This patch switches the vnc code ofer to the new socket helper
functions.

It adds support IPv6 support and for automatically allocating an unused
vnc display port.  The latter is handled ising a to= option, specifying
the upper limit for the display number to try.  Scanning is started at
the display number given in the display specification, i.e. this command
line:

    -vnc localhost:7,to=11

will try displays 7 to 11 (inclusive).

There are also new "ipv4" and "ipv6" options to make qemu try only
the specified internet protocol version.

The display actually allocated can be queried using the "info vnc"
monitor command.

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.

KVM's live migration support included support for exec: URLs, allowing system
state to be written or received via an arbitrary popen()ed subprocess. This
provides a convenient way to pipe state through a compression algorithm or an
arbitrary network transport on its way to its destination, and a convenient way
to write state to disk; libvirt's qemu driver currently uses migration to exec:
targets for this latter purpose.

This version of the patch refactors now-common code from migrate-tcp.c into
migrate.c.

Currently tap does not generate signals on I/O; this causes
network latency to be dependent on the timer tick (1ms without
dyntick, guest dependent with dyntick).  By generating a signal
on I/O, we can inform the guest immediately that a packet has
arrived.

Bit shuffle operations can be written with very few TCG instructions
(between 5 and 8), so it is worth converting them to TCG.

This code also move all bit shuffle generation code to a separate
function in order to have a cleaner exception code path, that is it
doesn't store back the TCG register to the target register after the
exception, as the TCG register doesn't exist anymore.

On Alpha the target to native fcntl definitions were missing.  Because of
this, programs trying to open files with the O_CREAT option were getting
O_APPEND instead, etc.

This was keeping gcc from the spec benchmarks from running, among other
things.

The cmpbge instruction should compare all 8 bytes of one 64-bit value with
another.  However, we were looping with a < 7 condition which was skipping
the top byte.  So if we were doing a compare where the top byte was
important, we could get the wrong result (this notably breaks the strlen()
function with certain sized strings).
