This reverts commit 691dec6201.
The commit did not fix ticket #3215, it was fixed one commit earlier.
The revert may break other use-cases but they should be fixed differently,
the offending commit introduced too many problems.
Fixes ticket #3377.
Fixes ticket #3378.

libzvbi-teletextdec: split dvb packet to slices
libzvbi-teletextdec: use av_dlog where possible

Based on the aarch64 asm. CPU cycle counts on cortex-a9 compared to
gcc 4.8.2:
before: 475 decicycles in get_cabac_noinline, 67106035 runs, 2829 skips
after: 393 decicycles in get_cabac_noinline, 67106474 runs, 2390 skips
Overall speedup is above 2%. Code generated by clang 3.4 is slower on
the same hardware and the relative change is a little larger.
Based on the x86 branchless get_cabac asm. get_cabac_noinline() gets
approximately 20% faster (no cycle counts available) compared to clang
from Xcode 5.1 beta5. More than 6% faster overall. A part of the overall
speedup might be explained by additional inlining of get_cabac().
Instead of using the demux function of libzvbi to split the packet to slices
(vbi lines), lets do it ourselves.
- eliminates the 1 frame delay between page input and output
- handles non-ascending line numbers more gracefully
- enables us to return error codes on some invalid packets instead of silently
ignoring them

The overread avoidance fix in cbddee1cca
broke the computation for the last row since it prevented the safe
reading from the height+1-th row.

Old Intel GPUs expect the reference frame index to the actual surface,
instead of the index into RefFrameList as specified by the spec.
This workaround should be set when using one of the "ClearVideo" decoder
devices.

The latest H.264 DXVA specification states that the index in this
structure should refer to a valid entry in the RefFrameList of the picture
parameter structure, and not to the actual surface index.
Fixes H.264 DXVA2 decoding on recent Intel GPUs (tested on Sandy and Ivy)

Some content requires an higher number of slices in order to
render properly.
Rise the number to 1024 and warn if ever it exceeds.

The SVQ3 decoder reuses large parts of the H.264 decoder so it
makes no sense to enable the former but not the latter.
Also drop unnecessary h263.o object from SVQ3 decoder object list.
