bitbang_i2c: avoid call to sysbus_init_mmio()
Instead of calling sysbus_init_mmio() with a null region,create a dummy region using the memory API.
Use glib memory allocation and free functions
qemu_malloc/qemu_free no longer exist after this commit.

bitbang_i2c: Fix spurious slave read after NACK
After NACKing a read operation, a raising SCL should not trigger a newread from the slave. Introduce a new state which just waits for a stopor start condition after NACK.

GPIO I2C rework
Reqrite bitbanging I2C implementation. New code improves stop/startcondition handling, and gives more accurate input line level.
Introduce intermediate abstraction layer for I2C bitbanging thatis not connected via a GPIO port.

qdev: add return value to init() callbacks.
Sorry folks, but it has to be. One more of these invasive qdev patches.
We have a serious design bug in the qdev interface: device initcallbacks can't signal failure because the init() callback has noreturn value. This patch fixes it....
Extract musicpal.c I2C bitbanging code and make it gpio aware
