Change the ppc440_sdram model to a QOM class derived from the
PPC4xx-dcr-device and name it ppc4xx-sdram-ddr2. This is mostly
modelling the DDR2 SDRAM controller found in the 460EX (used on the
sam460ex board). Newer SoCs (regardless of their PPC core, e.g. 405EX)
may have this controller but we only emulate enough of it for the
sam460ex u-boot firmware.

Change the ppc4xx_sdram model to a QOM class derived from the

modelling the DDR SDRAM controller found in the 440EP (used on the
bamboo board) but also backward compatible with the older DDR
controllers on some 405 SoCs so we also use it for those now. This
likely does not cause problems for guests we run as the new features
are just not accessed but to model 405 SoC accurately some features
may have to be disabled or the model split between 440 and older.
Newer SoCs (regardless of their PPC core, e.g. 405EX) may have an
updated DDR2 SDRAM controller implemented by the ppc440_sdram model
(only partially, enough for the 460EX on the sam460ex) that is not yet
QOM'ified in this patch. That is intended to become ppc4xx-sdram-ddr2
when QOM'ified later.

When running Tock on the OpenTitan machine.

a power of 2. The size was also smaller then TARGET_PAGE_SIZE.
This patch ensures that any TLB size less then TARGET_PAGE_SIZE is

To boot S-mode firmware payload like EDK2 from persistent
flash storage, qemu needs to pass the flash address as the
next_addr in fw_dynamic_info to the opensbi.
When both -kernel and -pflash options are provided in command line,
the kernel (and initrd if -initrd) will be copied to fw_cfg table.
The S-mode FW will load the kernel/initrd from fw_cfg table.
If only pflash is given but not -kernel, then it is the job of
of the S-mode firmware to locate and load the kernel.
In either case, update the kernel_entry with the flash address
so that the opensbi can jump to the entry point of the S-mode
firmware.

Here are the changes:
- drop tests/ from fifo/pipe path, to avoid directory issues
- use g_find_program() to lookup the socat executable (otherwise we
would need to change ChanneCommand to use G_SPAWN_SEARCH_PATH, and deal
with missing socat differently)

The initial implementation was changing the pipe state created by GLib
to PIPE_NOWAIT, but it turns out it doesn't work (read/write returns an
error). Since reading may return less than the requested amount, it
seems to be non-blocking already. However, the IO operation may block
until the FD is ready, I can't find good sources of information, to be
safe we can just poll for readiness before.
Alternatively, we could setup the FDs ourself, and use UNIX sockets on
Windows, which can be used in blocking/non-blocking mode. I haven't
tried it, as I am not sure it is necessary.

Simplify qio_channel_command_new_spawn() with GSpawn API. This will
allow to build for WIN32 in the following patches.
As pointed out by Daniel Berrangé: there is a change in semantics here
too. The current code only touches stdin/stdout/stderr. Any other FDs
which do NOT have O_CLOEXEC set will be inherited. With the new code,
all FDs except stdin/out/err will be explicitly closed, because we don't
set the flag G_SPAWN_LEAVE_DESCRIPTORS_OPEN. The only place we use
QIOChannelCommand today is the migration exec: protocol, and that is
only declared to use stdin/stdout.

The /io/channel/command/echo tests run the reader side and the writer
side with the same underlying command channel. Setting the blocking mode
of the fd/handles while the other end is already reading/writing may
create issues (deadlock in win32 when earlier attempt of this series
were using SetNamedPipeHandleState). Let's just do it before spawning
the threads to avoid further concurrency issues.

According to msdn documentation and Linux man pages, send() should try
to send as much as possible in blocking mode, while recv() may return
earlier with a smaller available amount, we should try to continue
send/recv from there.

With a pipe or other reasons, read/write may return less than the
requested bytes. This happens with the test-io-channel-command test on
Windows. glib spawn code uses a binary pipe of 4096 bytes, and the first
read returns that much (although more are requested), for some unclear
reason...

As described in:
https://learn.microsoft.com/en-us/visualstudio/debugger/how-to-set-a-thread-name-in-native-code?view=vs-2022
SetThreadDescription() is available since Windows 10, version 1607 and
in some versions only by "Run Time Dynamic Linking". Its declaration is
not yet in mingw, so we lookup the function the same way glib does.
Tested with Visual Studio Community 2022 debugger.

The patch adds "show_menubar" command line option for GTK UI similar to
"show_tabs". This option allows to hide menu bar initially, it still can
be toggled by shortcut and other shortcuts still work.
