FreeBSD support NX bit on X86_64 processors out of the box, for i386 emulation use READ_IMPLIES_EXEC flag, introduced in r302515. While here move common part of mmap() and mprotect() code to the files in compat/linux to reduce code dupcliation between Linuxulator's. Reported by: Johannes Jost Meixner, Shawn Webb MFC after: 1 week XMFC with: r302515, r302516
