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!

We will have a linux boot option rom soon, so let's take all functionality
that might be useful for both to a header file that both roms can include.

That way we only have to write fw_cfg access code once.

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.

This is the third and final stage of the JSON parser.  It parses lexical tokens
performing grammar validation and creating the final QObject representation.  It
uses a recursive decent parser.

The second stage of our JSON parser is a simple state machine that identifies
individual JSON values by counting the levels of nesting of tokens.  It does
not perform grammar validation.  We use this to emit a full JSON value to the
parser.
Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>

Our JSON parser is a three stage parser.  The first stage tokenizes the stream
into a set of lexical tokens.  Since the lexical grammar is regular, we can
use a finite state machine to model it.  The state machine will emit tokens
as they are identified.

This patch adds the option to activate non-shared storage migration from the
monitor.
The migration command is as follows:
(qemu) migrate -d tcp:0:4444 # for ordinary live migration
(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.

Changes from v4:
- Minor coding style issues.

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.

To support live migration without shared storage we need to be able to trace
writes to disk while migrating. This Patch expose dirty block tracking per
device to be polled from upper layer.

Changes from v4:
- Register dirty tracking for each block device.
- Minor coding style issues.
- Block.c will now manage a dirty bitmap per device once
  bdrv_set_dirty_tracking() is called. Bitmap is polled by the upper
  layer (block-migration.c).

This function sends out the OPENED event to backends that
have drive the chardevs. The 'reset' is now a historical

The initial_reset sent to chardevs doesn't do much other than setting
a bool to true. Char devices are interested in the open event and
that gets sent whenever the device is opened.

Moreover, the reset logic breaks as and when qemu's bh scheduling
changes.

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
each call to 4k.

Before 2e29bd04, 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 07b7d053 and insufficient return value
checks.

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