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.

Some formats like FLV can dynamically add streams during packet reading.
FFprobe does check for this and reallocates the global stream info, but does
not reallocate InputFrame's streams and decoders when this happens, which,
as a result, could have caused flushing to occur on an out of bounds stream
index, since the flush loop iterates over fmt_ctx's nb_streams, and not
ifile's, despite using ifile's streams.
This fixes an out of bounds read and segfult.

av_err2str which is a wrapper for av_strerror already calls
strerror_r if available and if not has a fallback for the other
error codes that would be handled by that, so manually calling
strerror again if it fails is not necessary.

av_display_rotation_get will return NAN when the display matrix is invalid,
which would end up printing NAN as an integer in the rotation field. This
is poor for multiple reasons:
* Users of ffprobe have no way of discerning "valid but ugly rotation from
display matrix" from "invalid display matrix".
* It can have unintended consequences on some platforms, such as Linux x86_64,
where NAN is equal to INT64_MIN, which, for example, when printed as JSON,
which uses floating point for all numbers, can end up as invalid JSON or wit
a number that cannot be reserialized as an integer at all.
Since NAN is av_display_rotation_get's error case, just print 0 (no rotation)
when that happens.

c11fb46731 led to a regression whereby the return code for missing
input or input probe is overridden by writer close return code and
hence not conveyed in the exit code.
These packets need not be writable (and are not modified by us),
so it is best to access them via const uint8_t*.

It tries to process any unhandled options as AVOptions. Handle this
directly in cmdutils.c, without resorting to a confusing fake option
definition (which is currently visible to the users in -help output).
