ffmpeg | branch: master | Henrik Gramner <henrik at gramner.com> | Sat Sep 26 22:27:36 2015 +0200| [2c3dbff1d89bbf8300c121c06524c014cb6e0915] | committer: Anton Khirnov

avutil/avstring: Inline some tiny functions

They're short enough that inlining them actually reduces code size due to
all the overhead associated with making a function call.
