This means that avformat_find_stream_info() now works properly with
multiple threads, so there's no need to force thread count to 1.

Adds a new member to MpegEncContext to hold the number of used slice
contexts. Fixes segfaults with '-threads 17 -thread_type slice' and
fate-vsynth{1,2}-mpeg{2,4}thread{,_ilace} with --disable-pthreads.

A rebuild in debian revealed that this broke compilation of a number packages:
http://bugs.debian.org/cgi-bin/pkgreport.cgi?users=siretart@tauware.de;tag=ftbfs-libav0.8

Both the Indeo 4 decoder and the SMJPEG demuxer were included in the
0.8_beta1 release.

Codec timebase is not framerate and the situation when it's different
from AVStream.r_frame_rate is quite common, nothing to warn about.

Also fix calculation of new position when switching buffers.
This fixes "overread" error messages when seeking.

The fate-h264-bsf-mp4toannexb failures were caused by an integer
overflow of the unneeded multiplication.

None of the raw audio files have timestamps, thus setting
start_time to 0 should be reasonable.

The extra thread added in {frame_}*thread_init was not taken into
account. Explicitly sets thread_count to 1 if only one CPU core was
detected. Also fixes two typos in comments.

Palette is as supposed in native endianness. Converting the pal8 output
to rgb24 is thus necessary for identical CRCs on big and little endian
systems.

Some external codecs have their own code to determine the best number
of threads. This number is not necessary the number of cpu cores.
Thread_count will be only 0 if the codec has CODEC_CAP_AUTO_THREADS.

The safe bitstream reader does not allow using skip_bits_long() to seek to a
point before the start of the buffer, which was needed by the mp3 decoder.
This change instead calculates the start point of the first valid granule and
skips to that position.

Can act as fallback and should work on a couple of Unix systems.

Since the conditions for the actual usage are more specific a less
preferred method can be used. This would cause compilation errors
because necessary headers are not included.

Indeo 4 decoder and SMJPEG demuxer are not included in 0.8_beta1. Move
them to version <next>.
