> CreateProcess fails with ERROR_NO_SYSTEM_RESOURCES on Windows 7. It

Romain Vimont 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.

Expose an option to automatically configure and reconnect the device

There are two variants:

   address before starting. The device must listen on the given TCP port
   (default is 5555).
 - If no destination address is provided, then scrcpy attempts to find
   the IP address of the current device (typically connected over USB),
   enables TCP/IP mode, then connects to this address before starting.

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.

connection to a different destination.

To be able to communicate with a child process via stdin, stdout and

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:
