Marc-André Lureau 7253dda517 build-sys: drop -Winline when optimization=g
The warning is triggered when compiling with various build options, such
as -Doptimization=g.

From gcc(1) man page about -Winline:
seemingly insignificant changes in the source program can cause the warnings produced by -Winline to appear or disappear.

Such flaky behaviour is best left to the user discretion.

Daniel P. Berrangé acf2f9e1ef src: add new target for regenerating protocol structs files
Introduce a new ninja target

   ninja -C build regen-{PROTO}

eg

   ninja -C build regen-admin_protocol

that will re-create the reference output file based on what the
current pdwtags command emits. A small change is made to squash
whitespace on enum declarations so that introducing a new longer
enum name doesn't trigger re-indent of all existing enum names.

Kirill Shchetiniuk fc201e0fcc ch: Fix refcounting in virCHEventHandlerLoop() and virCHStartEventHandler()
When event handler thread is created inside of
virCHStartEventHandler() the monitor object is refed because the thread
(virCHEventHandlerLoop()) that's created in the very next step
uses it. But right after that, the monitor object is unrefed,
which is wrong because it takes away the reference which was
handed over to the thread. The monitor must be unrefed inside the
thread, when no longer needed.

And while at it, move the unref call of the domain object after
the debug print which obviously accesses the domain definition.

Kirill Shchetiniuk 1db1244752 ch: preserve last error in virCHProcessStop()
If starting a CH domain fails an error is reported and
virCHProcessStart() calls virCHProcessStop() to clean up any
residues. Problem is, inside of virCHProcessStop() some public
APIs might be called (e.g. virNetworkLookupByName(),
virNetworkPortLookupByUUID() and/or virNetworkPortDelete()). Per
our design, public APIs reset last error which means the useful
error reported earlier is lost.

Fix this by calling virErrorPreserveLast() + virErrorRestore()
combo inside of virCHProcessStop().

Daniel P. Berrangé 01a7e84be9 docs: remove references to removed APIs
The glib adoption docs was suggesting avoidance of certain APIs that
were obsoleted by glib, during the transition period. Now that the
referenced APIs no longer exist in libvirt code, they can also be
removed from the docs.

NB, the virStringListRemoveDuplicates method remains since there is
no glib equivalent.

Most, but not all, files in scripts have execute permission. While we
don't need this in order to launch them via meson/ninja build rules,
it is nice to direct execution if they have execution permission. This

Daniel P. Berrangé 40c0c9c838 docs: document workaround for DMARC countermeasures
If a contributor's email domain has a DMARC policy of 'p=quarantine'
or 'p=reject', mailman will apply DMARC countermeasures on all mails
sent to lists.libvirt.org rewriting the "From" header to remove the
sender's email address. e.g.

  From: Your Name via <lists.libvirt.org>

If these countermeasures were not applied, affected mail would either
have gone directly to SPAM, or have been entirely rejected. Mailman3
is unable to be configured to guarantee no mangling of the mail body
so these countermeasures are unavoidable for lists.libvirt.org.

Amongst the various downsides, the From address rewriting has the
bad effect of mangling git commit author attribution.

To avoid this it is required to add two additional git config
settings:

  $ git config --global format.from "Your Name <your@email.com>"
  $ git config --global format.forceInBodyFrom true

Note, *both* are required, even if your ``format.from`` matches
your existing git identity, because the latter only takes effect
once the former is set.

Laine Stump 4c979edaa5 conf: parse interface/source/@dev for all interface types (with backend type='passt')
The original implementation of the passt backend for vhost-user
interfaces erroneously forgot to parse:

  <source dev='blah'/>

for interface type='vhostuser', so it wasn't being added to the passt
commandline, and also wasn't being saved to the domain config. Now we
parse it whenever the <backend> type='passt', no matter what the
interface type, and then throw an error during validation if
source/@dev was specified for interface type = 'user|vhostuser' and
backend type != 'passt'.

Michal Privoznik 1b25f1e53b ch: Don't leak virCHDomainObjPrivate struct members
There are some members of the virCHDomainObjPrivate struct that
are allocated at various stages of domain lifecycle but then are
never freed:

1) cgroup - allocated in virDomainCgroupSetupCgroup()
2) autoCpuset - this one is actually never allocated (and thus is
                always NULL, but soon it may be used. Just free
                it for now, which is a NOP anyways.
3) autoNodeset - same story as 2).

There are two more members, which shouldn't be freed:

1) driver - this is just a raw pointer to the CH driver (see
   virCHDomainObjPrivateAlloc()).

2) monitor - this member is cleared in virCHProcessStop(), way
             before control even gets to
             virCHDomainObjPrivateFree().

Peter Krempa f46e2bf3b0 util: Drop 'virQEMUBuildCommandLineJSONArrayBitmap'
It was used to convert JSON arrays in legacy -object commandline
conversion. Since we now exclusively use JSON with -object, this
infrastructure is no longer needed.

Peter Krempa af227c6ab0 qemu: monitor: Drop support for extra wrapper for 'object_add'
The QAPIfication of objects removed the extra wrapper object which we
were adding in the monitor code to simplify the other callers.

Now that we support only qemus which don't require this we can drop the
support code.

Peter Krempa 51f7b35612 qemuBuildObjectCommandlineFromJSON: Assume all qemus support QEMU_CAPS_OBJECT_JSON
'-object' was qapified (meaning it supports JSON props) in qemu-6.0,
thus now that we require qemu-6.2 we can drop the compatibility code.

Peter Krempa 57cbe6a569 qemuBuildCompatDeprecatedCommandLine: Assume that QEMU_CAPS_COMPAT_DEPRECATED is supported
Bumping minimum version of qemu to 6.2 means that the '-compat' option
is now always supported.

As we were unable to detect it in any other way we based this capability
on QEMU_CAPS_OBJECT_JSON.

Add an example for the automatic/round-robin mapping of iothreads which
users should preferrably use. Until now the example contained even the
full mapping which could push users to use that instead.

Mention that the queues are then automatically distributed among the
iothreads.

Also clarify the need to set 'queues' when mapping threads explicitly
and how the queues are identified.
