46f49468c6 qapi/error: Repurpose QAPIError as an abstract base exception class
Rename QAPIError to QAPISourceError, and then create a new QAPIError
class that serves as the basis for all of our other custom exceptions,
without specifying any class properties.

This leaves QAPIError as a package-wide error class that's suitable for
any current or future errors.

(Right now, we don't have any errors that DON'T also want to specify a
Source location, but this MAY change. In these cases, a common abstract
ancestor would be desired.)

Add docstrings to explain the intended function of each error class.

d211556fe3 docs/system/gdb.rst: Document how to debug multicore machines
Document how multicore machines appear to GDB when debugged
via the debug stub. This is particularly non-intuitive for
the "multiple heterogenous clusters" case, but unfortunately
as far as I know there is no way with the remote protocol
for the stub to tell gdb "I have 2 inferiors, please connect
to both", so the user must set it all up manually.

c81cfb89bc docs: Add a QEMU Code of Conduct and Conflict Resolution Policy document
In an ideal world, we would all get along together very well, always be
polite and never end up in huge conflicts. And even if there are conflicts,
we would always handle each other fair and respectfully. Unfortunately,
this is not an ideal world and sometimes people forget how to interact with
each other in a professional and respectful way. Fortunately, this seldom
happens in the QEMU community, but for such rare cases it is preferrable
to have a basic code of conduct document available to show to people
who are misbehaving.  In case that does not help yet, we should also have
a conflict resolution policy ready that can be applied in the worst case.

The Code of Conduct document tries to be short and to the point while
trying to remain friendly and welcoming; it is based on the Fedora Code
of Conduct[1] with extra detail added based on the Contributor Covenant
1.3.0[2].  Other proposals included the Contributor Covenant 1.3.0 itself
or the Django Code of Conduct[3] (which is also a derivative of Fedora's)
but, in any case, there was agreement on keeping the conflict resolution
policy separate from the CoC itself.

An important point is whether to apply the code of conduct to violations
that occur outside public spaces.  The text herein restricts that to
individuals acting as a representative or a member of the project or
its community.  This is intermediate between the Contributor Covenant
(which only mentions representatives of the community, for example using
an official project e-mail address or posting via an official social media
account), and the Django Code of Conduct, which says that violations of
this code outside these spaces "may" be considered but otherwise applies
no limit.

The conflict resolution policy is based on the Drupal Conflict Resolution
Policy[4] and its derivative, the Mozilla Consequence Ladder[5].

Implementing FUSE exports required no changes to the storage daemon, so

561dbb41b1 i386: Make migration fail when Hyper-V reenlightenment was enabled but 'user_tsc_khz' is unset
KVM doesn't fully support Hyper-V reenlightenment notifications on
migration. In particular, it doesn't support emulating TSC frequency
of the source host by trapping all TSC accesses so unless TSC scaling
is supported on the destination host and KVM_SET_TSC_KHZ succeeds, it
is unsafe to proceed with migration.

KVM_SET_TSC_KHZ is called from two sites: kvm_arch_init_vcpu() and
kvm_arch_put_registers(). The later (intentionally) doesn't propagate
errors allowing migrations to succeed even when TSC scaling is not
supported on the destination. This doesn't suit 're-enlightenment'
use-case as we have to guarantee that TSC frequency stays constant.

Require 'tsc-frequency=' command line option to be specified for successful
migration when re-enlightenment was enabled by the guest.

QAPI doesn't know the aliases 'tty' and 'parport' and there is no
reason to prefer them to the real names of the backends 'serial' and
'parallel'.

Since warnings are not allowed in 'make check' output, we can't test
the deprecated alias any more. Remove it from test-char.

99b1e64688 qemu-img: Use user_creatable_process_cmdline() for --object
This switches qemu-img from a QemuOpts-based parser for --object to
user_creatable_process_cmdline() which uses a keyval parser and enforces
the QAPI schema.

Apart from being a cleanup, this makes non-scalar properties accessible.

As a side effect, fix wrong exit codes in the object parsing error path
of 'qemu-img compare'. This was broken in commit 334c43e2c3 because
&error_fatal exits with an exit code of 1, while it should have been 2.

Document that exit code 0 is also returned when just requested help was
printed instead of comparing images. This is preexisting behaviour that
isn't changed by this patch, though another instance of it is added with
'--object help'.

39c4c27d37 qapi/qom: Add ObjectOptions for secret*, deprecate 'loaded'
This adds a QAPI schema for the properties of the secret* objects.

The 'loaded' property doesn't seem to make sense as an external
interface: It is automatically set to true in ucc->complete, and
explicitly setting it to true earlier just means that additional options
will be silently ignored.

In other words, the 'loaded' property is useless. Mark it as deprecated
in the schema from the start.

This adds a QAPI schema for the properties of the rng-* objects.

The 'opened' property doesn't seem to make sense as an external

explicitly setting it to true earlier just means that trying to set
additional options will result in an error. After the property has once
been set to true (i.e. when the object construction has completed), it
can never be reset to false. In other words, the 'opened' property is
useless. Mark it as deprecated in the schema from the start.

The generic 'migrate_set_parameters' command handle all types of param.

Only the QMP commands were documented in the deprecations page, but the
rationale for deprecating applies equally to HMP, and the replacements
exist. Furthermore the HMP commands are just shims to the QMP commands,
so removing the latter breaks the former unless they get re-implemented.
