ucNumDeltaPocsOfRefRpsIdx needs to contain the flat value from the SPS RPS,
and not the final computed value from the slice header RPS, as this calculation
is done internally by the driver again.

If an input file is bigger than 2GB (assume sizeof(int) == 4)),
size0/size1 will overflow, making stddev and PSNR invalid.

lavfi has been considered to be stable for a while now, so it is enabled
in most configurations. Supporting avplay without lavfi requires a lot
of nontrivial ifdef mess for no good reason.
This fixes infinite loops due to seeking back.

asf_read_payload can unset eof_reached, so check it also before calling
that function.

The private options chromaoffset, sc_threshold, and noise_reduction
were set to 0 rather than -1, and were always initializing values
in libx264 rather than letting the library use its default.

AVX2 support was introduced in Yasm 1.2.0 and NASM 2.10, and the
oldest versions currently supported are Yasm 0.8.0 and NASM 2.03

Some (de)muxers open additional files beyond the main IO context.
Currently, they call avio_open() directly, which prevents the caller
from using custom IO for such streams.
This commit adds callbacks to AVFormatContext that default to
avio_open2()/avio_close(), but can be overridden by the caller. All
muxers and demuxers using AVIO are switched to using those callbacks
instead of calling avio_open()/avio_close() directly.
(de)muxers that use the URLProtocol layer directly instead of AVIO
remain unconverted for now. This should be fixed in later commits.
Some debuggers/profilers use this metadata to determine which function a
given instruction is in; without it they get can confused by local labels
(if you haven't stripped those). On the other hand, some tools are still
confused even with this metadata. e.g. this fixes `gdb`, but not `perf`.
Currently only implemented for ELF.

The REP_RET workaround is only needed on old AMD cpus, and the labels clutter
up the symbol table and confuse debugging/profiling tools, so use EQU to
create SHN_ABS symbols instead of creating local labels. Furthermore, skip
the workaround completely in functions that definitely won't run on such cpus.
Note that EQU is just creating a local label when using nasm instead of yasm.
This is probably a bug, but at least it doesn't break anything.

When allocating stack space with a larger alignment than the known stack
alignment a temporary register is used for storing the stack pointer.
Ensure that this isn't one of the registers used for passing arguments.

* Correctly handle FMA instructions with memory operands.
* Print a warning if FMA instructions are used without the correct cpuflag.
* Simplify the instantiation code.
* Clarify documentation.
Only the last operand in FMA3 instructions can be a memory operand. When
converting FMA4 instructions to FMA3 instructions we can utilize the fact
that multiply is a commutative operation and reorder operands if necessary
to ensure that a memory operand is used only as the last operand.
