3bd062bf7f vp3: Use hpeldsp instead of dsputil for half-pel functions
This makes vp3 independent of dsputil.

015821229f vp3: Use full transpose for all IDCTs
This way, the special IDCT permutations are no longer needed. This
is similar to how H264 does it, and removes the dsputil dependency
imposed by the scantable code.

Also remove the unused type == 0 cases from the plain C version
of the idct.

18df366a18 vp3: Embed idct_permutation array directly in VP3DecoderContext
This makes the vp3 decoder less dependent on dsputil, and will aid
in making it (eventually) dsputil-independent.

4a73fbd9c5 vp3/5: move put_no_rnd_pixels_l2 from dsputil to VP3DSPContext.
The function is only used in VP3 and VP5, so no need to have it in
DSPContext.

aeaf268e52 vp3: integrate clear_blocks with idct of previous block.
This is identical to what e.g. vp8 does, and prevents the function call
overhead (plus dependency on dsputil for this particular function).

e33db35b4a theora: Skip zero-sized headers
This fixes a regression since d9cf5f51 with theora over RTP
(possibly with other variants of theora as well).

In theora over RTP, the second of the 3 headers turns out to be
0 bytes long, which prior to d9cf5f51 worked just fine. After
d9cf5f51, reading from the bitstream reader fails (since the reader
wasn't initialized but returned an error if initialized with 0 bits).

8c53d39e7f lavc: introduce VideoDSPContext
Move some functions from dsputil. The idea is that videodsp contains
functions that are useful for a large and varied set of video decoders.
Currently, it contains emulated_edge_mc() and prefetch().

737eb5976f Merge libavcore into libavutil
It is pretty hopeless that other considerable projects will adopt
libavutil alone in other projects. Projects that need small footprint
are better off with more specialized libraries such as gnulib or rather
just copy the necessary parts that they need. With this in mind, nobody
is helped by having libavutil and libavcore split. In order to ease
maintenance inside and around FFmpeg and to reduce confusion where to
put common code, avcore's functionality is merged (back) to avutil.
