  sockets: add helpers for creating SocketAddress from a socket

Add two helper methods that, given a socket file descriptor,
can return a populated SocketAddress struct containing either
the local or remote address information.

  sockets: move qapi_copy_SocketAddress into qemu-sockets.c

The qapi_copy_SocketAddress method is going to be useful
in more places than just qemu-char.c, so move it into
the qemu-sockets.c file to allow its reuse.

  sockets: allow port to be NULL when listening on IP address

If the port in the SocketAddress struct is NULL, it can allow
the kernel to automatically select a free port. This is useful
in particular in unit tests to avoid a race trying to find a
free port to run a test case on.

  ui: convert VNC startup code to use SocketAddress

The VNC code is currently using QemuOpts to configure the
sockets connections / listeners it needs. Convert it to
use SocketAddress to bring it in line with modern QAPI
based code elsewhere in QEMU.

  osdep: add qemu_fork() wrapper for safely handling signals

When using regular fork() the child process of course inherits
all the parents' signal handlers. If the child then proceeds
to close() any open file descriptors, it may break some of those
registered signal handlers. The child generally does not want to
ever run any of the signal handlers that the parent may have
installed in the short time before it exec's. The parent may also
have blocked various signals which the child process will want
enabled.

This introduces a wrapper qemu_fork() that takes care to sanitize
signal handling across fork. Before forking it blocks all signals
in the parent thread. After fork returns, the parent unblocks the
signals and carries on as usual. The child, however, resets all the
signal handlers back to their defaults before it unblocks signals.
The child process can now exec the binary in a "clean" signal
environment.

  coroutine: move into libqemuutil.a library

The coroutine files are currently referenced by the block-obj-y
variable. The coroutine functionality though is already used by
more than just the block code. eg migration code uses coroutine
yield. In the future the I/O channel code will also use the
coroutine yield functionality. Since the coroutine code is nicely
self-contained it can be easily built as part of the libqemuutil.a
library, making it widely available.

The headers are also moved into include/qemu, instead of the
include/block directory, since they are now part of the util
codebase, and the impl was never in the block/ directory
either.
