A log_mask_ln!() macro is provided which expects similar arguments as the
C version. However, the formatting works as one would expect from Rust.
To maximize code reuse the macro is just a thin wrapper around
qemu_log(). Also, just the bare minimum of logging masks is provided
which should suffice for the current use case of Rust in QEMU.

Provide an implementation of std::error::Error that bridges the Rust
anyhow::Error and std::panic::Location types with QEMU's Error*.
It also has several utility methods, analogous to error_propagate(),
that convert a Result into a return value + Error** pair. One important
difference is that these propagation methods *panic* if *errp is NULL,
unlike error_propagate() which eats subsequent errors[1]. The reason
for this is that in C you have an error_set*() call at the site where
the error is created, and calls to error_propagate() are relatively rare.
In Rust instead, even though these functions do "propagate" a
qemu_api::Error into a C Error**, there is no error_setg() anywhere that
could check for non-NULL errp and call abort(). error_propagate()'s
behavior of ignoring subsequent errors is generally considered weird,
and there would be a bigger risk of triggering it from Rust code.
[1] This is actually a violation of the preconditions of error_propagate(),
so it should not happen. But you never know...

This restores the linting baseline in qapidoc. The order of some imports
change slightly here due to configuring isort a little better:
previously, isort was having difficulty understanding that "compat" and
"qapidoc_legacy" were local modules because docs/sphinx "isn't a python
package". Configuring this manually, isort chooses a different import
ordering, which _is_ intentional here.
Also: extra ignores are added for pylint. The most recent versions of
pylint don't require these ignores, but the oldest versions we support
do, so in the extra ignores go.

Meson has support for invoking clippy and rustdoc on all crates (1.7.0 for
clippy, 1.8.0 for rustdoc). Use it instead of the homegrown version; this
requires disabling the multiple_crate_versions lint (the only one that was
enabled from the "cargo" group)---which was not particularly useful anyway
because all dependencies are converted by hand into Meson subprojects.
rustfmt is still not supported.

Doctests are weird. They are essentially integration tests, but they're
"ran" by executing rustdoc --test, which takes a compiler-ish
command line. This is supported by Meson 1.8.0.
Because they run the linker and need all the .o files, run them in the
build jobs rather than the test jobs.

libqemuutil is not meant be linked as a whole; if modules are enabled, doing
so results in undefined symbols (corresponding to QMP commands) in
rust/qemu-api/rust-qemu-api-integration.
Support for "objects" in Rust executables is available in Meson 1.8.0; use it
to switching to the same dependencies that C targets use: link_with for
libqemuutil, and objects for everything else.

Both machines were added with little-endian in mind only (the
"endianness" CPU property was hard-wired to "true", see commits
133d23b3ad and a88bbb006a), so the variants that showed up
on the big endian target likely never worked. We deprecated these
non-working machine variants two releases ago, and so far nobody
complained, so it should be fine now to disable them. Hard-wire
the machines to little endian now.

While we model a 16-elements RX FIFO since the PL011 model was
introduced in commit cdbdb648b7 ("ARM Versatile Platform Baseboard
emulation"), we only read 1 char at a time!
Have can_receive() return how many elements are available, and use that
in receive().
This is the Rust version of commit 3e0f118f82 ("hw/char/pl011: Really
use RX FIFO depth"); but it also adds back a comment that is present
in commit f576e0733c ("hw/char/pl011: Add support for loopback") and
absent in the Rust code.

According to QEMU manual:
Older options like `-hda` are essentially macros which expand into
`-drive` options for various drive interfaces. The original forms
bake in a lot of assumptions from the days when QEMU was emulating a
legacy PC, they are not recommended for modern configurations.

As the presence of OpRegion is used to detect IGD device now, and
guest driver usually depends on OpRegion to work. Enable OpRegion
on IGD devices by default for out-of-the-box passthrough experience
(except pre-boot display output), especially for libvirt users.
Example of IGD passthrough with libvirt:
<hostdev mode="subsystem" type="pci" managed="yes">
<source>
<address domain="0x0000" bus="0x00" slot="0x02" function="0x0"/>
</source>
<rom file="/path/to/igd/rom"/>
<address type="pci" domain="0x0000" bus="0x00" slot="0x02" function="0x0"/>

Intel only provides legacy VBIOS for IGD up to Gen9, and there is no
CSM support on later devices. Additionally, Seabios can only handle
32-bit BDSM register used until Gen9. Since legacy mode requires VGA
capability, restrict it to Gen6 through Gen9 devices.

Sphinx requires that labels within documents are unique across the
whole manual. This is because the "create a hyperlink" directive
specifies only the name of the label, not a filename+label. Some
Sphinx versions will warn about duplicate labels, but even if there
is no warning there is still an ambiguity and no guarantee that the
hyperlink will be created to the right target.
For QEMU this is awkward, because we have various .rst.inc fragments
which we include into multiple .rst files. If you define a label in
the .rst.inc file then it will be a duplicate label. We have mostly
worked around this by not putting labels into those .rst.inc files,
or by adding "insert a label" functionality into the hxtool extension
(see commit 1eeb432a95 "doc/sphinx/hxtool.py: add optional label
argument to SRST directive").
Unfortunately in commit 7f6314427e ("docs/devel: add a codebase
section") we accidentally added a duplicate label, because not all
Sphinx versions warn about the mistake.
In this case the link was only from the developer docs codebase
summary, so as the simplest fix for the stable branch, we drop
the link entirely.
