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.

Based on commit 1433e38cc8 ("hpet: do not overwrite properties on
post_load"), add the basic migration support to Rust HPET.
The current migration implementation introduces multiple unsafe
callbacks. Before the vmstate builder, one possible cleanup approach is
to wrap callbacks in the vmstate binding using a method similar to the
vmstate_exist_fn macro.
However, this approach would also create a lot of repetitive code (since
vmstate has so many callbacks: pre_load, post_load, pre_save, post_save,
needed and dev_unplug_pending). Although it would be cleaner, it would
somewhat deviate from the path of the vmstate builder.
Therefore, firstly focus on completing the functionality of HPET, and
those current unsafe callbacks can at least clearly indicate the needed
functionality of vmstate. The next step is to consider refactoring
vmstate to move towards the vmstate builder direction.
Additionally, update rust.rst about Rust HPET can support migration.

For change, pause, resume, complete, dismiss and finalize actions
corresponding job- and block-job commands are almost equal. The
difference is in find_block_job_locked() vs find_job_locked()
functions. What's different?
1. find_block_job_locked() checks whether the found job is a block-job.
This is OK when moving to more generic API, no needs to document this
change.
2. find_block_job_locked() reports DeviceNotActive on failure, when
find_job_locked() reports GenericError. So, let's document this
difference in deprecated.txt. Still, for dismiss and finalize errors
are not documented at all, so be silent in deprecated.txt as well.

Python 3.8 went "end of life" in October 2024 and Fedora 42 dropped
this version already, so the "python" CI job is currently failing.
Thus it's time to drop support for this Python version in QEMU, too.
While we're at it, also look for "python3.13" in the configure script.

Liveness needs to track carry-live state in order to
determine if the (hidden) output of the opcode is used.
Code generation needs to track carry-live state in order
to avoid clobbering cpu flags when loading constants.
So far, output routines and backends are unchanged.

Even though bswap64 can only be used with TCG_TYPE_I64,
rename the opcode to maintain uniformity.
