This causes ctrl+alt+u or ctrl+alt+f to not work when windows hasn't been
resized first. Other graphic emulators do resize the screen on
hw_invalidate.
Fix cpu_get_real_ticks:
- check should be done on __mips and not __mips_isa_rev
- linux kernels >= 2.6.25 are emulating the 2 needed rdhwr functions
so it's safe to use rdhwr.

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.

(qemu) migrate -d -b tcp:0:4444 # for live migration with complete storage copy
(qemu) migrate -d -i tcp:0:4444 # for live migration with incremental storage copy, storage is cow based.

This patch introduces block migration called during live migration. Block

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).

- Minor coding style issues.

char: don't limit data sent to backends to 1k per buffer
chardevs have a 'can_read' function via which backends specify
the amount of data they can receive. When can_read returns > 0,
apps can start sending data. However, each chardev driver here
allows a max. of 1k bytes inspite of the backend being able to
receive more.
The best we can do here is to allocate s->max_size bytes from
the heap on each call (which is the number returned by the
backend from the can_read call).
This is an intermediate step to bump up the bytes written in
