Prevent an use after free in the error message.

Bug-Id: CID 1274040
CC: libav-stable@libav.org

The valid returned values are always at most 11bit.
Remove the previous check that assumed larger values plausible and
use a signed integer to check get_vlc2 return values.

CC: libav-stable@libav.org

Makes the code a little simpler.

This prevents a memcpy if segmentation.update_map == false.

Fixes out of array access
Fixes: ffmpeg_opus_crash1.ogg

This solution is likely not optimal in terms of error concealment but
its simple and fixes the out of array access.

This is safer than to assume that all error pathes cleared them and
nothing will use uncleared pointers.

When all the codepaths using manually set .arch/.fpu code is
behind runtime detection, the elf attributes should be suppressed.

This allows tools to know that the final built binary doesn't
strictly require these extensions.
