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 net-related code.

Move the creation of the dump client from net_dump_init() into
net_init_dump(), so we can later use the former function for
dump via netfilter, too. Also rename net_dump_init() to
net_dump_state_init() to make it easier distinguishable from
net_init_dump().

muldiv64() is used to convert nanoseconds to microseconds.
x = muldiv64(qemu_clock_get_ns(..), 1000000, get_ticks_per_sec());

When -net dump fails, it first reports a specific error, then a
generic one, like this:
$ qemu-system-x86_64 -net dump,id=foo,file=/eperm
qemu-system-x86_64: -net dump,id=foo,file=/eperm: -net dump: can't open /eperm
qemu-system-x86_64: -net dump,id=foo,file=/eperm: Device 'dump' could not be initialized
Convert net_init_tap() to Error. This suppresses the unwanted second
message.
Improve the error messages to include strerror(errno) where
appropriate.

Error reporting for netdev_add is broken: the net_client_init_fun[]
report the actual errors with (at best) error_report(), and their
caller net_client_init1() makes up a generic error on top.
For command line and HMP, this produces an mildly ugly error cascade.
In QMP, the actual errors go to stderr, and the generic error becomes
the command's error reply.
To fix this, we need to convert the net_client_init_fun[] to Error.
To permit fixing them one by one, add an Error ** parameter to the
net_client_init_fun[]. If the call fails without returning an Error,
make up the same generic Error as before. But if it returns one, use
that instead. Since none of them does so far, no functional change.

This patch doesn't seem much useful alone, I must admit. However,
it makes sense as part of the upcoming directory reorganization,
where I want to have include/net/tap.h as the net<->hw interface
for tap. Then having both net/tap.h and include/net/tap.h does
not work. "Fixed" by moving all the init functions to a single
header file net/clients.h.
The patch also adopts a uniform style for including net/*.h files
from net/*.c, without the net/ path.

The vlan feature is no longer part of net core. Rename VLANClientState
to NetClientState because net clients are not explicitly associated with
a vlan at all, instead they have a peer net client to which they are
connected.
This patch is a mechanical search-and-replace except for a few
whitespace fixups where changing VLANClientState to NetClientState
misaligned whitespace.

The net_client_init() prototype is kept intact.
Based on "is_netdev", the QemuOpts-rooted QemuOpt-list is parsed as a
Netdev or a NetLegacy. The original meat of net_client_init() is moved to
and simplified in net_client_init1():
Fields not common between -net and -netdev are clearly separated. Getting
the name for the init functions is cleaner: Netdev::id is mandatory, and
all init functions handle a NULL NetLegacy::name. NetLegacy::vlan
explicitly depends on -net (see below).
Verifying the "type=" option for -netdev can be turned into a switch.
Format validation with qemu_opts_validate() can be removed because the
visitor covers it. Relatedly, the "net_client_types" array is reduced to
an array of init functions that can be directly indexed by opts->kind.
(Help text is available in the schema JSON.)
The outermost negation in the condition around qemu_find_vlan() was
flattened, because it expresses the dependent code's requirements more
clearly.
VLAN lookup is avoided if there's no init function to pass the VLAN to.
Whenever the value of type=... is needed, we substitute
NetClientOptionsKind_lookup[kind].
The individual init functions are not converted yet, thus the original
QemuOpts instance is passed transparently.
v1->v2:
- NetLegacy::name is optional. Tracked it through all init functions: they
all handle a NULL name. Updated commit message accordingly.
v2->v3:
- NetLegacy::id is allowed and takes precedence over NetLegacy::name.

This was done with:

$(git grep -l 'qemu_get_clock\>' )
sed -i 's/qemu_new_timer\>/qemu_new_timer_ns/' \

after checking that get_clock and new_timer never occur twice
on the same line. There were no missed occurrences; however, even
if there had been, they would have been caught by the compiler.
There was exactly one false positive in qemu_run_timers:
- current_time = qemu_get_clock (clock);
+ current_time = qemu_get_clock_ns (clock);
which is of course not in this patch.

error_report() terminates the message with a newline. Strip it it
from its arguments.
This fixes a few error messages lacking a newline:
net_handle_fd_param()'s "No file descriptor named %s found", and
tap_open()'s "vnet_hdr=1 requested, but no kernel support for
IFF_VNET_HDR available" (all three versions).
There's one place that passes arguments without newlines
intentionally: load_vmstate(). Fix it up.
