c070723bc8 Add sc_vector
Adapt vlc_vector [1], that I initially wrote while implementing the VLC
playlist [2].

Change the implementation to use "statement expressions" [3], which are
forbidden in VLC because "non-standard", but:
 - they are supported by gcc and clang;
 - they are already used in the scrcpy codebase;
 - they avoid implementation hacks (VLC_VECTOR_FAILFLAG_);
 - they allow a better API (sc_vector_index_of() may return the result
   without an output parameter).

73a5311ac6 Forbid HID input without OTG on Windows
On Windows, if the adb daemon is running, opening the USB device will
necessarily fail, so HID input is not possible.

3bb24b3926 Make intr optional for adb commands
All adb commands are executed with an "interruptor", so that they can be
interrupted on Ctrl+C.

Make this interruptor optional, so that we could call "adb kill-server"
in OTG mode. This command always returns almost immediately anyway.

Ideally, we should make all blocking calls interruptible (including
libusb calls, by using the asynchronous API), but it's a lot of work,
and in practice it works well enough.

85edba20e7 Enforce deadline reached on timeout
The value of sc_tick_now() has microsecond precision, but
sc_cond_timedwait() has only millisecond precision.

To guarantee that sc_tick_now() >= deadline when sc_cond_timedwait()
returns due to timeout, round up to the next millisecond.

This avoids to call a non-blocking sc_cond_timedwait() in a loop for no
reason until a target deadline during up to 1 millisecond.

582161607e Add option to select USB or TCP/IP devices
If several devices are connected (as listed by `adb devices`), it was
necessary to provide the explicit serial via -s/--serial.

If only one device is connected via USB (respectively, via TCP/IP), it
might be convenient to select it automatically. For this purpose, two
new options are introduced:
 - -d/--select-usb: select the single device connected over USB
 - -e/--select-tcpip: select the single device connected over TCP/IP

0a619dc9ef Allow selecting a device from IP without port
Since the previous commit, if a serial is given via -s/--serial (either
a real USB serial or an IP:port), a device is selected if its serial
matches exactly.

In addition, if the user pass an IP without a port, then select any
device with this IP, regardless of the port (so that "192.168.1.1"
matches any "192.168.1.1:port"). This is also the default behavior of

137d2c9791 Remove confusing sc_str_truncate()
This util function was error-prone:
 - it accepted a buffer as parameter (not necessarily a NUL-terminated
   string) and its length (including the NUL char, if any);
 - it wrote '\0' over the last character of the buffer, so the last
   character was lost if the buffer was not a NUL-terminated string, and
   even worse, it caused undefined behavior if the length was empty;
 - it returned the length of the resulting NUL-terminated string,
   which was inconsistent with the input buffer length.

In addition, it was not necessarily optimal:
 - it wrote '\0' twice;
 - it required to know the buffer length, that is the input string
   length + 1, in advance.

Remove this function, and let the client use strcspn() manually.

nonetheless.

5b3ae2cb2f Store actual serial in sc_server
Before starting the server, the actual device serial (possibly its
ip:port if it's over TCP/IP) must be known.

A serial might be requested via -s/--serial (stored in the
sc_server_params), but the actual serial may change afterwards:
 - if none is provided, then it is retrieved with "adb get-serialno";
 - if --tcpip is requested, then the final serial will be the target
   ip:port.

The requested serial was overwritten by the actual serial in the
sc_server_params struct, which was a bit hacky.

Instead, store a separate serial field in sc_server (and rename the one
from sc_server_params to "req_serial" to avoid confusion).

c996a6d462 Fix socket close race condition
The server needs to interrupt the sockets on stop, but it must not close
them while other threads may attempt to read from or write to them.

In particular, the video_socket is read by the stream thread, and the
control_socket is written by the controller and read by receiver.

Therefore, close the socket only on sc_server_destroy(), which is called
after all other threads are joined.

Reported by TSAN on close:

In relative mouse mode, the mouse pointer must be "captured" from the
computer.

Toggle (disable/enable) relative mouse mode using any of the hardcoded
capture keys:
 - left-Alt
 - left-Super
 - right-Super

These capture keys do not conflict with shortcuts, since a shortcut is
always a combination of the MOD key and some other key, while the
capture key triggers an action only if it is pressed and released alone.

The relative mouse mode is also automatically enabled on any click in
the window, and automatically disabled on focus lost (it is possible to
lose focus even without the mouse).

6102a0b5bb Move input_manager into screen
The input_manager is strongly tied to the screen, it could not work
independently of the specific screen implementation.

To implement a user-friendly HID mouse behavior, some SDL events
will need to be handled both by the screen and by the input manager. For
example, a click must typically be handled by the input_manager so that
it is forwarded to the device, but in HID mouse mode, the first click
should be handled by the screen to capture the mouse (enable relative
mouse mode).

Make the input_manager a descendant of the screen, so that the screen
decides what to do on SDL events.

Concretely, replace this structure hierarchy:

     +- struct scrcpy
        +- struct input_manager
        +- struct screen

by this one:

     +- struct scrcpy
        +- struct screen

d049671908 Fix adb server hang
Since commit 0426708544, the server is run
in a dedicated thread. For SDL, many signals, including SIGINT and
SIGTERM, are masked for new threads. As a result, if the adb server is
not already running, adb commands invoked by scrcpy will start an adb
server that ignores those signals and cannot be terminated at system
shutdown.

The sockets were never interrupted or closed by the client since recent
changes to run the server from a dedicated thread (see commit
0426708544).

As a side effect, the server could never terminate properly (it was

after the WATCHDOG_DELAY.

property, then close them.

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.

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.

5b3856c3b6 Explicitly indicate when device clipboard is set
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.

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.

6da6d905c2 Print scrcpy header first
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.

b25404ee4b Print help to stdout
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
