that is committed.

Note: memory handling likely could be rewritten to use q_autofree. That
will be explored in the future since what we have now works well enough.

54ee5b3da0 util/log: Drop manual log buffering
This buffering was introduced during the Paleozoic: 9fa3e85353.

There has never been an explanation as to why we may not allow
glibc to allocate the file buffer itself.  We certainly have
many other uses of mmap and malloc during user-only startup,
so presumably whatever the issue was, it has been fixed during
the preceeding 18 years.

e555e709bb bsd-user/arm/target_arch_cpu.h: Only support FreeBSD sys calls
Since we don't build on OpenBSD, only do FreeBSD system calls here. In
the future, we'll need to move this to some place like
bsd-user/freebsd/arm/mumble.h, but until then just leave this
inline. This reflects changes to the upstream.

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.

872b349f61 bsd-user/x86_64/target_arch_cpu.h: int $80 never was a BSD system call on amd64
Although initial versions of NetBSD did use int $80, it was replaced by
syscall before any releases. OpenBSD and FreeBSD always did syscall.

d19401825d bsd-user/main.c: Drop syscall flavor arg -bsd
We've not realistically been able to actually run any bsd program on any
other bsd program. They are too diverged to do this easily. The current
code is setup to do it, but implementing it is hard. Stop pretending
that we can do this.

cd6174843b exec/exec-all: Move 'qemu/log.h' include in units requiring it
Many files use "qemu/log.h" declarations but neglect to include
it (they inherit it via "exec/exec-all.h"). "exec/exec-all.h" is
a core component and shouldn't be used that way. Move the
"qemu/log.h" inclusion locally to each unit requiring it.

The capsicum signal stuff is new with FreeBSD 14, rev 1400026, so only
define QEMU_SI_CAPSICUM there. Only copy _capsicum when QEMU_SI_CAPSICUM
is defined. Default to no info being passed for signals we make no guess
about.
