is only "current" if under the BQL.

5f50be9b58 async: the main AioContext is only "current" if under the BQL
If we want to wake up a coroutine from a worker thread, aio_co_wake()
currently does not work.  In that scenario, aio_co_wake() calls
aio_co_enter(), but there is no current AioContext and therefore
qemu_get_current_aio_context() returns the main thread.  aio_co_wake()
then attempts to call aio_context_acquire() instead of going through
aio_co_schedule().

The default case of qemu_get_current_aio_context() was added to cover
synchronous I/O started from the vCPU thread, but the main and vCPU
threads are quite different.  The main thread is an I/O thread itself,
only running a more complicated event loop; the vCPU thread instead
is essentially a worker thread that occasionally calls
qemu_mutex_lock_iothread().  It is only in those critical sections
that it acts as if it were the home thread of the main AioContext.

Therefore, this patch detaches qemu_get_current_aio_context() from
iothreads, which is a useless complication.  The AioContext pointer
is stored directly in the thread-local variable, including for the
main loop.  Worker threads (including vCPU threads) optionally behave
as temporary home threads if they have taken the big QEMU lock,
but if that is not the case they will always schedule coroutines
on remote threads via aio_co_schedule().

With this change, the stub qemu_mutex_iothread_locked() must be changed
from true to false.  The previous value of true was needed because the
main thread did not have an AioContext in the thread-local variable,
but now it does have one.

a2cd86a94a hw/audio/sb16: Avoid assertion by restricting I/O sampling rate range
While the SB16 seems to work up to 48000 Hz, the "Sound Blaster Series
Hardware Programming Guide" limit the sampling range from 4000 Hz to
44100 Hz (Section 3-9, 3-10: Digitized Sound I/O Programming, tables
3-2 and 3-3).

Later, section 6-15 (DSP Commands) is more specific regarding the 41h /
42h registers (Set digitized sound output sampling rate):

  Valid sampling rates range from 5000 to 45000 Hz inclusive.

There is no comment regarding error handling if the register is filled
with an out-of-range value.  (See also section 3-28 "8-bit or 16-bit
Auto-initialize Transfer"). Assume limits are enforced in hardware.

This fixes triggering an assertion in audio_calloc():

31fa83bd2b tests/tcg/configure.sh: tweak quoting of target_compiler
If you configure the host compiler with a multi-command stanza like:

  --cc="ccache gcc"

then the configure.sh machinery falls over with confusion. Work around
this by ensuring we correctly quote so where we need a complete
evaluation we get it. Of course the has() check needs single variable
so we need to unquote that. This does mean it essentially checks that
just the ccache command exits but if we got past that step we still
check the compiler actually does something.

30ebb9aa92 block: improve permission conflict error message
Now permissions are updated as follows:
 1. do graph modifications ignoring permissions
 2. do permission update

 (of course, we rollback [1] if [2] fails)

So, on stage [2] we can't say which users are "old" and which are
"new" and exist only since [1]. And current error message is a bit
outdated. Let's improve it, to make everything clean.

While being here, add also a comment and some good assertions.

iotests 283, 307, qsd-jobs outputs are updated.

2c0a3acb95 block: improve bdrv_child_get_parent_desc()
We have different types of parents: block nodes, block backends and
jobs. So, it makes sense to specify type together with name.

Next, this handler us used to compose an error message about permission
conflict. And permission conflict occurs in a specific place of block
graph. We shouldn't report name of parent device (as it refers another
place in block graph), but exactly and only the name of the node. So,
use bdrv_get_node_name() directly.

iotest 283 output is updated.

6b9c277797 gitlab: add python linters to CI
Add a Python container that has just enough juice for us to run the
Python code quality analysis tools. Base this container on Fedora,
because Fedora has very convenient packaging for testing multiple Python
versions.

We need python3, pip (for pulling packages), pipenv and virtualenv for
creating virtual environments, and tox for running tests. make is needed
for running 'make check-tox' and 'make venv-check' targets. Python3.10
is needed explicitly because the tox package only pulls in 3.6-3.9, but
we wish to test the forthcoming release of Python as well to help
predict any problems. Lastly, we need gcc to compile PyPI packages that
may not have a binary distribution available.

Add two tests:

check-python-pipenv uses pipenv to test a frozen, very explicit set of
packages against our minimum supported python version, Python 3.6. This
test is not allowed to fail. The dependencies this test uses do not
change unless python/Pipfile.lock is changed.

check-python-tox uses tox to install the latest versions of required
python dependencies against a wide array of Python versions from 3.6 to
3.9, even including the yet-to-be-released Python 3.10. This test is
allowed to fail with a warning.

beb6b57b3b python: create qemu packages
move python/qemu/*.py to python/qemu/[machine, qmp, utils]/*.py and
update import directives across the tree.

This is done to create a PEP420 namespace package, in which we may
create subpackages. To do this, the namespace directory ("qemu") should
not have any modules in it. Those files will go into new 'machine',
'qmp' and 'utils' subpackages instead.

Implement machine/__init__.py making the top-level classes and functions
from its various modules available directly inside the package. Change
qmp.py to qmp/__init__.py similarly, such that all of the useful QMP
library classes are available directly from "qemu.qmp" instead of
"qemu.qmp.qmp".

A property has been added to allow users to access it without using
private attributes, and with that, the directory is created on first

583e6a5f55 target/xtensa: clean up unaligned access
Xtensa cores may or may not have hardware support for unaligned memory
access. Remove TARGET_ALIGNED_ONLY=y from all xtensa configurations and
pass MO_ALIGN in memory access flags for all operations that would raise
an exception.
Simplify use of gen_load_store_alignment by passing access size and
alignment requirements in single parameter.
Drop condition from xtensa_cpu_do_unaligned_access and replace it with
assertion.
Add a test.
