Merge remote-tracking branch 'remotes/qmp-unstable/queue/qmp' into staging
* remotes/qmp-unstable/queue/qmp:
qapi: skip redundant includes
monitor: Add netdev_del id argument completion.
monitor: Add netdev_add type argument completion.
monitor: Add set_link arguments completion.
monitor: Add chardev-add backend argument completion.
monitor: Add chardev-remove command completion.
monitor: Convert sendkey to use command_completion.
qapi: Show qapi-commands.py invocation in qapi-code-gen.txt
qapi: Replace uncommon use of the error API by the common one
tests: Don't call visit_end_struct() after visit_start_struct() fails
hw: Don't call visit_end_struct() after visit_start_struct() fails
hmp: Call visit_end_struct() after visit_start_struct() succeeds
qapi: Un-inline visit of implicit struct
qapi-visit.py: Clean up a sloppy use of field prefix
qapi: Clean up shadowing of parameters and locals in inner scopes
qapi-visit.py: Clean up confusing push_indent() / pop_indent() use
qapi: Replace start_optional()/end_optional() by optional()
qapi: Remove unused Visitor callbacks start_handle(), end_handle()
qapi: Normalize marshalling's visitor initialization and cleanup
