Add FPS counter Remove frame counter from scrcpy.c and add a new FPS counter, logging as INFO the measured frame rate every second (on new frame).

#ifndef FPSCOUNTER_H
#define FPSCOUNTER_H
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_Atomic by stdatomic from C11 There is no reason to use SDL atomics.

#include <stdatomic.h>
Replace SDL types by C99 standard types Scrcpy is a C11 project. Use the C99 standard types instead of the SDL-specific types: SDL_bool -> bool SintXX -> intXX_t UintXX -> uintXX_t

Improve framerate counting The FPS counter was called only on new frames, so it could not print values regularly, especially when there are very few FPS (when the device surface does not change). To the extreme, it was never able to display 0 fps. Add a separate thread to print framerate every second.

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.)
