Expose an option to automatically configure and reconnect the device
over TCP/IP, to simplify wireless connection without using adb
explicitly.
There are two variants:
- If a destination address is provided, then scrcpy connects to this
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.
PR #2827 <https://github.com/Genymobile/scrcpy/pull/2827>
This will allow to read the property "service.adb.tcp.port" to know if
the TCP/IP mode is enabled on the device, and which listening port is
used.

Depending on the platform and adb versions, the lines output by adb
could end with "\r\r\n". This util function helps to remove all trailing
'\r'.
PR #2827 <https://github.com/Genymobile/scrcpy/pull/2827>
"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".

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).
PR #2827 <https://github.com/Genymobile/scrcpy/pull/2827>
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.
PR #2827 <https://github.com/Genymobile/scrcpy/pull/2827>
If SOCK_CLOEXEC exists, then set the flag on socket creation.
Otherwise, use fcntl() (or SetHandleInformation() on Windows) to set the
flag afterwards.
This avoids the sockets to be inherited in child processes.

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.
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.

Pass the information that device clipboard has been set to the key
processor. This avoids the keyprocessor to "guess", and paves the way to
implement a proper acknowledgement mechanism.

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_.
Refs #2807 <https://github.com/Genymobile/scrcpy/pull/2807>
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.

Inconditionnally print the scrcpy version first, without using LOGI().
The log level is configured only after parsing the command line
parameters (it may be changed via -V), and command line parsing logs
should not appear before the scrcpy version.
The output of -h/--help was printed on stderr, although it is not an
error.
Printing on stdout allows to pipe the result directly:
scrcpy --help | less
Instead of (in bash):
scrcpy --help |& less
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.
The interruptible version of the function to check process success
(sc_process_check_success_intr()) did not accept a close parameter to
avoid a race condition. But as the result, the processes were not closed
at all.
Add a close parameter, and close the process separately to avoid the
race condition.
Interrupt any blocking call on process terminated, like on
server_stop().
This allows to interrupt any blocking accept() with correct
synchronization without additional complexity.
Define server callbacks, start the server asynchronously and listen to
connection events to initialize scrcpy properly.
It will help to simplify the server code, and allows to run the UI event
loop while the server is connecting. In particular, this will allow to
receive SIGINT/Ctrl+C events during connection to interrupt immediately.
Currently, server_stop() is called from the same thread as
server_connect_to(), so interruption may never happen.
This is a step to prepare executing the server from a dedicated thread.
