avutil/stereo3d: add a Stereo3D type to signal that the packing is unspecified
...
Given that a video stream/frame may have only one view or both views coded with
the packing information being unavailable, this commit adds a new type value
AV_STEREO3D_UNSPEC for this purpose.
The most common case for this is container level signaling of Stereo3D video
where the specifics are defined at the bitstream level.

lavu/stereo3d: change the horizontal FOV field to a rational
...
This avoids hardcoding any implementation-specific limitiations as
part of the API, and allows for future expandability.
This also allows API users to more conveniently convert the
values into floats without hardcoding specific conversion constants.
The API was committed a few days ago, so changing this field now
is within the realms of acceptable.

Remove unnecessary libavutil/(avutil|common|internal).h inclusions
...
Some of these were made possible by moving several common macros to
libavutil/macros.h.
While just at it, also improve the other headers a bit.
