Components and pieces are side data specific fields and there's a variable
amount of them.
They also need to be identified in some form, so print a type too.

This option flag only carries nontrivial information for options that
call a function, in all other cases its presence can be inferred from
the option type (bool options do not have arguments, all other types do)
and is thus nothing but useless clutter.
Change the option parsing code to infer its value when it can, and drop
the flag from options where it's not needed.
Fix rendering of int values within a side data element, which was
broken since commit d2d3a83ad9, 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.
Fix trac issue:

Also, avoid spurious end-of-line after side data entries, and improve
rendering of compact output, by adding an indication of the side data
type for each entry.

These defines are also used in other contexts than just AVCodecContext
ones, e.g. in libavformat. Furthermore, given that these defines are
public, the AV-prefix is the right one, so deprecate (and not just move)
the FF-macros.

This is a bit cleaner as int need not be the underlying type
of an enum if a smaller type can hold all its values.
Also declare the children_ids array as const as it never changes.

These fields are ad-hoc and will be deprecated. Use the recently-added
AV_CODEC_FLAG_COPY_OPAQUE to pass arbitrary user data from packets to
frames.
Changes the result of the flcl1905 test, which uses ffprobe to decode
wmav2 with multiple frames per packet. Such packets are handled
internally by calling the decoder's decode callback multiple times,
offsetting the internal packet's data pointer and decreasing its size
after each call. The output pkt_size value before this commit is then
the remaining internal packet size at the time of each internal decode
call.
After this commit, output pkt_size is simply the size of the full packet
submitted by the caller to the decoder. This is more correct, since
internal packets are never seen by the caller and should have no
observable outside effects.
Their usefulness is questionable, very few decoders set them, and their type
should have been int64_t. A replacement field can be added later if a valid use
case is found.
