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.

Fixes <https://github.com/Genymobile/scrcpy/issues/5>.

2b3ed5bcdb Store serial in server instance
The serial is needed for many server actions, but this is an
implementation detail, so the caller should not have to provide it on
every call.

Instead, store the serial in the server instance on server_start().

This paves the way to implement the "adb forward" fallback properly.

f9a63ec272 Reverse horizontal scrolling behavior
The SDL mouse wheel event seems inconsistent between horizontal and
vertical scrolling.

> Movements to the left generate negative x values and to the right
> generate positive x values. Movements down (scroll backward) generate
> negative y values and up (scroll forward) generate positive y values.

<https://wiki.libsdl.org/SDL_MouseWheelEvent#Remarks>

Reverse the horizontal.

Also remove "zip", since it's only used for building a portable version
(which is not documented in README).

dac7196bd6 Support screens with dimensions not divisible by 8
The codec only supports dimensions which are multiple of 8.

Thus, when --max-size is specified, the value is always rounded down to
the nearest multiple of 8.

However, it was wrongly assumed that the physical size is always a
multiple of 8. To support such devices, also round down the physical
screen dimensions.

9396ea6d42 Fix text input event segfault
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.

Fixes <https://github.com/Genymobile/scrcpy/issues/10>.

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
window coordinate system while the position filled in SDL events are
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.

c78ad6377c Terminate the server on stop
On user request to quit, two kinds of blocking calls must be interrupted
on the server:
 1. the reads from and writes to the socket;
 2. the call to MediaCodec.dequeueOutputBuffer().

The former case was handled by calling shutdown() on the socket from the
client, but the latter was not managed.

There is no easy way to wake this call properly, so just terminate the
process from the client (i.e. send SIGTERM on Linux) instead.
