This patch replaces get_ticks_per_sec() calls with the macro
NANOSECONDS_PER_SECOND. Also, as there are no callers, get_ticks_per_sec()
is then removed. This replacement improves the readability and
understandability of code.
For example,
timer_mod(fdctrl->result_timer,
qemu_clock_get_ns(QEMU_CLOCK_VIRTUAL) + (get_ticks_per_sec() / 50));
NANOSECONDS_PER_SECOND makes it obvious that qemu_clock_get_ns
matches the unit of the expression on the right side of the plus.

audio_init() should not use hw_error(), because dumping CPU registers
is unhelpful there, and aborting is wrong, because it can be called
called from an audio device's realize() method.
The two uses of hw_error() come from commit 0d9acba:
* When qemu_new_timer() fails. It couldn't fail back then, and it
can't fail now. Drop the unreachable error handling.
* When no_audio_driver can't be initialized. It couldn't fail back
then, and it can't fail now. Replace the error handling by an
assertion.

Enabling this option just creates a playback buffer with the specified settings,
and then ignores it. It's probably some outdated hack to set audio formats on
windows. (The first created stream dictates all other streams settings, at least
on some Windows versions). Setting DAC_FIXED_SETTINGS should have the same
effect as setting (the now removed) primary buffer.

According to MSDN this may happen when the window is not in the foreground, but
the default is 1 since a long time (which means no retries), so it should be ok.
I've found no problems during testing it on Windows 7 and wine, so this was
probably only the case with some old Windows versions.

Setting QEMU_AUDIO_LOG_TO_MONITOR=1 can crash qemu (if qemu tries to log
to the monitor before it's being initialized), and also nothing else in
qemu logs to the monitor.
This log to monitor feature was the last thing that used the default_mon
variable, so I removed it too (as using it can cause problems).

Currently the opaque pointer returned by audio_driver's init is only
exposed to the driver's fini, but not to audio_pcm_ops. This way if
someone wants to share a variable with the driver and the pcm, he must
use global variables. This patch fixes it by adding a third parameter to
audio_pcm_op's init_out and init_in.

When stopping an audio voice, call the audio backend's fini
method before calling audio_pcm_hw_free_resources_ rather than
afterwards. This allows backends which use helper threads (like
pulseaudio) to terminate those threads before the conv_buf or
mix_buf are freed and avoids race conditions where the helper
may access a NULL pointer or freed memory.

.fields = (VMStateField []) {
and
.fields = (VMStateField []) {
Change all the combinations to:

Now that we no longer have MIN_REARM_TIMER_NS a bug in the audio subsys has
clearly shown it self by trying to make a timer fire every nano second.
Note we have a similar problem in 1.6, 1.5 and older but there
MIN_REARM_TIMER_NS limits the wakeups caused by audio being active to
4000 times / second. This still causes a host cpu load of 50 % for simply
playing audio, where as with this patch git master is at 13%, so we should
backport this to 1.5 and 1.6 too.
Note this will not apply to 1.5 and 1.6 as is.
