Move most of the contents of opt_compat.h to opt_global.h.opt_compat.h is mentioned in nearly 180 files. In-progress networkdriver compabibility improvements may add over 100 more so this isclose
Move most of the contents of opt_compat.h to opt_global.h.opt_compat.h is mentioned in nearly 180 files. In-progress networkdriver compabibility improvements may add over 100 more so this iscloser to "just about everywhere" than "only some files" per theguidance in sys/conf/options.Keep COMPAT_LINUX32 in opt_compat.h as it is confined to a subset ofsys/compat/linux/*.c. A fake _COMPAT_LINUX option ensure opt_compat.his created on all architectures.Move COMPAT_LINUXKPI to opt_dontuse.h as it is only used to control theset of compiled files.Reviewed by: kib, cem, jhb, jtlSponsored by: DARPA, AFRLDifferential Revision: https://reviews.freebsd.org/D14941

Add support for Intel Software Guard Extensions (Intel SGX).Intel SGX allows to manage isolated compartments "Enclaves" in user VAspace. Enclaves memory is part of processor reserved memory (PRM) andalways encrypted. This allows to protect user application code and datafrom upper privilege levels including OS kernel.This includes SGX driver and optional linux ioctl compatibility layer.Intel SGX SDK for FreeBSD is also available.Note this requires support from hardware (available since late IntelSkylake CPUs).Many thanks to Robert Watson for support and Konstantin Belousovfor code review.Project wiki: https://wiki.freebsd.org/Intel_SGX.Reviewed by: kibRelnotes: yesSponsored by: DARPA, AFRLDifferential Revision: https://reviews.freebsd.org/D11113
