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 883e4f7624.
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.

Move all the frontend struct and methods to a seperate unit. This avoids
accidentally mixing backend and frontend calls, and helps with readabilty.
Make qemu_chr_replay() a macro shared by both char and char-fe.
Export qemu_chr_write(), and use a macro for qemu_chr_write_all()
(nb: yes, CharBackend is for char frontend :)

Because filter_mirror_receive_iov() and filter_redirector_receive_iov()
both use the filter_mirror_send() to send packet, so I change
filter_mirror_send() to filter_send() that looks more common.
And fix some codestyle.

gcc 7 (on fedora 26) objects to many of the snprintf's
in the smb path and command creation because it can't
figure out that the smb_dir (i.e. the /tmp dir for the configuration)
is known to be short.
Replace all these fixed length buffers by g_str* functions that dynamically
allocate and use g_dir_make_tmp to make the directory.
(It's fairly new glib but we have a compat function for it).

The OS will allocate automatically a free port. This is useful if you
want to be sure to not get any port conflict. You still have to figure
out which port you got, for example with "lsof" (this could be exposed
in the monitor if needed).
Example of use:
$ qemu-system-x86_64 -net user,hostfwd=127.0.0.1:0-:22 ...
Then, get your port with:
$ lsof -np 1474 | grep LISTEN
qemu-syst 31777 bernat 12u IPv4 [...] TCP 127.0.0.1:35145 (LISTEN)

This reverts commit 0fc8aec7de.
In commit 2dfe5113b1 we split a trace event with a lot of arguments
in two, because the UST trace backend has a limit on the number
of arguments you can have in a single trace event. Unfortunately
we subsequently forgot about this, and in commit 0fc8aec7de
we merged the two trace events again, recreating the "UST backend
doesn't build" bug.
