Romain Vimont 6abff46c9f Add option to disable clipboard autosync
By default, scrcpy automatically synchronizes the computer clipboard to
the device clipboard before injecting Ctrl+v, and the device clipboard
to the computer clipboard whenever it changes.

This new option --no-clipboard-autosync disables this automatic
synchronization.

Romain Vimont 5d17bcf1bc Wait SET_CLIPBOARD ack before Ctrl+v via HID
To allow seamless copy-paste, on Ctrl+v, a SET_CLIPBOARD request is
performed before injecting Ctrl+v.

But when HID keyboard is enabled, the Ctrl+v injection is not sent on
the same channel as the clipboard request, so they are not serialized,
and may occur in any order. If Ctrl+v happens to be injected before the
new clipboard content is set, then the old content is pasted instead,
which is incorrect.

To minimize the probability of occurrence of the wrong order, a delay of
2 milliseconds was added before injecting Ctrl+v. Then 5ms. But even
with 5ms, the wrong behavior sometimes happens.

To handle it properly, add an acknowledgement mechanism, so that Ctrl+v
is injected over AOA only after the SET_CLIPBOARD request has been
performed and acknowledged by the server.

Romain Vimont 68eaee5bb0 Force adb forward if tunnel host/port is provided
Tunnel host and port are only meaningful in "adb forward" mode.

They indicate where the client must connect to communicate with the
server. In "adb reverse" mode, the client _listens_, it does not
_connect_.

RipleyTom 7bdbde7363 Add options to configure tunnel host and port
In "adb forward" mode, by default, scrcpy connects to localhost:PORT,
where PORT is the local port passed to "adb forward". This assumes that
the tunnel is established on the local host with a local adb server
(which is the common case).

For advanced usage, add --tunnel-host and --tunnel-port to force the
connection to a different destination.

Romain Vimont 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.

Romain Vimont 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).

Romain Vimont 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:
