Add hid_has_events function, use it to figure whenever there are pending
events instead of checking and updating USBHIDState->changed.

Setting ->changed to 1 on init is removed, that should have absolutely
no effect as the initial state of ->idle is 0 so we report hid state
anyway until the guest configures some idle time.  Also should clear
->idle on reset.

Add callback for event notification, which allows to un-usbify more
functions.  Also split separate hid_* functions for reset and release.
Signed-off-by: NGerd Hoffmann <kraxel@redhat.com>

First step in separating out the HID emulation code from usb-hid, so it
can be reused without creating a dummy usb device like bluetooth does.

This creates a HIDState struct, moves the non-usbish fields from
USBHIDStruct there.  Renames non-usbish structs, defines and functions
from usb* to hid*.  Adapts the code to that.

Also cleans up a bunch of code style issues along the way.

Map guest memory and pass on a direct pointer instead of copying
the bits to a indirect buffer.  EHCI transfer descriptors can
reference multiple (physical guest) pages so we'll actually start
seeing usb packets wich carry iovec with more than one element.

Zap data pointer from USBPacket, add a QEMUIOVector instead.
Add a bunch of helper functions to manage USBPacket data.
Switch over users to the new interface.

Note that USBPacket->len was used for two purposes:  First to
pass in the buffer size and second to return the number of
transfered bytes or the status code on async transfers.  There
is a new result variable for the latter.  A new status code
was added to catch uninitialized result.

Nobody creates iovecs with more than one element (yet).
Some users are (temporarely) limited to iovecs with a single
element to keep the patch size as small as possible.

Commit b14ef7c9
introduced cpu_unassigned_access() function. On Sparc,
the function does not restore AREG0 used for global CPUState
on function exit, causing bugs with non-faulting unassigned
memory accesses. Alpha, Microblaze and MIPS are not affected.

Fix by restoring AREG0 on exit. Remove excess saving by
do_unassigned_access() functions.

Also ignore unassigned accesses outside of CPU context.

This patch almost rewrites acpi_table_add() function
(but still leaves it using old get_param_value() interface).
The result is that it's now possible to specify whole table
(together with a header) in an external file, instead of just
data portion, with a new file= parameter, but at the same time
it's still possible to specify header fields as before.

Now with the checkpatch.pl formatting fixes, thanks to
Stefan Hajnoczi for suggestions, with changes from
Isaku Yamahata, and with my further refinements.
