  1. Move xGA font data from lavc to lavu. 

    This needs to be accessible for libavfilter in the next commit.

  4. isom: fix redundant redeclaration of ff_mov_read_chan(). 

    Silence a GCC warning. A leftover of the disabled version is still
available in lavf/isom.c.

  5. nutenc: use 1/sample rate as timebase for audio instead of framesize/… 

    …sample rate

This way audio frames can be exactly stored even when they are not
aligned with timestamp 0

  6. nut: store and read the r_frame_rate 

    With this, when we use a finer timebase than neccessary to store
durations the demuxer still knows what the original timebase was.

  7. nutenc: choose for non audio streams a timebase with finer resolution. 

    While a 25 fps stream can in general store frame durations in 1/25
units, this is not true for the timestamps. For example a 25fps
and a 25000/1001 fps stream when they are stored together might have
a matching 0 timestamp point but when for example a chapter from
this is cut the new start is no longer aligned. The issue gets
MUCH worse when the streams are lower fps, like 1 or 2 fps.

This commit thus makes the muxer choose a multiple of the
framerate as timebase that is at least about 20 micro seconds precise
