3cd035d863 GPIO I2C rework
Reqrite bitbanging I2C implementation.  New code improves stop/start
condition handling, and gives more accurate input line level.

Introduce intermediate abstraction layer for I2C bitbanging that
is not connected via a GPIO port.

57a46d0579 Convert linux bootrom to external rom and fw_cfg
We already have a working multiboot implementation that uses fw_cfg to get
its kernel module etc. data in int19 runtime now.

So what's missing is a working linux boot option rom. While at it I figured it
would be a good idea to take the opcode generator out of pc.c and instead use
a proper option rom, like we do with multiboot.

So here it is - an fw_cfg using option rom for -kernel with linux!

77873196f3 Convert multiboot to fw_cfg backed data storage
Right now we load the guest kernel to RAM, fire off the BIOS, hope it
doesn't clobber memory and run an option rom that jumps into the kernel.

That breaks with SeaBIOS, as that clears memory. So let's read all
kernel, module etc. data using the fw_cfg interface when in the int19
handler.

This patch implements said mechanism for multiboot.

c163b5cae9 Block live migration
This patch introduces block migration called during live migration. Block
are being copied to the destination in an async way. First the code will
transfer the whole disk and then transfer all dirty blocks accumulted during
the migration.
Still need to improve transition from the iterative phase of migration to the
end phase. For now transition will take place when all blocks transfered once,
all the dirty blocks will be transfered during the end phase (guest is
suspended).

Changes from v4:
- Global variabels moved to a global state structure allocated dynamically.
- Minor coding style issues.
- Poll block.c for tracking of dirty blocks instead of manage it here.

603987488c PPC64: Partial fix to Linux crash: revert to old devfn
Before 2e29bd0478, Uni-North host and AGP
bridge were using the same devfn, 11 << 3. The net effect was that only
AGP bridge was visible. This was changed in the commit to 13 << 3 for AGP.

Some of the later crashes happened due to NULL pointer dereferences generated
by 07b7d05377 and insufficient return value
checks.

Disable host device and revert AGP to 11 << 3.

4e9df06acc eepro100: Fix boot ROM support
* Rename pxe-eepro100.bin to pxe-i82559er.bin.
  The other devices supported by eepro100.c need
  additional pxe boot ROM images.
* Call rom_add_option during initialisation.
  The code won't work with two or more different
  eepro100 devices, because it only adds one option
  ROM, but this use case is perhaps never needed.

Using this patch, model=i82559er at least works partially.
For full support, more eepro100 patches are needed
(will follow later, can be fetched from ar7 branch
of QEMU).

038eaf82c8 serial: Add interface to set reference oscillator frequency
Many (most?) serial interfaces have a programmable
clock which provides the reference frequency ("baudbase").
So a fixed baudbase which is only set once can be wrong.

omap1.c is an example which could use the new interface
to change baudbase when the programmable clock changes.
ar7 system emulation (still not part of standard QEMU)
is similar to omap and already uses serial_set_frequency.
