Also remove ff_smil_extract_next_chunk - this was the last user of it.

ff_smil_extract_next_chunk() is still used by RealText.

Use the UTF-16 BOM to detect UTF-16 encoding. Convert the file contents
to UTF-8 on the fly using FFTextReader, which acts as converting wrapper
around AVIOContext. It also can work on a static buffer, needed for
format probing. The FFTextReader wrapper now also takes care of skipping
the UTF-8 BOM.

Fix Ticket #3496.

This is more portable and avoids warnings with compilers that do not
properly support av_unused.

This avoids an unused variable warning with hardcoded tables.

paddq is an SSE2 instruction so it cannot be used for MMX.

This was probably just a typo because the sums are dwords anyway.
