Move the table to a common file to be used by all. Make it 'const int' to place it in .rodata. (Some existing Linux architectures use MD errno values, but x86 and Arm share the generic set.) This change should introduce no functional change; a followup will add missing errno values. MFC r331057: linux_errno.c: add newer errno values Also introduce a static assert to ensure the list is kept up to date.

When compiling with link-time optimization (LTO) using -flto, .o files are LLVM bitcode, not ELF objects. This is not usable by genassym.sh, so remove -flto from those ${CC} invocations.

FreeBSD support NX bit on X86_64 processors out of the box, for i386 emulation use READ_IMPLIES_EXEC flag, introduced in r302515.

Linux sigset always 64 bit on all platforms. In order to move Linux sigset code to the linux_common module define it as 64 bit int. Move Linux sigset manipulation routines to the MI path. 2. Move Linux signal number definitions to the MI path. In general, they are the same on all platforms except for a few signals. 3. Map Linux RT signals to the FreeBSD RT signals and hide signal conversion tables to avoid conversion errors. 4. Emulate Linux SIGPWR signal via FreeBSD SIGRTMIN signal which is outside of allowed on Linux signal numbers.

The kqueue user data are 32bit on i386 which is not enough for epoll user data, so we keep user data in the proc emuldata. Initial patch developed by rdivacky@ in 2007, then extended by Yuri Victorovich @ r255672 and finished by me in collaboration with mjg@ and jillies@.

As we can have both 64 & 32 bit Linuxulator running any eventhandler can be called twice for us. To prevent this move eventhandlers code from linux_emul.c to the linux_common.ko module.
