avformat/asfdec_o: Don't segfault with lots of attached pics
The ASF file format has a limit of 127 streams and the "asf_o" demuxer
(the ASF demuxer from Libav) has an array of pointers for a structure
called ASFStream that is allocated on demand for every stream. Attached
pictures are not streams in the sense of the ASF specification, yet the
demuxer created an ASFStream for them; and in one codepath it also
forgot to check whether the array of ASFStreams is already full. The
result is a write beyond the end of the array and a segfault lateron.
Fixing this is easy: Don't create ASFStreams for attached picture
streams.
(Other results of the current state of affairs are unnecessary allocations
(of ASFStreams structures), the misparsing of valid files (there might not
be enough ASFStreams left for the valid streams if attached pictures take
up too many); furthermore, the ASFStreams created for attached pictures all
have the stream number 0, an invalid stream number (the valid range is
1-127). This means that invalid data (packets for a stream with stream
number 0) won't get rejected lateron.)

aviobuf: Increase the default SHORT_SEEK_THRESHOLD to 32 KB
The previous threshold, 4 KB, maybe was reasonable when it was set
(in 2010), but in today's settings and with typical network speeds
and data sizes, it's pretty small. 32 KB probably is a more reasonable
default now, regardless of input.
This changes the test references for two seek tests.
When using the normal seek function, which boils down to the lseek(2)
function, a seek to an out of bounds position doesn't return an error,
but that condition is only reported when doing the subsequent read
(which returns EOF). When doing more seeks by fast forwarding, the
fact that the seeked to destination is out of bounds is noticed and
reported sooner in these cases.

avcodec/gdv: Remove dead check
At the end of its decode function, the decoder sets *got_frame to 1 and
then checks whether ret is < 0; if so, it is returned, otherwise
avpkt->size is. But it is impossible for ret to be < 0 here and if it
were, it would be nonsense to set *got_frame to 1 before this. Therefore
just return avpkt->size unconditionally.
