Some time ago, the last time which did not have dynticks was removed,
so now all timers have dynticks.
I also removed a misleading error message for the dynticks timer.
If timer_create fails, there is already an error message, and
QEMU will use the unix timer which also provides dynamic ticks,
therefore dynamic ticks are not disabled.
v2:
Remove two if statements because they were always true
(thanks to Paolo Bonzini for this correction).

Fix win32_rearm_timer and mm_rearm_timer: they should be able to handle
INT64_MAX as a delta parameter without overflowing.
Also, the next deadline in ms should be calculated rounding down rather
than up (see unix_rearm_timer and dynticks_rearm_timer).
Finally ChangeTimerQueueTimer takes an unsigned long and timeSetEvent
takes an unsigned int as delta, so cast the ms delta to the appropriate
unsigned integer.

It's identical to the hda-duplex codec, except that it advertises the
input as microphone instead of line-in and the output as speaker instead
of line-out. Some guest apps (microsoft netmeeting being one) are picky
when it comes to selecting the recording source and don't accept
line-in, so give them what they expect.

If a guest sets very short timeouts, and asks for a timer to be reloaded on
timeout, QEMU can go to 100%CPU utilisation and become unresponsive,
as it is spending all its time generating timeout interrupts. On real
hardware this doesn't matter, as the interrupts are just coalesced,
and the effect is to have the interrupt asserted all the time.
This patch is a band-aid, that prevents timeouts less than 10
microseconds from being set. 10 microseconds is a limit that was
determined empirically on a variety of machines as the shortest that
allowed QEMU to pick up a control-a c sequence to get at the monitor.

Now only the qemu_*dir variables will become #defines. The other
directory names aren't used by the C code.
That means the following #defines won't be available in C code anymore:
- CONFIG_QEMU_BINDIR
- CONFIG_QEMU_LIBDIR
- CONFIG_QEMU_INCLUDEDIR
- CONFIG_QEMU_MANDIR
- CONFIG_QEMU_SYSCONFDIR
- CONFIG_QEMU_LIBEXECDIR
The following #defines are going to be kept because they are handled by
the qemu_* block on create_config:
- CONFIG_QEMU_CONFDIR
- CONFIG_QEMU_DATADIR
- CONFIG_QEMU_DOCDIR
This one will be kept because it is set directly by ./configure:
- CONFIG_QEMU_HELPERDIR
This patch keeps the 'prefix=*' (CONFIG_QEMU_PREFIX) pattern because
other variables may use $prefix on their config-host.mak definitions.
The remaining code will be simplified on a further patch.
