aio_poll() must return true if any work is still pending, even if it
didn't make progress, so that bdrv_drain_all() doesn't stop waiting too
early. The possibility of stopping early occasionally lead to a failed
assertion in bdrv_drain_all(), when some in-flight request was missed
and the function didn't really drain all requests.
In order to make that change, the return value as specified in the
function comment must change for blocking = false; fortunately, the
return value of blocking = false callers is only used in test cases, so
this change shouldn't cause any trouble.

This is a bug that was caught by a coverity run by Markus. In
the error case when we errored out to exit_restore_open early in the
function, 'overlay_bs' was still NULL at that point, although it is
used to look up flags and perform a bdrv_reopen().
Move the overlay_bs lookup to where it is needed, and check for NULL
before restoring the flags. Also get rid of the unneeded parameter
initialization.

An early length postincrement in the TMP105's I2C TX path led to
transfers of more than one byte to place the second byte in the third
byte's place within the buffer and the third byte to get discarded.
Fix this by explictly incrementing the length after the checks but
before the callback is called, which again checks the length.

qemu_chr_open_socket is split into two functions. All initialization
after creating the socket file handler is split away into the new
qemu_chr_open_socket_fd function.
chr->filename doesn't get filled from QemuOpts any more. Qemu gathers
the information using getsockname and getnameinfo instead. This way it
will also work correctly for file handles passed via file descriptor
passing.
Finally qmp_chardev_open_socket() is the actual qmp hotplug
implementation which basically just calls socket_listen or
socket_connect and the new qemu_chr_open_socket_fd function.

guest's non-volatile memory location in case no boot order is
