- print out the PID and program name of the program trying to use an unsupported futex operation - for those futex operations which are known to be not supported, print out which futex operation it is - shortcut the error return of the unsupported FUTEX_CLOCK_REALTIME in some cases: FUTEX_CLOCK_REALTIME can be used to tell linux to use CLOCK_REALTIME instead of CLOCK_MONOTONIC. FUTEX_CLOCK_REALTIME however must only be set, if either FUTEX_WAIT_BITSET or FUTEX_WAIT_REQUEUE_PI are set too. If that's not the case we can die with ENOSYS right at the beginning.

Merge linux emulation parts for video4linux support (requires a native v4l device, e.g. something which works with ports://multimedia/webcamd).

Replace the static NGROUPS=NGROUPS_MAX+1=1024 with a dynamic kern.ngroups+1. kern.ngroups can range from NGROUPS_MAX=1023 to somewhere in the neighborhood of INT_MAX/4 one a system with sufficent RAM and memory bandwidth. Given that the Windows group limit is 1024, this range should be sufficient for most applications r202342: Only allocate the space we need before calling kern_getgroups instead of allocating what ever the user asks for up to "ngroups_max + 1". On systems with large values of kern.ngroups this will be more efficient. The now redundant check that the array is large enough in kern_getgroups() is deliberate to allow this change to be merged to stable/8 without breaking potential third party consumers of the API.

- Return EAFNOSUPPORT instead of EINVAL for unsupported address family, this matches the Linux behavior. - Check if we have sufficient space allocated for socket structure, which fixes a buffer overflow when wrong length is being passed into the emulation layer.
