The lookahead_thread main loop checks b_exit_thread and exits if it is set.
That flag is set by x264_lookahead_delete, which uses ifbuf.mutex to guard accessing it.
However, the read in the while-loop condition of lookahead_thread is not guarded,
and so TSAN sometimes reports a data race.

This fixes rerunning checkasm with an earlier printed seed, when
it's outside of the signed range.

This includes fixing convert_method_to_flag so it recognizes "gauss"
parameter properly instead of silently defaulting to bicubic.

Particularly in code that makes heavy use of macros it's possible
to end up with 3-operand instructions with a memory operand in src1.
In the case of SSE this works fine due to automatic move insertions,
but in AVX that fails since memory operands are only allowed in src2.

The main purpose of this feature is to minimize the amount of code
changes required to facilitate conversion of existing SSE code to AVX.

Compilers are good at optimizing multiplication by shift.

Use --cll to specify the maximum content light level (MaxCLL)
and the maximum frame average light level (MaxFALL) as described
by the CTA 861.3 specification.

Use --mastering-display to specify the properties of the reference display.
A formatted string with all 10 values is required: G,B,R primaries and
white point coordinates, plus max/min brightness. Coordinates are in
0.00002 increments. Brightness units are 0.0001 cd/m^2.

For example, a 1000 nit BT.2020 display with a 0.0001 nit black level:
--mastering-display G(13250,34500)B(7500,3000)R(34000,16000)WP(15635,16450)L(10000000,1)

On modern versions of OpenBSD, the number of processors online may differ from
the number of processors configured.

Use 'cmhs' (which does an unsigned greater or equal comparison)
instead of 'cmhi' (which does an unsigned greater comparison).

This makes sure that dct coeffs with a magnitude of 1 are recognized
in the output nnz buffer.

Large stack allocations on Windows need to use stack probing in order
to guarantee that all stack memory is committed before accessing it.
This is done by ensuring that the guard page(s) at the end of the
currently committed pages are touched prior to any pages beyond that.

Bug report by Zhengzhi Duan.

Make pointers to padded buffers aligned both before and after padding.

In 10-bit mode pixel_asd8 expects 16-byte alignment for pix1 and pix2.

It's not required, and BSD doesn't support it.
