Prior to this commit, most .c files in modules/audio_coding/codecs/ilbc don't include their corresponding headers, nor do they order #includes as per the Google Style Guide [1]. The former is especially harmful, since in C it can silently allow the function signature to diverge from its prototype, thus causing disaster at runtime. This CL fixes both issues. In effect, this allows the common_audio and modules/audio_coding:ilbc targets to be compiled with Clang's -Wmissing-prototypes, though this CL does not add that change.
