Romain Vimont 7b29f5fd2d Do not pass default values to the server
By default, only pass the version and the bit rate (the default bitrate
is a client compilation option).

Romain Vimont 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
of them being booleans, it became unreadable and error-prone.

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

This will also simplify running the server manually for debugging.

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.

This allows to execute all adb commands with the specific -s parameter,

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:
