An upcoming patch will alter how simple unions, like SocketAddress,
are laid out, which will impact all lines of the form 'addr->u.XXX'
(expanding it to the longer 'addr->u.XXX.data'). For better
legibility in that patch, and less need for line wrapping, it's better
to use a temporary variable to reduce the effect of a layout change to
just the variable initializations, rather than every reference within
a SocketAddress. Also, take advantage of some C99 initialization where
it makes sense (simplifying g_new0() to g_new()).

Just go always through the err label. (Noticed because Coverity
complains that peer is always non-NULL in the error cleanup code,
but removing the "if" is arguably more prone to introducing the
opposite bug in the future).

JSON uses "name":value, but many of our visitor interfaces were
called with visit_type_FOO(v, &value, name, errp). This can be
a bit confusing to have to mentally swap the parameter order to
match JSON order. It's particularly bad for visit_start_struct(),
where the 'name' parameter is smack in the middle of the
otherwise-related group of 'obj, kind, size' parameters! It's
time to do a global swap of the parameter ordering, so that the
'name' parameter is always immediately after the Visitor argument.
Additional reason in favor of the swap: the existing include/qjson.h
prefers listing 'name' first in json_prop_*(), and I have plans to
unify that file with the qapi visitors; listing 'name' first in
qapi will minimize churn to the (admittedly few) qjson.h clients.
Later patches will then fix docs, object.h, visitor-impl.h, and
those clients to match.
Done by first patching scripts/qapi*.py by hand to make generated
files do what I want, then by running the following Coccinelle
script to affect the rest of the code base:
$ spatch --sp-file script `git grep -l '\bvisit_' -- '**/*.[ch]'`
I then had to apply some touchups (Coccinelle insisted on TAB
indentation in visitor.h, and botched the signature of
visit_type_enum() by rewriting 'const char *const strings[]' to
the syntactically invalid 'const char*const[] strings'). The
movement of parameters is sufficient to provoke compiler errors
if any callers were missed.

The socket_dgram method accepts a QAPI SocketAddress object
which it then turns into QemuOpts before calling the
inet_dgram_opts helper method. By converting the latter to
use QAPI SocketAddress directly, the QemuOpts conversion
step can be eliminated.
This removes the very last use of QemuOpts from the
sockets code, so the socket_optslist[] array is also
removed.

Implement a QIOChannel subclass that supports sockets I/O.
The implementation is able to manage a single socket file
descriptor, whether a TCP/UNIX listener, TCP/UNIX connection,
or a UDP datagram. It provides APIs which can listen and
connect either asynchronously or synchronously. Since there
is no asynchronous DNS lookup API available, it uses the
QIOTask helper for spawning a background thread to ensure
non-blocking operation.

Using access() is a time-of-check/time-of-use race condition. It is
okay to use them to provide better error messages, but that is pretty
much it.
This is not one such case; on the other hand, access() *will* skip
unlink() for a non-existent path, so ignore ENOENT return values from
the unlink() system call.

We have two issues with our qapi union layout:
1) Even though the QMP wire format spells the tag 'type', the
C code spells it 'kind', requiring some hacks in the generator.
2) The C struct uses an anonymous union, which places all tag
values in the same namespace as all non-variant members. This
leads to spurious collisions if a tag value matches a non-variant
member's name.
Make the conversion to the new layout for socket-related code.

The QemuOpts-based code treats "option not set" and "option set
to false" the same way for the ipv4 and ipv6 options, because it
is meant to handle only the ",ipv4" and ",ipv6" substrings in
hand-crafted option parsers.
When converting InetSocketAddress to QemuOpts, however, it is
necessary to handle all three cases (not set, set to true, set
to false). Currently we are not handling all cases correctly.
The rules are:
* if none or both options are absent, leave things as is
* if the single present option is Y, the other should be N.
This can be implemented by leaving things as is, or by setting
the other option to N as done in this patch.
* if the single present option is N, the other should be Y.
This is handled by the "else if" branch of this patch.
This ensures that the ipv4 option has an effect on Windows,
where creating the socket with PF_UNSPEC makes an ipv6
socket. With this patch, ",ipv4" will result in a PF_INET
socket instead.

