eebe406c80 libswscale: Test AV_CPU_FLAG_SLOW_GATHER for hscale functions.
This is instead of EXTERNAL_AVX2_FAST so that the avx2 hscale functions
are only used where they are faster.

3f4ce004b8 swscale/input: clip rgbf32 values before lrintf
if the float pixel * 65535.0f > 2147483647.0f
lrintf may overfow and return negative values, depending on implementation.
nan and +/-inf values may also be implementation defined

clip the value first so lrintf always works.

values <     0.0f, -inf, nan = 0.0f
values > 65535.0f, +inf      = 65535.0f

f440c422b7 swscale/swscale: Fix races when using unaligned strides/data
In this case the current code tries to warn once; to do so, it uses
ordinary static ints to store whether the warning has already been
emitted. This is both a data race (and therefore undefined behaviour)
as well as a race condition, because it is really possible for multiple
threads to be the one thread to emit the warning. This is actually
common since the introduction of the new multithreaded scaling API.

This commit fixes this by using atomic integers for the state;
furthermore, these are not static anymore, but rather contained
in the user-facing SwsContext (i.e. the parent SwsContext in case
of slice-threading).

Given that these atomic variables are not intended for synchronization
at all (but only for atomicity, i.e. only to output the warning once),
the atomic operations use memory_order_relaxed.

This affected the nv12, nv21, yuv420, yuv420p10, yuv422, yuv422p10 and
yuv444 filter-overlay FATE-tests.
