83ace84280 Restore the .jar extension on the device side
Commit 3da95b52bd renamed
'scrcpy-server.jar' to 'scrcpy-server' to avoid issues on the client
side.

However, removing the extension may cause issues with app_process, so
restore the extension only on the device side.

53b6ee2cf4 Add generic intrusive FIFO queue
We need several FIFO queues (a queue of packets, a queue of messages,
etc.).

Some of them are implemented using cbuf, a generic circular buffer. But
for recording, we need to store the packets in an unbounded queue until
they are written, so the queue was implemented manually.

Create a generic implementation (using macros) to avoid reimplementing
it every time.

35d9185f6c Record asynchronously

63af7fbafe Reduce latency by 1 frame
To packetize the H.264 raw stream, av_parser_parse2() (called by
av_read_frame()) knows that it has received a full frame only after it
has received some data for the next frame. As a consequence, the client
always waited until the next frame before sending the current frame to
the decoder!

On the device side, we know packets boundaries. To reduce latency,
make the device always transmit the "frame meta" to packetize the stream
manually (it was already implemented to send PTS, but only enabled on
recording).

On the client side, replace av_read_frame() by manual packetizing and
parsing.

 - Ctrl+o to turn the device screen off while mirroring
 - Ctrl+Shift+o to turn it back on

On power on (either via the POWER key or BACK while screen is off), both
the device screen and the mirror are turned on.

28980bbc90 Rename "event" to "message"
After the recent refactorings, a "control event" is not necessarily an
"event" (it may be a "command"). Similarly, the unique "device event"
used to send the device clipboard content is more a "reponse" to the
request from the client than an "event".

Rename both to "message", and rename the message types to better
describe their intent.

c13a24389c Implement computer-to-device clipboard copy
It was already possible to _paste_ (with Ctrl+v) the content of the
computer clipboard on the device. Technically, it injects a sequence of
events to generate the text.

Add a new feature (Ctrl+Shift+v) to copy to the device clipboard
instead, without injecting the content. Contrary to events injection,
this preserves the UTF-8 content exactly, so the text is not broken by
special characters.

e6e011baaf Add stream layer
The decoder initially read from the socket, decoded the video and sent
the decoded frames to the screen:

              +---------+      +----------+
  socket ---> | decoder | ---> |  screen  |
              +---------+      +----------+

The design was simple, but the decoder had several responsabilities.

Then we added the recording feature, so we added a recorder, which
reused the packets received from the socket managed by the decoder:

                                    +----------+
                               ---> |  screen  |
              +---------+     /     +----------+
  socket ---> | decoder | ----
              +---------+     \     +----------+
                               ---> | recorder |
                                    +----------+

This lack of separation of concerns now have concrete implications: we
could not (properly) disable the decoder/display to only record the
video.

Therefore, split the decoder to extract the stream:

                                    +----------+      +----------+
                               ---> | decoder  | ---> |  screen  |
              +---------+     /     +----------+      +----------+
  socket ---> | stream  | ----
              +---------+     \     +----------+
                               ---> | recorder |
                                    +----------+

This will allow to record the stream without decoding the video.

fefb9816a9 Handle mouse events outside device screen
Mouse events position were unsigned (so negative values could not be

To avoid issues with negative values, mouse events outside the device
screen were ignored (commit a7fe9ad779).

But as a consequence, drag&drop were "broken" if the "drop" occurred
outside the device screen.

Instead, use signed 32-bits to store the position, and forward events
outside the device screen.

1038bad385 Make it work over tcpip
"adb reverse" currently does not work over tcpip (i.e. on a device
connected by "adb connect"):
<https://issuetracker.google.com/issues/37066218>

To work around the problem, if the call to "adb reverse" fails, then
fallback to "adb forward", and reverse the client/server roles.

Keep the "adb reverse" mode as the default because it does not involve
connection retries: when using "adb forward", the client must try to
connect successively until the server listens.

