b7e3ae19b8 avdevice/lavfi: Simplify setting sample_fmts 
The length of this list is a compile-time constant, so there is
no need to calculate it again at runtime.
(This also avoids an implicit requirement of -1 == AV_SAMPLE_FMT_NONE.)

84f037edc2 avdevice/lavfi: Don't unnecessarily write '\0' to AVBPrint 
An AVBPrint's internal string is always already zero-terminated;
writing another '\0' is unnecessary as long as one treats
the string only as a C-string.

5c2c35da12 avdevice/lavfi: Remove redundant av_packet_unref() 
Since bae8844e35, the AVPacket that is
intended to be used to return the demuxed packet is automatically
unreferenced when the demuxer returns an error. This makes an
av_packet_unref() in the lavfi demuxer redundant.

901251d59b avdevice/lavfi: Don't set pkt->size to the value it already has 
av_new_packet() already sets the size. And if the packet is not
allocated by av_new_packet() (which seems to be impossible atm), both
pkt->size as well as size are 0, so setting it again is unnecessary in
this scenario, too.

9514472904 avutil & avdevice: remove av_bprint_fd_contents() 
MSVC does not allow passing file pointers between libs
This API can thus not work with MSVC and as it was very recently added
and its it was in no release its removial should not cause any problems

A better API will be implemented, but its not finished yet, this revert is
to avoid potentially blocking the release
