This switches the tcp, telnet and unix socket support for character
devices (serial/parallel, ...) to the new socket helpers. Thereby they
gain IPv6 support and also get ability to search for a free tcp port.
Syntax is the same as for vnc, using a to= option, like this:
-serial tcp:localhost:5000,to=5099,server
This will check the 5000 -> 5099 port range (inclusive) for a free tcp
port. Likewise you can get auto-allocated unix sockets by specifying an
empty path:
-serial unix:,server
qemu will create a randomly named socket in $TMPDIR then.
tcp also got new "ipv4" and "ipv6" options to make qemu try only the
specified internet protocol version.
You can use the "info chardev" command added by the first patch in this
series to figure the tcp port / unix socket actually allocated.

This patch creates a new source file qemu-sockets.c with a bunch of
helper functions to create listening and connected sockets.
New features of this code are (a) support for searching for a free
port in a given range and (b) support for IPv6.
The following patches put that code into use.

The motivating goal behind this is to allow other tools to use the CharDriver
code. This patch is pure code motion except for the Makefile changes and the
copyright/header in qemu-char.c.
