frindex is a 14 bits counter, so bits 31-14 should always be 0, and
after the commit titled "usb-ehci: frindex always is a 14 bits counter"
we rely on frindex always being a multiple of 8. I've not seen this in
practice, but theoretically a guest can write a value >= 0x4000 or a value
which is not a multiple of 8 value to frindex, this patch ensures that
things will still work when that happens.

To answer the question in the comment removed by this patch:  I think
this was needed because several places in the ehci emulation did not
check the T bit of link entries correctly and thus might have followed
invalid references.  See commit 2a5ff735Signed-off-by: NGerd Hoffmann <kraxel@redhat.com>

Our hda codecs exist in two variants:  With CONFIG_MIXEMU=y they expose
amplifiers for volume control to the guest, with CONFIG_MIXEMU=n they
don't.

This patch changes the codec ids, they are different now for these two
cases.  This makes sure windows guests will notice the difference.

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.

$confdir is a confusing name, as it's not clear if it's "the system
config dir" or "the Qemus-specific directory inside the config dir".
$qemu_confdir makes it more clear.

The current C code that uses CONFIG_QEMU_CONFDIR should be safe, as now
create_config generates the same #define name (CONFIG_QEMU_CONFDIR) for
both "confdir" and "qemu_confdir" variables.

The generic *dir section will eventually go away and be replaced with
qemu_* section. By now, both sections will be kept, while the variables
get renamed on config-host.mak.

With this patch, a XXXdir variable will become a CONFIG_QEMU_XXXDIR
define, and a qemu_XXXdir variable will become CONFIG_QEMU_XXXDIR as
well (instead of becoming a CONFIG_QEMU_QEMU_XXXDIR define).
