FreeBSD has a system call number header, sys/syscall.h, that's installed
on every system that can compile qemu. Generate the system call numbers
from that table rather than re-regenerating it yet again.
To do this, I have to clean up a few stragglers for system calls we've
removed. But these returned not supported anyway, so there's no net
change.
I also tried to do this in a way that the other bsds can coexist with
should they show up again in the future. To that end, I moved the
definition of time_t into os-syscall.h, where I noticed it was wrong for
amd64 targets (which is little used and missing features, so it went
unnoticed for a long time).
More will be generated in the future, but this is the first steps.

Per out policy we only aim to support the 2 most recent major versions of distros: https://www.qemu.org/docs/master/about/build-platforms.html So for FreeBSD that means 14.x and 15.x series are all that you need to retain code support for.

I don't even know why there was code to implement them in the first place. In fact, digging deeper, 4.3-Reno returns not supported. 4.3-Tahoe had them stubbed out as blank (no error, but did nothing), like 4.3BSD and 4.2BSD did before it.

I just #ifdef'd them because I wasn't sure, but now I am...

Berrangé, Philippe Mathieu-Daudé, Warner Losh Now that this will build and work, remove the old syscall_nr.h and switch the include over to the generated file in syscall_defs.h. To do this, I had to delete the old, wrong definition of time_t for FreeBSD on amd64 since it stumbled over the fact that TARGET_i386 is defined for both 32-bit and 64-bit builds (the new os-syscall.h had the rigth definition). Rather than modify this file twice to fix it, rolled the fix into using os-syscall.h since it's still easy enough to review.
