util: Remove redundant checks in the openpty()
As we can see from the following function call stack, amaster and aslave
can not be NULL: char_pty_open() -> qemu_openpty_raw() -> openpty().
In addition, according to the API specification for openpty():
https://www.gnu.org/software/libc/manual/html_node/Pseudo_002dTerminal-Pairs.html,
the arguments name, termp and winp can all be NULL, but arguments amaster or aslave
can not be NULL.
Finally, amaster and aslave has been dereferenced at the beginning of the openpty().
So the checks on amaster and aslave in the openpty() are redundant. Remove them.

gitlab-ci: Make more custom runner jobs manual, and don't allow failure
Currently we define a lot of jobs for our custom runners:
for both aarch64 and s390x we have
- all-linux-static
- all
- alldbg
- clang (manual)
- tci
- notcg (manual)
This is overkill. The main reason to run on these hosts is to get
coverage for the host architecture; we can leave the handling of
differences like debug vs non-debug to the x86 CI jobs.
The jobs are also generally running OK; they occasionally fail due to
timeouts, which is likely because we're overloading the machine by
asking it to run 4 CI jobs at once plus the ad-hoc CI.
Remove the 'allow_failure' tag from all these jobs, and switch the
s390x-alldbg, aarch64-all, s390x-tci and aarch64-tci jobs to manual.
(We keep -all on s390x and -alldbg on aarch64 just for diversity
of coverage.)
This will let us make the switch for s390x and aarch64 hosts from
the ad-hoc CI to gitlab.

chardev: Propagate error from logfile opening
If a chardev has a logfile the file is opened using
qemu_open_old() which does the job, but since @errp is not
propagated into qemu_open_internal() we lose much more accurate
error and just report "Unable to open logfile $errno". When
using plain files, it's probably okay as nothing complex is
happening behind the curtains. But the problem becomes more
prominent when passing an "/dev/fdset/XXX" path since much more
needs to be done.
The fix is to use qemu_create() which passes @errp further down.

hw/arm/mps2-tz.c: Add extra data parameter to MakeDevFn
The mps2-tz boards use a data-driven structure to create the devices
that sit behind peripheral protection controllers. Currently the
functions which create these devices are passed an 'opaque' pointer
which is always the address within the machine struct of the device
to create, and some "all devices need this" information like irqs and
addresses.
If a specific device needs more information than this, it is
currently not possible to pass that through from the PPCInfo
data structure. Add support for passing an extra data parameter,
so that we can more flexibly handle the needs of specific
device types. To provide some type-safety we make this extra
parameter a pointer to a union (which initially has no members).
In particular, we would like to be able to indicate which of the
i2c controllers are for on-board devices only and which are
connected to the external 'shield' expansion port; a subsequent
patch will use this mechanism for that purpose.

qdev: Support marking individual buses as 'full'
By default, QEMU will allow devices to be plugged into a bus up to
the bus class's device count limit. If the user creates a device on
the command line or via the monitor and doesn't explicitly specify
the bus to plug it in, QEMU will plug it into the first non-full bus
that it finds.
This is fine in most cases, but some machines have multiple buses of
a given type, some of which are dedicated to on-board devices and
some of which have an externally exposed connector for user-pluggable
devices. One example is I2C buses.
Provide a new function qbus_mark_full() so that a machine model can
mark this kind of "internal only" bus as 'full' after it has created
all the devices that should be plugged into that bus. The "find a
non-full bus" algorithm will then skip the internal-only bus when
looking for a place to plug in user-created devices.

In v8A, the PSTATE.IL bit is set for various kinds of illegal
exception return or mode-change attempts. We already set PSTATE.IL
(or its AArch32 equivalent CPSR.IL) in all those cases, but we
weren't implementing the part of the behaviour where attempting to
execute an instruction with PSTATE.IL takes an immediate exception
with an appropriate syndrome value.
Add a new TB flags bit tracking PSTATE.IL/CPSR.IL, and generate code
to take an exception instead of whatever the instruction would have
been.
PSTATE.IL and CPSR.IL change only on exception entry, attempted
exception exit, and various AArch32 mode changes via cpsr_write().
These places generally already rebuild the hflags, so the only place
we need an extra rebuild_hflags call is in the illegal-return

hw/misc: zynq_slcr: Correctly compute output clocks in the reset exit phase
As of today, when booting upstream U-Boot for Xilinx Zynq, the UART
does not receive anything. Debugging shows that the UART input clock
frequency is zero which prevents the UART from receiving anything as
per the logic in uart_receive().
From zynq_slcr_reset_exit() comment, it intends to compute output
clocks according to ps_clk and registers. zynq_slcr_compute_clocks()
is called to accomplish the task, inside which device_is_in_reset()
is called to actually make the attempt in vain.
Rework reset_hold() and reset_exit() so that in the reset exit phase,
the logic can really compute output clocks in reset_exit().
With this change, upstream U-Boot boots properly again with:
$ qemu-system-arm -M xilinx-zynq-a9 -m 1G -display none -serial null -serial stdio \
-device loader,file=u-boot-dtb.bin,addr=0x4000000,cpu-num=0

