Add a separate tracepoint to log how register values change in response
to a mmio write. Especially useful for registers which have read-only
or clear-on-write bits in them.

Add functions to get and set the current state of the state machine,
add tracepoints there to trace state transitions. Add support for

Drop a few DPRINTFs and all DPRINTF_ST lines, they are obsolete now.

This patch starts adding trace support to ehci. It traces
updates of the status register (USBSTS), mmio access and
controller reset.
It also adds functions to set and clear status register bits
and puts them in use everywhere.
Some DPRINTF's are dropped in favor of the new tracepoints.
No change in behavior.

Changes since v1: create a wrapper function named qemu_daemon() in oslib-posix.c
instead of putting the OS specific workaround in qemu-nbd.c directly.
On OSX >= 10.5, daemon() is deprecated, resulting in the following warning:
----8<----
qemu-nbd.c: In function ‘main’:
qemu-nbd.c:371: warning: ‘daemon’ is deprecated (declared at /usr/include/stdlib.h:289)
----8<----
The following trick, used in mDNSResponder, takes care of this warning:
http://www.opensource.apple.com/source/mDNSResponder/mDNSResponder-258.18/mDNSPosix/PosixDaemon.c
On OSX, it temporarily renames the daemon() function before including stdlib.h
and declares it manually as an extern function. This way, the compiler does not
see the declaration from stdlib.h and thus does not display the warning.

This fixes a missing prototype warning in vl.c and obsoletes
the prototype in cocoa.m. Adjust callers in cocoa.m to supply
third argument, which is currently only used on Linux/ppc.
The prototype is designed so that it could be shared with SDL
and other frontends, if desired.

Under Darwin, a symbol exists for the fdatasync() function, so that our
link test succeeds. However _POSIX_SYNCHRONIZED_IO is set to '-1'.
According to POSIX:2008, a value of -1 means the feature is not supported.
A value of 0 means supported at compilation time, and a value greater 0
means supported at both compilation and run time.
Enable fdatasync() only if _POSIX_SYNCHRONIZED_IO is '>0'.

The virtio_queue_notify() function checks that the virtqueue number is
less than the maximum number of virtqueues. A signed comparison is used
but the virtqueue number could be negative if a buggy or malicious guest
is run. This results in memory accesses outside of the virtqueue array.
It is risky doing input validation in common code instead of at the
guest<->host boundary. Note that virtio_queue_set_addr(),
virtio_queue_get_addr(), virtio_queue_get_num(), and many other virtio
functions do *not* validate the virtqueue number argument.
Instead of fixing the comparison in virtio_queue_notify(), move the
comparison to the virtio bindings (just like VIRTIO_PCI_QUEUE_SEL) where
we have a uint32_t value and can avoid ever calling into common virtio
code if the virtqueue number is invalid.