Due to the tunnel, every connect() will succeed, so the client must
attempt to read() to detect a connection failure. For this purpose, when
using the "adb forward" mode, the server initially writes a dummy byte,
read by the client.

The text input control_event was initially designed for mapping
SDL_TextInputEvent, limited to 32 characters.

For simplicity, the copy/paste feature was implemented using the same
control_event: it just sends the text to paste.

However, the pasted text might have a length breaking some assumptions:
 - on the client, the event max-size was smaller than the text
   max-length,
 - on the server, the raw buffer storing the events was smaller than the
   max event size.

Fix these inconsistencies, and encode the length on 2 bytes, to accept
more than 256 characters.

db396f2138 Fix scroll wheel mouse position
SDL_MouseWheelEvent does not provide the mouse location, so we used
SDL_GetMouseState() to retrieve it.

Unfortunately, SDL_GetMouseState() returns a position expressed in the

expressed in the renderer coordinate system. As a consequence, the
scroll was not applied at the right position on the device.

Therefore, convert the coordinate system.

9b056f5091 Replace SDL_net by custom implementation
SDL_net is not very suitable for scrcpy.

For example, SDLNet_TCP_Accept() is non-blocking, so we have to wrap it
by calling many SDL_Net-specific functions to make it blocking.

But above all, SDLNet_TCP_Open() is a server socket only when no IP is
provided; otherwise, it's a client socket. Therefore, it is not possible
to create a server socket bound to localhost, so it accepts connections
from anywhere.

This is a problem for scrcpy, because on start, the application listens
for nearly 1 second until it accepts the first connection, supposedly
from the device. If someone on the local network manages to connect to
the server socket first, then they can stream arbitrary H.264 video.
This may be troublesome, for example during a public presentation ;-)

Provide our own simplified API (net.h) instead, implemented for the
different platforms.

eb09fefd43 Timeout the server socket connection

90a46b4c45 Improve startup time
On startup, the client has to:
 1. listen on a port
 2. push and start the server to the device
 3. wait for the server to connect (accept)
 4. read device name and size
 5. initialize SDL
 6. initialize the window and renderer
 7. show the window

From the execution of the app_process command to start the server on the
device, to the execution of the java main method, it takes ~800ms. As a
consequence, step 3 also takes ~800ms on the client.

Once complete, the client initializes SDL, which takes ~500ms.

These two expensive actions are executed sequentially:

                     HOST              DEVICE
listen on port        |                  |
push/start the server |----------------->|| app_process loads the jar
accept the connection .   ^              ||
                      .   |              ||
                      .   | WASTE        ||
                      .   |  OF          ||
                      .   | TIME         ||
                      .   |              ||
                      .   |              ||
                      .   v              X execution of our java main
connection accepted   |<-----------------| connect to the host
init SDL             ||                  |
                     || ,----------------| send frames
                     || |,---------------|
                     || ||,--------------|
                     || |||,-------------|
                     || ||||,------------|
init window/renderer  | |||||,-----------|
display frames        |<++++++-----------|
(many frames skipped)

The rationale for step 3 occuring before step 5 is that initializing
SDL replaces the SIGTERM handler to receive the event in the event loop,
so pressing Ctrl+C during step 5 would not work (since it blocks the
event loop).

But this is not so important; let's parallelize the SDL initialization
with the app_process execution (we'll just add a timeout to the
connection):

                     HOST              DEVICE
listen on port        |                  |
push/start the server |----------------->||app_process loads the jar
init SDL             ||                  ||
                     ||                  ||
                     ||                  ||
                     ||                  ||
                     ||                  ||
                     ||                  ||
accept the connection .                  ||
                      .                  X execution of our java main
connection accepted   |<-----------------| connect to the host
init window/renderer  |                  |
display frames        |<-----------------| send frames
                      |<-----------------|

In addition, show the window only once the first frame is available to
avoid flickering (opening a black window for 100~200ms).

Note: the window and renderer are initialized after the connection is
accepted because they use the device information received from the
device.
