Full range video had been broken by the introduction of the < 2U check
at the following line. The bitstream format kind of implies that the full
and limited ranges use different pix_fmts but that's incorrect since we
have the avctx->color_range flag. So adjust the pixel range index to
be mapped to the same pix_fmts as limited range index.

adds two new options that may be set via the dictionary:
- send_buffer_size
- recv_buffer_size
When present, setsockopt() is used with SO_SNDBUF and SO_RCVBUF to set
socket buffer sizes. I chose to make send and receive independent
because buffering requirements are often asymmetric.
Errors in setting the buffer size mean the socket will use its
default, so they are ignored.
There is no sanity checking on values, as the kernel/socket layers
already impose reasonable limits if asked for something crazy.
Rationale for enlarging receive buffers is to reduce susceptibility
to intermittent network delays/congestion. I added setting the send
buffer for symmetry.

Previously the full source path was embedded inconsistently in the debug
information between in-tree/out-of-tree builds.
The 'vpath %.inc' becomes necessary for finding
libavfilter/all_channel_layouts.inc in out-of-tree builds.
The full source path is still embedded in the debug information, but
it's now independent of whether building in-tree or out-of-tree.
The biggest improvement of this patch is that gdb now always searches
for the path relative to the source directory. It still also searches
for the full path.
Previously it searched only for the full path in out-of-tree builds,
making the debug information generated by Debian's buildds rather hard
to use.

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.
This option is only used by mpegvideoenc and openh264.
It is a very codec-specific option, so deprecate the global variant.
The openh264 option is dropped altogether since it is just a fallback
for -max_nal_size anyway.

Add an allowed value to the private options for frame_skip_cmp which
seems to have been forgotten, but perfectly working.
The libvpx frame dropping feature uses one of such option
(frame_skip_threshold) without the other three. For this reason rename
the option to something more consistent with the other libvpx variables.
