By reusing the qjson test suite.  After checking that we can demarshal, marshal
again and compared to the expected decoded value.  This doesn't work so well
for floats because they cannot be accurately represented in decimal but we
try our best.

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: Anthony 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

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.

Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

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.

Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

Only two callers of pci_create_simple/pci_register_device bothered
to check the return value. Other cases were prone to crashing with
spurious NULL pointer dereferences.

Make QEMU exit with an error message when devfn is attempted to
be duplicated, also applies to case when the bus is full. Remove
checks.
