* OpebBSD: remove socketpair() for AF_INET and AF_INET6.
socketpair() is only supported on AF_UNIX.
* NetBSD: remove socketpair() for AF_INET and AF_INET6.
socketpair() is only supported for AF_UNIX.
* FreeBSD: remove socketpair() for AF_INET and AF_INET6.
socketpair() only supports AF_UNIX.
* Linux: remove socketpair for AF_INET and AF_INET6.
socketpair only supports AF_UNIX.
* Autogenerated files.
These are manually generated for all platforms you are not
running on. FreeBSD in this case.
* executor: rebase.
* sys/freebsd: rebase.
* sys/linux: use AF_UNIX based socketpair for nbd.
This was suggested by Dmitry.
Fixes#845
1. Add size attribte on sockaddr.
2. Remove sockaddr's that are larger than 16 bytes from sockaddr.
3. Add size attribute on sockaddr_storage which wasn't actually 128 bytes.
4. Add size attribute to ifreq.
5. Fix ifmap field types as uncovered by the size attributes.
6. Fix sockaddr_storage_tcp from struct to union which is should be.
7. Make sockaddr_un_file fixed size as it should be.
8. Fix some explicit paddings that were only correct for 64 bits.
We currently print unsupported consts to console during make extract.
But this is not very useful as there are too many output now.
This also does not allow to understand what's unsupported
in newly checked-in descriptions, or what's unsupported in all current
decriptions.
Save unsupported consts to the const files instead.
This solves all of the above problems.
