy.Server 1.21 \
        raw_video_stream=true tunnel_forward=true control=false

As soon as a client connects via TCP to localhost:1234, it will receive
the raw H.264 stream.

2eb6fe7d81 Downsize on error only before the first frame
The purpose of automatic downscaling on error is to make mirroring work
by just starting scrcpy without an explicit -m value, even if the
encoder could not encode at the screen definition.

It is only useful when we detect an encoding failure before the first
frame. Downsizing later could be surprising, so disable it.

e2b3968c66 Always synchronize clipboard on explicit COPY/CUT
If --no-clipboard-autosync is enabled, the automatic clipboard
synchronization performed whenever the device clipboard changes is
disabled.

But on explicit COPY and CUT scrcpy shortcuts (MOD+c and MOD+x), the
clipboard should still be synchronized, so that it remains possible to
copy-paste from the device to the computer.

This is consistent with the behavior of MOD+v, which pastes the computer
clipboard to the device.

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).
