Create an AudioRecorder to capture the audio source REMOTE_SUBMIX.
For now, the captured packets are just logged in the console.

When audio is enabled, open a new socket to send the audio stream from

Audio will be enabled by default (when supported). Add an option to
disable it.

Since scrcpy-server is not an Android application (it's a java
executable), it has no Context.
Some features will require a Context instance to get the package name
and the UID. Add a FakeContext for this purpose.

The Callbacks interface notifies new packets. But in addition, the
screen encoder will need to write headers on start.
We could add a function onStart(), but for simplicity, just remove the
interface, which brings no value, and call the streamer directly.

On any error, all previously opened sockets must be closed.
Handle these errors in a single catch-block. Currently, there are only 2
sockets, but this will simplify even more with more sockets.
Note: this commit is better displayed with --ignore-space-change (-b).
On close, the client closes the socket. This wakes up socket blocking
calls on the server-side, by throwing an exception. Since this exception
is expected, it was not logged.
However, other IOExceptions might occur, which must not be ignored. For
that purpose, log only IOException when they are not caused by an EPIPE
error.
The PTS received from MediaCodec are expressed relative to an arbitrary
clock origin. We consider the PTS of the first frame to be 0, and the
PTS of every other frame is relative to this first PTS (note that the
PTS is only used for recording, it is ignored for mirroring).
For simplicity, this relative PTS was computed on the server-side.
To prepare support for multiple stream (video and audio), send the
packet with its original PTS, and handle the PTS offset on the
client-side (by the recorder).
Since we can't know in advance which stream will produce the first
packet with the lowest PTS (a packet received later on one stream may
have a PTS lower than a packet received earlier on another stream),
computing the PTS on the server-side would require unnecessary waiting.
On mouse click events:
- the first button pressed must first generate ACTION_DOWN;
- all button pressed (including the first one) must generate
ACTION_BUTTON_PRESS;
- all button released (including the last one) must generate
ACTION_BUTTON_RELEASE;
- the last button released must in addition generate ACTION_UP.
Otherwise, Chrome does not work properly.

If the pointer is a mouse, the pointer is UP only when no buttons are
pressed (not when a button is released, because there might be other
buttons still pressed).

MediaCodec may fail spuriously, typically when stopping an encoding and
starting a new one immediately (for example on device rotation).
In that case, retry a few times, in many cases it should work.

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").
