b5d41ad4f6 Fix useless garbage initialization
The variable `p` was initialized with a garbage value (a `const char **`
casted to `char *`). Fortunately, it was never read.

3c3c07db05 Initialize server->serial in all cases
Running scrcpy --tcpip on a device already connected via TCP/IP did not
initialize server->serial.

As a consequence, in debug mode, an assertion failed:

    scrcpy: ../app/src/server.c:770: run_server: Assertion
    `server->serial' failed.

In release mode, scrcpy failed with this error:

    adb: -s requires an argument

439a1fd4ed Rename 'uid' to 'scid'
A random identifier is generated to differentiate multiple running
scrcpy instances. Rename it from 'uid' to 'scid' (scrcpy id) not to
confuse it with Linux UID.

4315be1648 Use random name for device socket
For the initial connection between the device and the computer, an adb
tunnel is established (with "adb reverse" or "adb forward").

The device-side of the tunnel is a local socket having the hard-coded
name "scrcpy". This may cause issues when several scrcpy instances are
started in a few seconds for the same device, since they will try to
bind the same name.

To avoid conflicts, make the client generate a random UID, and append
this UID to the local socket name ("scrcpy_01234567").

bd1deffa70 Use current adb port (if any) for --tcpip
If the current adb port is not 5555 (typically 0 because it is not in
TCP/IP mode), --tcpip automatically executes (among other commands):

    adb tcpip 5555

In case adb was already listening on another port, this command forced
to listen on 5555, and the connection should still succeed.

But this reconfiguration might be inconvenient for the user. If adb is
already in TCP/IP mode, use the current enabled port without
reconfiguration.

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

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.

ddb9396743 Interrupt and close sockets on server stop
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
waiting on socket blocking calls), so it was always killed by the client
after the WATCHDOG_DELAY.

Interrupt the sockets on stop to give the servera chance to terminate
property, then close them.

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.
