tox is already testing the most recent versions. Let's use pipenv to
test the oldest versions we claim to support. This matches the stylistic
choice to have pipenv always test our oldest supported Python version, 3.6.
The effect of this is that the python-check-pipenv CI job on gitlab will
now test against much older versions of these linters, which will help
highlight incompatible changes that might otherwise go unnoticed.
Update instructions for adding and bumping versions in setup.cfg. The
reason for deleting the line that gets added to Pipfile is largely just
to avoid having the version minimums specified in multiple places in
config checked into the tree.
(This patch was written by deleting Pipfile and Pipfile.lock, then
explicitly installing each dependency manually at a specific
version. Then, I restored the prior Pipfile and re-ran `pipenv lock
--dev --keep-outdated` to re-add the qemu dependency back to the pipenv
environment while keeping the "old" packages. It's annoying, yes, but I
think the improvement to test coverage is worthwhile.)

These suppressions only apply to a small handful of places. Instead of
disabling them globally, disable them just in the cases where we
need. The design of the machine class grew quite organically with tons
of constructor and class instance variables -- there's little chance of
meaningfully refactoring it in the near term, so just suppress the
warnings for that class.

https://www.python.org/dev/peps/pep-0561/#specification
Create 'py.typed' files in each subpackage that indicate to mypy that
this is a typed module, so that users of any of these packages can use
mypy to check their code as well.
Note: Theoretically it's possible to ditch MANIFEST.in in favor of using
package_data in setup.cfg, but I genuinely could not figure out how to
get it to include things from the *source root* into the *package root*;
only how to include things from each subpackage. I tried!

Pylint updated to 2.9.0 upstream, adding new warnings for things that
re-use the 'err' variable. Luckily, this only breaks the
python-check-tox job, which is allowed to fail as a warning.

Previously the store-conditional code was writing to hex_pred[prednum].
Then, the fGEN_TCG override was reading from there to the destination
variable so that the packet commit logic would handle it properly.
The correct implementation is to write to the destination variable
and don't have the extra read in the override.
Remove the unused arguments from gen_store_conditional[48]

- Move initialization of the ISA bus from typhoon_init() to clipper_init();
this apsect of device topology is really associated with the individual
model, not the core logic chipset. typhoon_init() now returns the IRQ
to use for the output of the ISA PIC.
- In clipper_init(), instantiate an i82378 instance, and connect its
PIC output to the ISA IRQ input provided by typhoon_init(). Remove
the explicit instantiations of i8254 and i82374, as these devices
are subsumed by the i82378.

Since we are emulating a Clipper device topology, we need to set the
minimum PCI device ID to 1, as there is no IRQ mapping for a device
at ID 0 (see sys_dp264.c:clipper_map_irq()).
- Add a 'devfn_min' argument to typhoon_init(). Pass that argument
along to pci_register_root_bus().
- In clipper_init(), pass PCI_DEVFN(1, 0) as the minimum PCI device
ID/function.

Group various structures fields, to better understand what we need to
protect with a lock and what doesn't need it.
Then, add a CoMutex to protect concurrent access of block-copy
data structures. This mutex also protects .copy_bitmap, because its thread-safe
API does not prevent it from assigning two tasks to the same
bitmap region.
Exceptions to the lock:
- .sleep_state is handled in the series "coroutine: new sleep/wake API"
and thus here left as TODO.
- .finished, .cancelled and reads to .ret and .error_is_read will be
protected in the following patch, because are used also outside
coroutines.
- .skip_unallocated is atomic. Including it under the mutex would
increase the critical sections and make them also much more complex.
We can have it as atomic since it is only written from outside and
read by block-copy coroutines.

Moving this function in task_end ensures to update the progress
anyways, even if there is an error.
It also helps in next patch, allowing task_end to have only
one critical section.

Put the logic to determine the copy size in a separate function, so
that there is a simple state machine for the possible methods of
copying data from one BlockDriverState to the other.
Use .method instead of .copy_range as in-out argument, and
include also .zeroes as an additional copy method.
While at it, store the common computation of block_copy_max_transfer
into a new field of BlockCopyState, and make sure that we always
obey max_transfer; that's more efficient even for the
COPY_RANGE_READ_WRITE case.

Use a local variable instead of referencing BlockCopyState through a
BlockCopyCallState or BlockCopyTask every time.
This is in preparation for next patches.
No functional change intended.

co-shared-resource is currently not thread-safe, as also reported
in co-shared-resource.h. Add a QemuMutex because co_try_get_from_shres
can also be invoked from non-coroutine context.

Progressmeter is protected by the AioContext mutex, which
is taken by the block jobs and their caller (like blockdev).
We would like to remove the dependency of block layer code on the
AioContext mutex, since most drivers and the core I/O code are already
not relying on it.
Create a new C file to implement the ProgressMeter API, but keep the
struct as public, to avoid forcing allocation on the heap.
Also add a mutex to be able to provide an accurate snapshot of the
progress values to the caller.

Both users of RateLimit, block-copy.c and blockjob.c, treat
a speed of zero as unlimited, while RateLimit treats it as
"as slow as possible". The latter is nicer from the code
point of view but pretty useless, so disable rate limiting
if a speed of zero is provided.

This is a quality of life helper for plugins so they don't need to
re-implement symbol lookup when dumping an address. The strings are
constant so don't need to be duplicated. One minor tweak is to return
NULL instead of a zero length string to show lookup failed.

Without a single top-level header in the .rst file, the index ended
up linking to all of the top-level headers separately. Now the index
links to the top-level header at the beginning of the document and
any inner headers are correctly linked as sub-items in the index.
