buffersrc: avoid using AV_PIX_FMT_NB
...
That hardcodes the number of pixel formats into lavfi and will break
when a shared lavu is updated, adding new pixel formats.

lavfi: add attribute_align_arg to all public entry points
...
Previously it was partly only added to central functions called
internally, however if GCC would inline these into the public fuction, the
alignment attribute would not take effect.
Instead, add it to all public entry points to avoid these problems.

lavfi: let gcc realign the stack on public graph driving functions
...
The functions which actually drive the filter graph by pushing
frames through it need to ensure an aligned stack for SIMD functions.
This fixes a crash in YADIF filter when using a mingw build in a MSVC
application.

lavfi/buffersrc: fix failed requests count.
...
The line was lost during the AVFrame transition.
It causes programs relying on the failed requests count,
especially ffmpeg, to add frames to the wrong input.

lavfi/buffersrc: implement flags.
...
The PUSH flags is necessary for efficient scheduling;
otherwise there is no feedback when adding frames to
closed paths.
The NO_CHECK_FORMAT is a small optimization that does
not cost much to implement.
The KEEP_REF flag maps to the add/write distinction in
the fork's API.

If buffersrc was configured for frames with an unknown layout,
the incoming frames will have channel_layout = 0.
If the format negotiation has selected a known (and compatible)
channel layout for the link, the frame is assumed to have
that layout, the field must be set before injecting the frame
in the filters.
