0b61ddb576 avformat/matroskaenc: Don't waste bytes writing level 1 elements
Up until now, the length field of most level 1 elements has been written
using eight bytes, although it is known in advance how much space the
content of said elements will take up so that it would be possible to
determine the minimal amount of bytes for the length field. This
commit changes this.

4e6df068b5 avformat/matroskaenc: Don't waste bytes in EBML Header
Up until now the EBML Header length field has been written with eight
bytes, although the EBML Header is always so small that only one byte
is needed for it. This patch saves seven bytes for every Matroska/Webm
file.

90826031a2 avformat/matroskaenc: write a DisplayUnit element when aspect ratio is unknown
We don't currently support values 1 (centimeters), 2 (inches) or 3 (DAR),
only the default value 0 (pixels) which doesn't need to be written.

The fate refs are updated as unknown SAR is now signaled in the output
files with the addition of the new element.

81eec081af matroskaenc: base DefaultDuration on the framerate, not the codec timebase
This results in DefaultDuration not being written when the framerate is
not known, but as this field is purely informative, this should not
break any sane demuxers.

f812eeda17 matroskaenc: Fix writing TRACKDEFAULTFLAG
The element was only being written when the value == 1.  But the default
value of this element is 1, so this has no useful effect.  This element
needs to be written when the value == 0.
