4abc411b97 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

e3fb5bc147 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.

This way audio frames can be exactly stored even when they are not

f4d9148fe2 qt-faststart: speedup 
qt-faststart is terribly slow when the input file and the output file
are on a slow disk like a SD card. By increasing the copy_buffer from
1K to 32M I decreased the processing time on a sample file from
1600 seconds to 4 seconds. The timing difference is during 'copying
rest of file'.
