[v7,0/1] util/async-teardown: appear in query-command-line-options

Message

Claudio Imbrenda May 5, 2023, noon UTC

Add new -run-with option with an async-teardown=on|off parameter. It
is visible in the output of query-command-line-options QMP command, so
it can be discovered and used by libvirt.

The option -async-teardown is now redundant, deprecate it.

v6->v7
* move variable declaration inside #ifdef to avoid compile time errors
  on *BSD due to unused variables. [thomas]

v5->v6
* deprecate the old -async-teardown option instead of removing it,
  since it has now appeared in 2 QEMU releases
* use -run-with as a grab bag commandline option for the async-teardown
  boolean parameter [paolo,markus,thomas]

v4->v5
* reword commit message [Markus]
* document the removal of the -async-teardown commandline option in
  docs/about/removed-features.rst [Markus]

v3->v4
* completely remove the useless -async-teardown option, since it was
  not wired up properly and it had no users [thomas]
* QEMU should be always uppercase in text and documentation [thomas]
* if the new -teardown option fails to parse, exit immediately instead
  of returning an error [thomas]

v2->v3
* add a new teardown option with an async parameter [Markus]
* reworded documentation of existing -async-teardown option so that it
  points to the new teardown option

v1->v2
* remove the unneeded .implied_opt_name initializer [Thomas]
