Rename directories, move files (step 2 of 2) Finish renaming directories and moving files. Adjust all include statements to make the previous commit compile. The two commits are separate, because git is bad at tracking renames and content changes at the same time. Also take this as an opportunity to remove the separation between "common" and "mplayer" sources in the Makefile. ("common" used to be shared between mplayer and mencoder.)

Remove vo_fps global variable This is needed by the encode stuff for some reason, so we have to explicitly pass it. Functionality shouldn't change.

Replace all calls to GetTimer()/GetTimerMS() GetTimer() is generally replaced with mp_time_us(). Both calls return microseconds, but the latter uses int64_t, us defined to never wrap, and never returns 0 or negative values. GetTimerMS() has no direct replacement. Instead the other functions are used. For some code, switch to mp_time_sec(), which returns the time as double float value in seconds. The returned time is offset to program start time, so there is enough precision left to deliver microsecond resolution for at least 100 years. Unless it's casted to a float (or the CPU reduces precision), which is why we still use mp_time_us() out of paranoia in places where precision is clearly needed. Always switch to the correct time. The whole point of the new timer calls is that they don't wrap, and storing microseconds in unsigned int variables would negate this. In some cases, remove wrap-around handling for time values.

Take care of some libavutil deprecations, drop support for FFmpeg 1.0 PIX_FMT_* -> AV_PIX_FMT_* (except some pixdesc constants) enum PixelFormat -> enum AVPixelFormat Losen some version checks in certain newer pixel formats. av_pix_fmt_descriptors -> av_pix_fmt_desc_get This removes support for FFmpeg 1.0.x, which is even older than Libav 9.x. Support for it probably was already broken, and its libswresample was rejected by our build system anyway because it's broken. Mostly untested; it does compile with Libav 9.9.