*) Do not use AI_ADDRCONFIG on listening sockets, because this flag
makes it impossible to explicitly listen on '127.0.0.1' if no global
ipv4 address is configured additionally, making this a very
uncomfortable option.
*) Add AI_V4MAPPED hint for connecting sockets.
If your system is globally only connected via ipv6 you often still want
to be able to use '127.0.0.1' and 'localhost' (even if localhost doesn't
also have an ipv6 entry).
For example, PVE - unless explicitly asking for insecure mode - uses
ipv4 loopback addresses with QEMU for live migrations tunneled over SSH.
These fail to start because AI_ADDRCONFIG makes getaddrinfo refuse to
work with '127.0.0.1'.
As for the AI_V4MAPPED flag: glibc uses it by default, and providing
non-0 flags removes it. I think it makes sense to use it.
I also want to point out that glibc explicitly sidesteps POSIX standards
when passing 0 as hints by then assuming both AI_V4MAPPED and
AI_ADDRCONFIG (the latter being a rather weird choice IMO), while
according to POSIX.1-2001 it should be assumed 0. (glibc considers its
choice an improvement.)
Since either AI_CANONNAME or AI_PASSIVE are passed in our cases, glibc's
default flags in turn are disabled again unless explicitly added, which
I do with this patch.

The 'socket_optslist' structure does not contain the 'localaddr' and
'localport' options that are parsed in case you are creating a
'connect' type UDP character device.
I've noticed it happening after commit f43e47dbf6de24db20ec9b588bb6cc762
made qemu abort() after seeing the invalid option.
A minimal reproducer for the case is:
$ qemu-system-x86_64 -chardev udp,id=charrng0,host=127.0.0.1,port=1234,localaddr=,localport=1234
qemu-system-x86_64: -chardev udp,id=charrng0,host=127.0.0.1,port=1234,localaddr=,localport=1234: Invalid parameter 'localaddr'
Aborted (core dumped)
Prior to the commit mentioned above the error would be printed but the
value for localaddr and localport was simply ignored. I did not go
through the code to find out when it was broken.
Add the two fields so that the options can again be parsed correctly and
qemu doesn't abort().

Currently you can specify whether you want a UDP chardev backend
to be IPv4 or IPv6 using the ipv4 or ipv6 options if you use the
QemuOpts parsing code in inet_dgram_opts(). However the QMP struct
parsing code in socket_dgram() doesn't provide this flexibility
(which in turn prevents us from converting the UDP backend handling
to the new style QAPI framework).
Use the existing inet_addr_to_opts() function to convert the
remote->inet address to option strings; this handles ipv4 and
ipv6 flags as well as host and port. (It will also convert any
'to' specification, which is harmless as it is ignored in this
context.)

This is a boiler-plate _nofail variant of qemu_opts_create. Remove and
use error_abort in call sites.
null/0 arguments needs to be added for the id and fail_if_exists fields
in affected callsites due to argument inconsistency between the normal and
no_fail variants.

SO_REUSEADDR should be avoided on Windows but is desired on other operating
systems. So instead of setting it we call socket_set_fast_reuse that will result
in the appropriate behaviour on all operating systems.

socket_connect() sets non-blocking on TCP or UNIX domain sockets if a
callback function is passed. Do the same for file descriptor passing,
otherwise we could unexpectedly be using a blocking file descriptor.

The NBD block supports an URL syntax, for which a URL parser returns
separate hostname and port fields. It also supports the traditional qemu
syntax encoded in a filename. Until now, after parsing the URL to get
each piece of information, a new string is built to be fed to socket
functions.
Instead of building a string in the URL case that is immediately parsed
again, parse the string in both cases and use the QemuOpts interface to
qemu-sockets.c.

Right now the inet connect code tries all available addresses but until one
doesn't fail. It passes local_err each time without clearing it from the
previous failure. This can trigger an assert since the inet connect code
tries to set an error on an object != NULL.
