Add preliminary support for running 32-bit Linux binaries on amd64, enabled with the COMPAT_LINUX32 option. This is largely based on the i386 MD Linux emulations bits, but also builds on the 32-bit FreeBSD and generic IA-32 binary emulation work. Some of this is still a little rough around the edges, and will need to be revisited before 32-bit and 64-bit Linux emulation support can coexist in the same kernel.

To reduce code duplication introduce linux_copyout_rusage() method. Use it in linux_wait4() system call and move linux_wait4() to the MI path. While here add a prototype for the static bsd_to_linux_rusage(). Differential Revision: https://reviews.freebsd.org/D2138 Reviewed by: trasz

Implement vdso - virtual dynamic shared object. Through vdso Linux exposes functions from kernel with proper DWARF CFI information so that it becomes easier to unwind through them. Using vdso is a mandatory for a thread cancelation && cleanup on a modern glibc. Differential Revision: https://reviews.freebsd.org/D1060

Segment registers are stored in the uc_mcontext member of the struct l_ucontext. To restore the registers content, trampoline needs to dereference uc_mcontext instead of taking some undefined values from l_ucontext. Submitted by: Dmitry Chagin <dchagin@> MFC after: 1 week
