A handful of QAPI doc comments include lines like
"ppcemb: dropped in 3.1". The doc comment parser will just
put these into whatever the preceding section was; sometimes
that's "Notes", and sometimes it's some random other section,
as with "NetClientDriver" where the "'dump': dropped in 2.12"
line ends up in the "Since:" section.
This tends to render wrongly, more so in the upcoming rST
generator, but sometimes even in the Texinfo, as in the case
of QKeyCode:
ac_bookmarks
since 2.10 altgr, altgr_r: dropped in 2.10
Since commit 3264ffced3 (v4.2.0), we have a better place to tell
users about deprecated and deleted functionality --
qemu-deprecated.texi. These "dropped in" remarks all predate it, and
other feature drops of that vintage are not documented anywhere, so
moving these to qemu-deprecated.texi makes little sense. Drop them
instead.

The current doc generation doesn't care much about indentation levels,
but we would like to switch to an rST format, and rST does care about
indentation.
Make the doc comments more strongly consistent about indentation
for multiline constructs like:
@arg: description line 1
description line 2
Returns: line one
line 2
so that there is always exactly one space after the colon, and
subsequent lines align with the first.
This commit is a purely whitespace change, and it does not alter the
generated .texi files (because the texi generation code strips away
all the extra whitespace). This does mean that we end up with some
over-length lines.
Note that when the documentation for an argument fits on a single
line like this:
@arg: one line only
then stray extra spaces after the ':' don't affect the rST output, so
I have not attempted to methodically fix them, though the preference
is a single space here too.

When a command's 'data' is an object, its doc comment describes the
arguments defined there. When 'data' names a type, the doc comment
does not describe arguments. Instead, the doc generator inserts a
pointer to the named type.
An event's doc comment works the same.
We don't actually check doc comments for commands and events.
Instead, QAPISchema._def_command() forwards the doc comment to the
implicit argument type, where it gets checked. Works because the
check only cares for the implicit argument type's members.
Not only is this needlessly hard to understand, it actually falls
apart in two cases:
* When 'data' is empty, there is nothing to forward to, and the doc
comment remains unchecked. Demonstrated by test doc-bad-event-arg.
* When 'data' names a type, we can't forward, as the type has its own
doc comment. The command or event's doc comment remains unchecked.
Demonstrated by test doc-bad-boxed-command-arg.
The forwarding goes back to commit 069fb5b250 "qapi: Prepare for
requiring more complete documentation", put to use in commit
816a57cd6e "qapi: Fix detection of bogus member documentation". That
fix was incomplete.
To fix this, make QAPISchemaCommand and QAPISchemaEvent check doc
comments, and drop the forwarding of doc comments to implicit argument
types.

Previously there was a single instance of the timer used by
monitor triggered announces, that's OK, but when combined with the
previous change that lets you have announces for subsets of interfaces
it's a bit restrictive if you want to do different things to different
interfaces.
Add an 'id' field to the announce, and maintain a list of the
timers based on id.
This allows you to for example:
a) Start an announce going on interface eth0 for a long time
b) Start an announce going on interface eth1 for a long time
c) Kill the announce on eth0 while leaving eth1 going.

Allow the caller to restrict the set of interfaces that announces are
sent on. The default is still to send on all interfaces.
e.g.
{ "execute": "announce-self", "arguments": { "initial": 50, "max": 550, "rounds": 5, "step": 50, "interfaces": ["vn2", "vn1"] } }
This doesn't affect the behaviour of migraiton announcments.
Note: There's still only one timer for the qmp command, so that
performing an 'announce-self' on one list of interfaces followed
by another 'announce-self' on another list will stop the announces
on the existing set.

Add a qmp command that can trigger guest announcements.
It uses its own announce-timer instance, and parameters
passed to it explicitly in the command.
Like most qmp commands, it's in the main thread/bql, so
there's no racing with any outstanding timer.

It's been marked as deprecated since QEMU v2.9.0, so that should have
been enough time for everybody to either just drop unnecessary "vlan=0"
parameters, to switch to the modern -device + -netdev syntax for connecting
guest NICs with host network backends, or to switch to the "hubport" netdev
in case hubs are really wanted instead.

"-net dump" has been marked as deprecated since QEMU v2.10, since it
only works with the deprecated 'vlan' parameter (or hubs). Network
dumping should be done with "-object filter-dump" nowadays instead.
Since nobody complained so far about the deprecation message, let's
finally get rid of "-net dump" now.

QEMU can emulate hubs to connect NICs and netdevs. This is currently
primarily used for the mis-named 'vlan' feature of the networking
subsystem. Now the 'vlan' feature has been marked as deprecated, since
its name is rather confusing and the users often rather mis-configure
their network when trying to use it. But while the 'vlan' parameter
should be removed at one point in time, the basic idea of emulating
a hub in QEMU is still good: It's useful for bundling up the output of
multiple NICs into one single l2tp netdev for example.
Now to be able to use the hubport feature without 'vlan's, there is one
missing piece: The possibility to connect a hubport to a netdev, too.
This patch adds this possibility by introducing a new "netdev=..."
parameter to the hubports.
To bundle up the output of multiple NICs into one socket netdev, you can
now run QEMU with these parameters for example:
qemu-system-ppc64 ... -netdev socket,id=s1,connect=:11122 \
-netdev hubport,hubid=1,id=h1,netdev=s1 \
-netdev hubport,hubid=1,id=h2 -device e1000,netdev=h2 \
-netdev hubport,hubid=1,id=h3 -device virtio-net-pci,netdev=h3
For using the socket netdev, you have got to start another QEMU as the
receiving side first, for example with network dumping enabled:
qemu-system-x86_64 -M isapc -netdev socket,id=s0,listen=:11122 \
-device ne2k_isa,netdev=s0 \
-object filter-dump,id=f1,netdev=s0,file=/tmp/dump.dat
After the ppc64 guest tried to boot from both NICs, you can see in the
dump file (using Wireshark, for example), that the output of both NICs
(the e1000 and the virtio-net-pci) has been successfully transfered
via the socket netdev in this case.
