#include "fps_counter.h"
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).

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.)
