Was "[PATCH] libx264: Do not explicitly set X264_API_IMPORTS"

Setting X264_API_IMPORTS only affects msvc builds and it breaks
linking to static builds (although is required for shared builds).
This flag is set by x264 in its pkgconfig as required since build
158 (a615f027ed172e2dd5380e736d487aa858a0c4ff) from July 2019.
So this patch updates configure to require a newer x264 build that
correctly sets the imports flag.

The requirement for 158 is applied for msvc builds only,
no change is made for all other cases.

    libx264: Set min build version to 158
    
    I'm submitting this patch on behalf of Matt with his permission.
    
    There was agreement that the >= 158 version requirement should be
    applied to MSVC builds only.
    
    v2: restrict the version requirement to msvc builds

     -    Alternatively we can detect the x264 build version in configure
     -    and keep the fallback of manually setting the flag on older x264
     -    builds that arent using pkgconfig (to keep the old behaviour) but
     -    that requires some complex configure changes.
     +    The requirement for 158 is applied for msvc builds only,
     +    no change is made for all other cases.
