Currently we have -of and -print_format, which is a bit confusing. Add
-output_format as an alias of -of to match the short name.

Fix rendering of int values within a side data element, which was
broken since commit d2d3a83a, where the side data element was
correctly marked as a variable fields element. Logic to render a
string variable was implemented already, but it was not implemented
for the int fields path, which was enabled by that commit.

Also, code and schema is changed in order to account for multiple
variable-fields elements - such as side data, contained within the
same parent. Previously it was assumed that a single variable-fields
element was contained within the parent, which was the case for tags,
but is not the case for side-data.

Previously data was rendered as:
<side_data_list>
    <side_data side_data_type="CPB properties" max_bitrate="0" min_bitrate="0" avg_bitrate="0" buffer_size="327680" vbv_delay="-1"/>
</side_data_list>

Now as:
<side_data_list>
   <side_data type="CPB properties">
       <side_datum key="side_data_type" value="CPB properties"/>
       <side_datum key="max_bitrate" value="0"/>
       <side_datum key="min_bitrate" value="0"/>
       <side_datum key="avg_bitrate" value="0"/>
       <side_datum key="buffer_size" value="49152"/>
       <side_datum key="vbv_delay" value="-1"/>
   </side_data>
</side_data_list>

Variable-fields elements are rendered as a containing element wrapping
generic key/values elements, enabling use of strict XML schema.

It is badly named (should have been -top_field_first, or at least -tff),
underdocumented and underspecified, and (most importantly) entirely
redundant with the setfield filter.

Keyframes are marked automagically

I've been sitting on this for 3 1/2 years now(!), and I finally got
around to fixing the loose ends and convincing myself that it was
correct. It follows the same basic structure as yadif_cuda, including
leaving out the edge handling, to avoid expensive branching.
