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.

Implement keyboard/mouse control To control the device from the computer: - retrieve mouse and keyboard SDL events; - convert them to Android events; - serialize them; - send them on the same socket used by the video stream (but in the opposite direction); - deserialize the events on the Android side; - inject them using the InputManager.

Define feature test macros in common.h This enables necessary functions once for all. As a consequence, define common.h before any other header.

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.

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.

Update code style Limit source code to 80 chars, and declare functions return type and modifiers on a separate line. This allows to avoid very long lines, and all function names are aligned. (We do this on VLC, and I like it.)
