When a command's arguments are specified as an explicit type T,
generated documentation points to the members of T.
Example:
##
# @announce-self:
#
# Trigger generation of broadcast RARP frames to update network
[...]
##
{ 'command': 'announce-self', 'boxed': true,
'data' : 'AnnounceParameters'}
generates
"announce-self" (Command)
-------------------------
Trigger generation of broadcast RARP frames to update network
[...]
Arguments
~~~~~~~~~
The members of "AnnounceParameters"
Except when the command takes its arguments unboxed , i.e. it doesn't
have 'boxed': true, we generate *nothing*. A few commands have a
reference in their doc comment to compensate, but most don't.
Example:
##
# @blockdev-snapshot-sync:
#
# Takes a synchronous snapshot of a block device.
#
# For the arguments, see the documentation of BlockdevSnapshotSync.
[...]
##
{ 'command': 'blockdev-snapshot-sync',
'data': 'BlockdevSnapshotSync',
'allow-preconfig': true }
generates
"blockdev-snapshot-sync" (Command)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Takes a synchronous snapshot of a block device.
For the arguments, see the documentation of BlockdevSnapshotSync.
[...]
Same for event data.
Fix qapidoc.py to generate the reference regardless of boxing. Delete
now redundant references in the doc comments.

Just do me a favor and test build the html docs in the stable branch and verify that they appear to render correctly with a quick visual glance -- we've been poking around a lot in that area.
I don't see any obvious point of conflict in this patch, but I have a nagging doubt.
As long as they build and they look alright, I'm confident it's fine.
