i2c: Allow I2C devices to NAK start events
...
Add a return value to the event handler. Some I2C devices will
NAK if they have no data, so allow them to do this. This required
the following changes:
Go through all the event handlers and change them to return int
and return 0.
Modify i2c_start_transfer to terminate the transaction on a NAK.
Modify smbus handing to not assert if a NAK occurs on a second
operation, and terminate the transaction and return -1 instead.
Add some information on semantics to I2CSlaveClass.

i2c: Factor our send() and recv() common logic
...
Most of the control flow logic between send and recv (error checking
etc) is the same. Factor this out into a common send_recv() API.
This is then usable by clients, where the control logic for send
and receive differs only by a boolean. E.g.
if (send)
i2c_send(...):
else
i2c_recv(...);
becomes:
i2c_send_recv(... , send);

hw: move headers to include/
...
Many of these should be cleaned up with proper qdev-/QOM-ification.
Right now there are many catch-all headers in include/hw/ARCH depending
on cpu.h, and this makes it necessary to compile these files per-target.
However, fixing this does not belong in these patches.
