Markus Armbruster ae7ccd50c3 qapi: Fix mangled "Returns" sections in documentation 
Commit e050e42678 (qapi: Use explicit bulleted lists) added list
markup to correct bad rendering:

    A JSON block comment like this:
         Returns: nothing on success
                  If @node is not a valid block device, DeviceNotFound
                  If @name is not found, GenericError with an explanation

    renders like this:

         Returns: nothing on success If node is not a valid block device,
         DeviceNotFound If name is not found, GenericError with an explanation

    because whitespace is not significant.

    Use an actual bulleted list, so that the formatting is correct.

It missed a few instances.  Commit a937b6aa73 (qapi: Reformat doc
comments to conform to current conventions) then reflowed them.

Revert the reflowing, and add list markup.

# = QEMU Object Model (QOM)
##
##
# @ObjectPropertyInfo:
#
# @name: the name of the property
#
# @type: the type of the property. This will typically come in one of
# four forms:
#
# 1) A primitive type such as 'u8', 'u16', 'bool', 'str', or
# 'double'. These types are mapped to the appropriate JSON
# type.
#
# 2) A child type in the form 'child<subtype>' where subtype is a
# qdev device type name. Child properties create the
# composition tree.
#
# 3) A link type in the form 'link<subtype>' where subtype is a
# qdev device type name. Link properties form the device model
# graph.
#
# @description: if specified, the description of the property.
#
# @default-value: the default value, if any (since 5.0)
#
# Since: 1.2
##

##
# @qom-list:
#
# This command will list any properties of a object given a path in
# the object model.
#
# @path: the path within the object model. See @qom-get for a
# description of this parameter.
#
# Returns: a list of @ObjectPropertyInfo that describe the properties
# of the object.
#
# Since: 1.2
#
# Example:
#
# -> { "execute": "qom-list",
# "arguments": { "path": "/chardevs" } }
# <- { "return": [ { "name": "type", "type": "string" },
# { "name": "parallel0", "type": "child<chardev-vc>" },

##
# @qom-get:
#
# This command will get a property from a object model path and return
# the value.
#
# @path: The path within the object model. There are two forms of
# supported paths--absolute and partial paths.
#
# Absolute paths are derived from the root object and can follow
# child<> or link<> properties. Since they can follow link<>
# properties, they can be arbitrarily long. Absolute paths look
# like absolute filenames and are prefixed with a leading slash.
#
# Partial paths look like relative filenames. They do not begin
# with a prefix. The matching rules for partial paths are subtle
# but designed to make specifying objects easy. At each level of
# the composition tree, the partial path is matched as an absolute
# path. The first match is not returned. At least two matches
# are searched for. A successful result is only returned if only
# one match is found. If more than one match is found, a flag is
# return to indicate that the match was ambiguous.
#
# @property: The property name to read
#
# Returns: The property value. The type depends on the property type.
# child<> and link<> properties are returned as #str pathnames.
# All integer property types (u8, u16, etc) are returned as #int.
#
# Since: 1.2
#
# Examples:
#
# 1. Use absolute path
#
# -> { "execute": "qom-get",
# "arguments": { "path": "/machine/unattached/device[0]",
# "property": "hotplugged" } }
# <- { "return": false }
#
# 2. Use partial path

# "arguments": { "path": "unattached/sysbus",
# "property": "type" } }
# <- { "return": "System" }

# @MemoryBackendFileProperties:
#
# Properties for memory-backend-file objects.
#
# @align: the base address alignment when QEMU mmap(2)s @mem-path.
# Some backend stores specified by @mem-path require an alignment
# different than the default one used by QEMU, e.g. the device DAX
# /dev/dax0.0 requires 2M alignment rather than 4K. In such cases,
# users can specify the required alignment via this option. 0
# selects a default alignment (currently the page size).
# (default: 0)
#
# @offset: the offset into the target file that the region starts at.
# You can use this option to back multiple regions with a single
# file. Must be a multiple of the page size.
# (default: 0) (since 8.1)
#
# @discard-data: if true, the file contents can be destroyed when QEMU
# exits, to avoid unnecessarily flushing data to the backing file.
# Note that @discard-data is only an optimization, and QEMU might
# not discard file contents if it aborts unexpectedly or is
# terminated using SIGKILL. (default: false)
#
# @mem-path: the path to either a shared memory or huge page
# filesystem mount
#
# @pmem: specifies whether the backing file specified by @mem-path is
# in host persistent memory that can be accessed using the SNIA
# NVM programming model (e.g. Intel NVDIMM).
#
# @readonly: if true, the backing file is opened read-only; if false,
# it is opened read-write. (default: false)
#
# @rom: whether to create Read Only Memory (ROM) that cannot be modified
# by the VM. Any write attempts to such ROM will be denied. Most
# use cases want writable RAM instead of ROM. However, selected use
# cases, like R/O NVDIMMs, can benefit from ROM. If set to 'on',
# create ROM; if set to 'off', create writable RAM; if set to
# 'auto', the value of the @readonly property is used. This
# property is primarily helpful when we want to have proper RAM in
# configurations that would traditionally create ROM before this
# property was introduced: VM templating, where we want to open a
# file readonly (@readonly set to true) and mark the memory to be
# private for QEMU (@share set to false). For this use case, we need
# writable RAM instead of ROM, and want to set this property to 'off'.

# Features:
#
# @deprecated: Member @opened is deprecated. Setting true doesn't
