configure: Default to 'cc', not 'gcc'
Default to 'cc' as our compiler, rather than 'gcc'. We used to have
to insist on gcc when we still kept the CPU env in a fixed global
register, but this is no longer necessary and we will now compile OK
on clang as well as gcc. Using 'cc' should generally result in us
using the most standard and maintained system compiler for the
platform. (For instance on newer MacOS X 'gcc' exists but is an
elderly compiler provided mostly for legacy reasons, and 'cc'
(which is clang) is definitely the better choice.) On Linux there
will generally be no user-visible change since cc will be gcc.
This changeover necessitates a slight reworking of how we set the
'cc' variable, because GNU cross toolchains generally provide a
'${cross_prefix}gcc' but not a '${cross_prefix}cc'.

usb-tablet: Allow connecting to ehci
Our ehci code has is capable of significantly lowering the wakeup rate
for the hcd emulation while the device is idle. It is possible to add
similar code ot the uhci emulation, but that simply is not there atm,
and there is no reason why a (virtual) usb-tablet can not be a USB-2 device.
Making usb-hid devices connect to the emulated ehci controller instead
of the emulated uhci controller on vms which have both lowers the cpuload
for a fully idle vm from 20% to 2-3% (on my laptop).
An alternative implementation to using a property to select the tablet
type, would be simply making it a new device type, ie usb-tablet2, but the
downside of that is that this will require libvirt changes to be available
through libvirt at all, and then management tools changes to become the
default for new vms, where as using a property will automatically get
any pc-1.3 type vms the lower cpuload.

ehci: Lower timer freq when the periodic schedule is idle
Lower the timer freq if no iso schedule packets complete for 64 frames in
a row.
We can safely do this, without adding latency, because:
1) If there is isoc traffic this will never trigger
2) For async handled interrupt packets (only usb-host), the completion handler
will immediately schedule the frame_timer from a bh
3) All devices using NAK to signal no data for interrupt endpoints now use
wakeup, which will immediately schedule the frame_timer from a bh
The advantage of this is that when we only have interrupt packets in the
periodic schedule, async_stepdown can do its work and significantly lower
the frequency at which the frame_timer runs.

usb: Don't allow USB_RET_ASYNC for interrupt packets
It is tempting to use USB_RET_ASYNC for interrupt packets, rather then the
current NAK + polling approach, but this causes issues for migration, as
an async completed packet will not getting written back to guest memory until
the next poll time, and if a migration happens in between it will get lost!
Make an exception for host devices, because:
1) host-linux actually uses async completion for interrupt endpoints
2) host devices don't migrate anyways
Ideally we would convert host-linux.c to handle (input) interrupt endpoints in
a buffered manner like it does for isoc endpoints, keeping multiple urbs
submitted to ensure the devices timing requirements are met, as well as making
its interrupt ep handling the same as other usb-devices.
