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().

Was missed in aeaf268e when integrating
clear_blocks into the idct.

The overread avoidance fix in cbddee1c
broke the computation for the last row since it prevented the safe
reading from the height+1-th row.

Based on a suggestion by Martin Panter. This is more descriptive,
since it's the actual timestamp field from the RTMP packet,
which might or might not be a delta depending on context (in
some packets it's a delta, in some packets it's an absolute
timestamp, and in some packets it's 0xffffff to indicate that
the actual delta or absolute timestamp is transmitted separately).

Related fix in "rtmpdump":
https://repo.or.cz/w/rtmpdump.git/commitdiff/79459a2

Adobe's RTMP specification (21 Dec 2012), section 5.3.1.3 ("Extended
Timestamp"), says "this field is present in Type 3 chunks". Type 3 chunks are
those with the one-byte header size.

This resolves intermittent hangs and segfaults caused by the read function,
and also includes an untested fix for the write function.

The read function was tested with ABC (Australia) News 24 streams, however
they are probably restricted to only Australian internet addresses. Some of
the packets at the start of these streams seem to contain junk timestamp
fields, often requiring the extended field. Test command:

Some content requires an higher number of slices in order to

Rise the number to 1024 and warn if ever it exceeds.

Get the last partition offset and use it when footer partition

Footer partition may not be present and even if present footer

Extrapolate audio timestamps based on the number of samples demuxed.

Deal with some MXF nastiness involving fractional number of
samples per EditUnit when seeking (the specs handwave this away).

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.

This avoids checking inline/external assembly dependencies for x86
extensions that do not play a role in inline/external assembly.

They are TYPE_INT AVOptions, so they must be ints

Some optimized functions reference optimized symbols, so the functions
must be explicitly disabled when those symbols are unavailable.

The s390 architecture requires shared libraries to be built in PIC mode.
Otherwise applications will get wrong relocations at run-time, leading
