63fd8ef080 target/i386: implement SYSCALL/SYSRET in 32-bit emulators
AMD supports both 32-bit and 64-bit SYSCALL/SYSRET, but the TCG only
exposes it for 64-bit targets.  For system emulation just reuse the
helper; for user-mode emulation the ABI is the same as "int $80".

The BSDs does not support any fast system call mechanism in 32-bit
mode so add to bsd-user the same stub that FreeBSD has for 64-bit
compatibility mode.

9c0928045c Clean up ill-advised or unusual header guards
Leading underscores are ill-advised because such identifiers are
reserved.  Trailing underscores are merely ugly.  Strip both.

Our header guards commonly end in _H.  Normalize the exceptions.

Macros should be ALL_CAPS.  Normalize the exception.

Done with scripts/clean-header-guards.pl.

include/hw/xen/interface/ and tools/virtiofsd/ left alone, because
these were imported from Xen and libfuse respectively.

8f4b48164f bsd-user/i386/target_arch_cpu.h: Remove openbsd syscall
This doesn't build on openbsd at the moment, and this could
should arguably be in bsd-user/*bsd/i386 somewhere. Until
we refactor to support OpenBSD/NetBSD again, drop it here.
