A package from pri_indev or sec_indev only belongs to a particular
Connection, so we only need to compare the package in the specified
Connection's primary_list and secondary_list, rather than for each
the whole Connection list to compare. This is time-consuming and
unnecessary.
Less checkpoint more efficiency.

Currently, a packet from pri_dev or sec_dev is fristly pushed at the
tail of the primary or secondary packet queue then sorted by the tcp
sequence number.
Now, this patch use g_queue_insert_sorted to insert the packet directly
into the suitable position to avoid ordering all packets each time when
a new packet is comming, thereby increasing efficiency.
In addition, consolidate the code that add a packet to the list of
Connection (primary or secondary) into a separate routine colo_insert_packet()
since the same chunk of code is called from two place.

Since commit 0f8c289ad "net: fix -netdev socket,fd= for UDP sockets"
we allow more than one parameter for -netdev socket. But now
we run into an assert when no parameter at all is specified
> qemu-system-x86_64 -netdev socket
socket.c:729: net_init_socket: Assertion `sock->has_udp' failed.
Fix this by reverting the change of the if condition done in 0f8c289ad.

When using filter-mirror like the example below where the interface
'ndev0' does not exist on the host, QEMU crashes into segmentation
fault.
$ qemu-system-x86_64 -S -machine pc -netdev user,id=ndev0 -object filter-mirror,id=test-object,netdev=ndev0
This happens because the function filter_mirror_setup() does not check
if the device actually exists and still keep on processing calling
qemu_chr_find(). This patch fixes this issue.

Convert all the multi-line uses of fprintf(stderr, "warning:"..."\n"...
to use warn_report() instead. This helps standardise on a single
method of printing warnings to the user.
All of the warnings were changed using these commands:
find ./* -type f -exec sed -i \
'N; {s|fprintf(.*".*warning[,:] \(.*\)\\n"\(.*\));|warn_report("\1"\2);|Ig}' \
{} +
find ./* -type f -exec sed -i \
'N;N; {s|fprintf(.*".*warning[,:] \(.*\)\\n"\(.*\));|warn_report("\1"\2);|Ig}' \
{} +
find ./* -type f -exec sed -i \
'N;N;N; {s|fprintf(.*".*warning[,:] \(.*\)\\n"\(.*\));|warn_report("\1"\2);|Ig}' \

find ./* -type f -exec sed -i \
'N;N;N;N;N;N;N; {s|fprintf(.*".*warning[,:] \(.*\)\\n"\(.*\));|warn_report("\1"\2);|Ig}' \
{} +
Indentation fixed up manually afterwards.
Some of the lines were manually edited to reduce the line length to below
80 charecters. Some of the lines with newlines in the middle of the
string were also manually edit to avoid checkpatch errrors.
The #include lines were manually updated to allow the code to compile.
Several of the warning messages can be improved after this patch, to
keep this patch mechanical this has been moved into a later patch.

pactkets of the primary
Remove the task which check old packet in the comparing thread,
then use IOthread context timer to handle it.
Process pactkets in the IOThread which arrived over the socket.
we use iothread_get_g_main_context to create a new g_main_loop in
the IOThread.then the packets from the primary and the secondary
are processed in the IOThread.
Finally remove the colo-compare thread using the IOThread instead.

When -net socket fails, it first reports a specific error, then
a generic one, like this:
$ ./x86_64-softmmu/qemu-system-x86_64 -net socket,mcast=230.0.0.1:1234,listen
qemu-system-x86_64: -net socket,mcast=230.0.0.1:1234,listen: exactly one of listen=, connect=, mcast= or udp= is required
qemu-system-x86_64: -net socket,mcast=230.0.0.1:1234,listen: Device 'socket' could not be initialized
Convert net_socket_*_init() to Error to get rid of the superfluous second
error message. After the patch, the effect like this:
$ ./x86_64-softmmu/qemu-system-x86_64 -net socket,mcast=230.0.0.1:1234,listen
qemu-system-x86_64: -net socket,mcast=230.0.0.1:1234,listen: exactly one of listen=, connect=, mcast= or udp= is requireda
This also fixes a few silent failures to report an error.

