Fix Ticket #1617, revealing a regression I introduced in 8f3eebd.
We need to make sure no stream is added in between Ogg context save and
restore operations (because it would likely lead to a mismatch between
ogg->nstreams and AVFormatContext->nb_streams after the restore op).
This is the reason the ogg->state check is added in ogg_new_stream().
Before this patch, checking for ogg->headers was preventing this:
ogg->headers is always set before any ogg save/restore (though, it was
also preventing from creating the stream when necessary).
Not all applications (e.g. MPlayer) set block_align, and
when using a different demuxer it might not even be
easily available.
So fall back to selecting mode based on bit rate as before
if block_align has not useful value.
It can't be worse than failing to decode completely.

When building Thumb2 code, the end of a function, where the PIC
offsets are placed, need not be aligned. Although the values
are only accessed with instructions allowing unaligned addresses,
keeping them aligned is preferable.

v5.0 of the TI ARM compiler changes the version string.
This updates the detection to check for both the old and
the new strings.

This occurs with fuzzed mpeg-ts files. set_codec_from_probe_data() is
called with a zeroed AVProbeData since no packet made through for
specific stream.
