Add support for Intel Software Guard Extensions (Intel SGX). Intel SGX allows to manage isolated compartments "Enclaves" in user VA space. Enclaves memory is part of processor reserved memory (PRM) and always encrypted. This allows to protect user application code and data from 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 Intel Skylake CPUs). Many thanks to Robert Watson for support and Konstantin Belousov for code review. Project wiki: https://wiki.freebsd.org/Intel_SGX.

Move assym.s to DPSRC in sgx module assym.s is only to be included by other .s files, and should not actually be assembled by itself. 2018-03-16 13:33:42 +00:00			`SRCS= sgx.c sgxvar.h sgx_support.S`
Move most of the contents of opt_compat.h to opt_global.h. opt_compat.h is mentioned in nearly 180 files. In-progress network driver compabibility improvements may add over 100 more so this is closer to "just about everywhere" than "only some files" per the guidance in sys/conf/options. Keep COMPAT_LINUX32 in opt_compat.h as it is confined to a subset of sys/compat/linux/*.c. A fake _COMPAT_LINUX option ensure opt_compat.h is created on all architectures. Move COMPAT_LINUXKPI to opt_dontuse.h as it is only used to control the set of compiled files.