In net_socket_fd_init(), the 'default' case is odd: it warns,
then continues as if the socket type was SOCK_STREAM. The
comment explains "this could be a eg. a pty", but that makes
no sense. If @fd really was a pty, getsockopt() would fail
with ENOTSOCK. If @fd was a socket, but neither SOCK_DGRAM nor
SOCK_STREAM. It should not be treated as if it was SOCK_STREAM.
Turn this case into an Error. If there is a genuine reason to
support something like SOCK_RAW, it should be explicitly
handled.

Currently, a FOO_lookup is an array of strings terminated by a NULL
sentinel.
A future patch will generate enums with "holes". NULL-termination
will cease to work then.
To prepare for that, store the length in the FOO_lookup by wrapping it
in a struct and adding a member for the length.
The sentinel will be dropped next.

if (trace_event_get_state(TRACE_MY_EVENT)) {
str = g_strdup_printf("Expensive string to generate ...",
...);
trace_my_event(str);
g_free(str);
}
Add trace_event_get_state_backends() to fetch backend dstate. Those

generate_h_backend_dstate().

trace_event_get_state_backends() instead.

We add the vnet_hdr_support option for filter-redirector, default is disabled.
If you use virtio-net-pci net driver or other driver needs vnet_hdr, please enable it.
Because colo-compare or other modules needs the vnet_hdr_len to parse
packet, we add this new option send the len to others.
You can use it for example:
-object filter-redirector,id=r0,netdev=hn0,queue=tx,outdev=red0,vnet_hdr_support

We add the vnet_hdr_support option for filter-mirror, default is disabled.
If you use virtio-net-pci or other driver needs vnet_hdr, please enable it.
You can use it for example:
-object filter-mirror,id=m0,netdev=hn0,queue=tx,outdev=mirror0,vnet_hdr_support
If it has vnet_hdr_support flag, we will change the sending packet format from
struct {int size; const uint8_t buf[];} to {int size; int vnet_hdr_len; const uint8_t buf[];}.
make other module(like colo-compare) know how to parse net packet correctly.

Convert all uses of error_report("warning:"... to use warn_report()
instead. This helps standardise on a single method of printing warnings
to the user.
All of the warnings were changed using these two commands:
find ./* -type f -exec sed -i \
's|error_report(".*warning[,:] |warn_report("|Ig' {} +
Indentation fixed up manually afterwards.
The test-qdev-global-props test case was manually updated to ensure that
this patch passes make check (as the test cases are case sensitive).

Use the actual unsigned integer type name.
The type name change impacts the following externally visible area:
* vl.c's machine_help_func() puts it in help for -machine NAME,help.
* QMP command qom-list exposes it in ObjectPropertyInfo member @type.
* QMP command device-list-properties exposes it in DevicePropertyInfo
member @type.

This reverts commit 883e4f7624e10b98d16d9adaffb8b1795664d899.
This code changed net/socket.c from using socket()+connect(),
to using socket_connect(). In theory this is great, but in
practice this has completely broken the ability to connect
the frontend and backend:
$ ./x86_64-softmmu/qemu-system-x86_64 \
-device e1000,id=e0,netdev=hn0,mac=DE:AD:BE:EF:AF:05 \
-netdev socket,id=hn0,connect=localhost:1234
qemu-system-x86_64: -device e1000,id=e0,netdev=hn0,mac=DE:AD:BE:EF:AF:05: Property 'e1000.netdev' can't find value 'hn0'
The old code would call net_socket_fd_init() synchronously,
while letting the connect() complete in the backgorund. The
new code moved net_socket_fd_init() so that it is only called
after connect() completes in the background.
Thus at the time we initialize the NIC frontend, the backend
does not exist.
The socket_connect() conversion as done is a bad fit for the
current code, since it did not try to change the way it deals
with async connection completion. Rather than try to fix this,
just revert the socket_connect() conversion entirely.
The code is about to be converted to use QIOChannel which
will let the problem be solved in a cleaner manner. This
revert is more suitable for stable branches in the meantime.

This simplifies removing a backend for a frontend user (no need to
retrieve the associated driver and separate delete call etc).
NB: many frontends have questionable handling of ending a chardev. They
should probably delete the backend to prevent broken reusage.
