avio_size() reports the filesize which returns 0 for /dev/null.
avio_tell() reports the current position.

Also handle errors from avio_tell().

Fixes CID700635, CID700636 and CID732274.

It is not used anymore and is a kludge.

The code shared is not actually shared with anything else.

ff_raw_read_header is used only for this demuxer for video.

The function is used elsewhere and does not belong with the LZO code.

Avoids memleaks with audio when extended_data is nontrivial and the user
doesn't reset the frame.
Shouldn't have any effect for video for now, but might be useful in the

Also fixes 3 compiler warnings about using uninitialized variables.

Since the requirement for output padding has been lifted, we can
use av_memcpy_backptr() here as well.

The function can return either a parsing error or a memory management
error.

Properly forward mp_decode_layer3 errors, mp_decode_layer1 and
mp_decode_layer2 do not return errors.

This adds support for building on Plan 9 x86-32.  The compat/plan9
directory contains these items:

- replacements for the 'head' and 'printf' shell commands
- wrapper for main() to disable FPU exceptions

Larger required changes to the system are described in the
documentation.

The absence of this function will only give a less informative
string back from our fallback implementation of getnameinfo().