Merge remote-tracking branch 'remotes/bsdimp/tags/pull-bsd-user-
20210910' into staging
This series of patches gets me to the point that I can run "Hello World" on i386
and x86_64. This is for static binaries only, that are relatively small, but
it's better than the 100% instant mmap failre that is the current state of all
things bsd-user in upstream qemu. Future patch sets will refine this, add
the missing system calls, fix bugs preventing more sophisticated programms
from running and add a bunch of new architecture support.
There's three large themes in these patches, though the changes that
represent them are interrelated making it hard to separate out further.
1. Reorganization to support multiple OS and architectures (though I've only
tested FreeBSD, other BSDs might not even compile yet).
2. Diff reduction with the bsd-user fork for several files. These diffs include
changes that borrowed from linux-user as well as changes to make things work
on FreeBSD. The records keeping when this was done, however, was poor at
best, so many of the specific borrowings are going unacknowledged here, apart
from this general ack. These diffs also include some minor code shuffling.
Some of the changes are done specifically to make it easier to rebase
the bsd-user fork's changes when these land in the tree (a number of changes
have been pushed there to make this more possible).
3. Filling in the missing pieces to make things work. There's many changes to
elfload to make it load things in the right places, to find the interpreter
better, etc. There's changes to mmap.c to make the mappings work better and
there's changes to main.c that were inspired, at least, by now-ancient changes
to linux-user's main.c.
I ran checkpatch.pl on this, and there's 350-odd errors it identifies (the vast
majoirty come from BSD's fetish for tabs), so there will need to be a V2 to fix
this at the very least. In addition, the change set is big (about +~4.5k/-~2.5k
lines), so I anticipate some iteration as well just based on its sheer
size. I've tried to keep each set small to make it easy to review in isolation,
but I've also allowed some interrelated ones to get a little bigger than I'd
normally like. I've not done the customary documentation of the expected
checkpatch.pl output because it is large, and because I wanted to get review
of the other parts rolling to get this project unstuck. Future versions of the
patch will document the expected output.
In addition, I noticed a number of places where I could modernize to make the
code match things like linux-user better. I've resisted the urge to do these at
this time, since it would complicate merging the other ~30k lines of diff that
remains after this batch. Future batches should generally be smaller once this
one has landed since they are, by and large, either a bunch of new files to
support armv7, aarch64, riscv64, mips, mipsel, mips64, ppc, ppc64 and ppc64le,
or are adding system calls, which can be done individually or small groups. I've
removed sparc and sparc64 support as they've been removed from FreeBSD and
have been near totally busted for years.
Stacey Son did the bulk of this work originally, but since I had to move things
around so much and/or retool that work in non-trivial ways, I've kept myself as
author, and added his signed-off-by line. I'm unsure of the qemu standard
practice for this, but am happy to learn if this is too far outside its current
mainstream. For a while Sean Bruno did the merges from upstream, and he's
credited using his signed-off-by in appropriate places, though for this patch
set there's only a few. I've tried to ensure that others who have work in
individual patches that I've aggregated together also are reflected in their
signed-off-by. Given the chaotic stat of the upstream repo for its early
history, this may be the best that can be reconstructed at this late date. Most
of these files are 'foundational' so have existed from the earliest days when
record keeping wasn't quite what I'd wish for in hindsight. There was only
really one change that I could easily cherry-pick (Colin's), so I did that.

to cope with historical quirks. Simply the code as a result.

bsd-user: implement path searching
Use the PATH to find the executable given a bare argument. We need to do
this so we can implement mixing native and emulated binaries (e.g.,
execing a x86 native binary from an emulated arm binary to optimize
parts of the build). By finding the binary, we will know how to exec it.

bsd-user: Fix calculation of size to allocate
It was incorrect to subtract off the size of an unsigned int here. In
bsd-user fork, this change was made when moving the arch specific items
to specific files. The size in BSD that's available for the arguments
does not need a return address subtracted from it.

bsd-user: pass the bsd_param into loader_exec
Pass the bsd_param into loader_exec, and adjust. We use it to track the
inital stack allocation and to set stack, open files, and other state
shared between bsdload.c and elfload.c

bsd-user: move arch specific defines out of elfload.c
Move the architecture specific defines to target_arch_elf.h and delete

Add the copyright/license comments, and guard ifdefs.
