Consolidates it in a one place. Fixup loopback interface names translation and use ifnet methods and accessors, where possible.

At least POLLRDHUP is handled by FreeBSD differently than by Linux. Seems that Linux silencly ignores POLLRDHUP on non socket fd's unlike FreeBSD, which does more strictly check and fails. Rework the Linux ppoll, using kern_poll and converting 'events' and 'revents' values. While here, move poll events defines to the MI part of code as they mostly identical on all arches except arm.

That's the minimum 3 of copyin/copyout operations for one syscall. Also some syscall uses linux_sa_put() and linux_getsockaddr() when load sockaddr to userspace or from userspace accordingly. To avoid this chaos, especially converting sockaddr in the userspace, rewrite these 4 functions to convert sockaddr only in kernel and leave only 2 of this functions. Also in order to reduce duplication between MD parts of the Linuxulator put struct sockaddr conversion functions that are MI out into linux_common module.

For that remove bogus _packed attribute from struct l_sockaddr and use MI types for struct members. And continue to move into the linux_common module a code that is intended for both Linuxulator modules (both instruction set - 32 & 64 bit) or for external modules like linsysfs or linprocfs. To avoid header pollution introduce new sys/compat/linux_common.h header. Reviewed by: emaste MFC after: 2 weeks Differential Revision: https://reviews.freebsd.org/D20137
