3bf6fd2894 Workaround "adb connect" error detection 
"adb connect" always returns successfully (with exit code 0), even in
case of failure.

As a workaround, capture its output and check if it starts with
"connected".

e6e6f865a0 Add adb flag to disable execution error logs 
In addition to disable stdout and stderr of the child process, add a
flag to disable the error log printed by scrcpy if the command failed.

This will we useful for commands which are expected to fail in some
cases (like "adb disconnect" if the device is not connected).

Let the caller decide if stdout and stderr must be inherited on process
creation, i.e. if stdout and stderr of the child process should be
printed in the scrcpy console.

This allows to get output and errors for specific adb commands depending
on the context.

04e5537f8c Pass server parameters as key=value pairs 
The options values to configure the server were identified by their
command-line argument index. Now that there are a lot of arguments, many

Identify the arguments by a key string instead, and make them optional.

This will also simplify running the server manually for debugging.

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.

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.

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_.

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.

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.

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:
