Mark bktr_init function as av_cold.
Tested to work by Michael Kostylev on the NetBSD FATE box.

This make NetBSD compile out of the box at the cost of a hack, but a
locally contained one that is preferable to the one used in the wild.
Currently the NetBSD FATE box adds -D_NETBSD_SOURCE to CPPFLAGS to work
around broken system headers. Since it is unlikely for NetBSD to fix their
headers, it is better to use a standard flag instead of a system-specific one.

As a sideeffect, this allows getting rid of a local _NETBSD_SOURCE definition.

Previously, the area of a lost slice would be left at the slice number of the previous
frame which could occasionally match the number of the next slice and thus a non existing
slice could have been used for prediction leading to additional decoding errors in otherwise
undamaged slices.

This fixes some old ogm files that had the 3rd vorbis header after a data
packet in another stream. This is invalid in ogg, but this change shouldn't
affect the behaviour of any valid file.

If size == 1 and buf[0] == 0 and buf[1] == 0 (the first byte after the
buffer), it would set size = -1 and crash in the later memcpy.

of packets, and sets the correct file offset of the associated page.

w53_32_c() and w97_32_c() are defined as stubs when snow encoder is
disabled.  In this case, those functions are not referenced at all
and do thus not need to be defined.
