2023 Q1 bsd-user upstreaming: bugfixes and sysctl

[ letter edited -- need reviews for these hunks
     bsd-user: Helper routines h2g_old_sysctl
     bsd-user: various helper routines for sysctl
]

This group of patches gets the basic framework for sysctl upstreamed. There's a
lot more to translate far too many binary blobs the kernel publishes via
sysctls, but I'm leaving those out in the name of simplicity.

There's also a bug fix from Doug Rabson that fixes a long int confusion leading
to a trunctation of addresses (oops)

There's a fix for the -static option, since clang hates -no-pie and needs only
-fno-pie.

Finally, I'm changing how I'm upstreaming a little. I'm doing a little deeper
dives into our rather chaotic repo to find a couple of authors I might have
missed. From here on out, I'll be using the original author's name as the git
author. I'll also tag the co-authors better as well when there's multiple people
that did something (other than reformat and/or move code around). I've
discovered more code moved about than I'd previously known. This seems more in
line with standard practice.

v3->pull:
o minor tweaks in the conditional reviews around formatting
o fix all errors for check patch and am OK with remaining warnings for
  line length that's only slightly too long
o edited letter for changes in review process

v3:
o Removed -strict, it's not ready and needs a complete rethink.
o Add g_assert_not_reached()
o target -> guest in most places
o Use MIN() to simplify things
o Better types in many places (abi_int instead of int32_t)
o Use ARRAY_COUNT
o fix tabs copied from FreeBSD sources to spaces

v2:
o Created various helper functions to make the code a little better
o split a few patches that I thought would be approved together but
  that generated commentary. It's easier to manage 1 per patch for
  those.
o Add/delete G_GNU_UNUSED to ensure all patches compile w/o warnings
o Fix 64-bit running 32-bit binary to get a LONG or ULONG. Add a
  bounce buffer for these so we don't overflow anything on the target
  and return all the elements of arrays.
o Fixed a number of nits noticed in the review.
o Add or improve comments to explain things there were questions on
  during the review.
o fix noted typos
o fix host != target page size differences
o Add pointers to FreeBSD source code, as appropriate
o fix locking (mostly unlocking) on error paths
o Note: -strict feedback not yet applied due to large numbers of changes
  from the rest. Next round.

target/ppc: Restrict 'qapi-commands-machine.h' to system emulation

Since commit a0e61807a3 ("qapi: Remove QMP events and commands from
user-mode builds") we don't generate the "qapi-commands-machine.h"
header in a user-emulation-only build.

Move the QMP functions from cpu_init.c (which is always compiled)
to monitor.c (which is only compiled when system-emulation
is selected).  Rename monitor.c to arm-qmp-cmds.c.

Note ppc_cpu_class_by_name() is used by both file units, so we

[Straightforward conflict with commit 9def656e7a2 resolved]

readline: fix hmp completion issue

The auto completion does not work in some cases.

Case 1.

1. (qemu) info reg
2. Press 'Tab'.
3. It does not auto complete.

Case 2.

1. (qemu) block_resize flo
2. Press 'Tab'.
3. It does not auto complete 'floppy0'.

Since the readline_add_completion_of() may add any completion when
strlen(pfx) is zero, we remove the check with (name[0] == '\0') because
strlen() always returns zero in that case.

tb-jmp-cache.h contains a few small functions that only exist to hide a
CF_PCREL check, however the caller often already performs such a check.

This patch moves CF_PCREL checks from the callee to the caller, and also
removes these functions which now only hide an access of the jmp-cache.

Merge branch 'xenfv-kvm-15' of git://git.infradead.org/users/dwmw2/qemu into HEAD

This adds support for emulating Xen under Linux/KVM, based on kernel
patches which have been present since Linux v5.12. As with the kernel
support, it's derived from work started by João Martins of Oracle in
2018.

This series just adds the basic platform support — CPUID, hypercalls,
event channels, a stub of XenStore.

A full single-tenant internal implementation of XenStore, and patches
to make QEMU's Xen PV drivers work with this Xen emulation, are waiting
in the wings to be submitted in a follow-on patch series.

As noted in the documentation, it's enabled by setting the xen-version
property on the KVM accelerator, e.g.:

 qemu-system-x86_64 -serial mon:stdio -M q35 -display none -m 1G -smp 2 \
    -accel kvm,xen-version=0x4000e,kernel-irqchip=split \
    -kernel vmlinuz-6.0.7-301.fc37.x86_64 \
    -append "console=ttyS0 root=/dev/sda1" \
    -drive file=/var/lib/libvirt/images/fedora28.qcow2,if=none,id=disk \
    -device ahci,id=ahci -device ide-hd,drive=disk,bus=ahci.0

Even before this was merged, we've already been using it to find and fix
bugs in the Linux kernel Xen guest support:
