The current code includes assert.h very early (from qemu-common.h),
so the definition of NDEBUG was without any effect.
In the initial version from 2004, NDEBUG was used to disable the assertions.
Those assertions are not in time critical code, so it is no longer
reasonable to disable them and the definition of NDEBUG can be removed.
Type u16 is also unused and therefore does not need a type definition.

This patch adds sync-modes to the drive-backup interface and
implements the FULL, NONE and TOP modes of synchronization.
FULL performs as before copying the entire contents of the drive
while preserving the point-in-time using CoW.
NONE only copies new writes to the target drive.
TOP copies changes to the topmost drive image and preserves the
point-in-time using CoW.
For sync mode TOP are creating a new target image using the same backing
file as the original disk image. Then any new data that has been laid
on top of it since creation is copied in the main backup_run() loop.
There is an extra check in the 'TOP' case so that we don't bother to copy
all the data of the backing file as it already exists in the target.
This is where the bdrv_co_is_allocated() is used to determine if the
data exists in the topmost layer or below.
Also any new data being written is intercepted via the write_notifier
hook which ends up calling backup_do_cow() to copy old data out before
it gets overwritten.
For mode 'NONE' we create the new target image and only copy in the
original data from the disk image starting from the time the call was
made. This preserves the point in time data by only copying the parts
that are *going to change* to the target image. This way we can
reconstruct the final image by checking to see if the given block exists
in the new target image first, and if it does not, you can get it from
the original image. This is basically an optimization allowing you to
do point-in-time snapshots with low overhead vs the 'FULL' version.
Since there is no old data to copy out the loop in backup_run() for the
NONE case just calls qemu_coroutine_yield() which only wakes up after
an event (usually cancel in this case). The rest is handled by the
before_write notifier which again calls backup_do_cow() to write out
the old data so it can be preserved.

The old 'cache' option really encodes three different boolean flags into
a cache mode name, without providing all combinations. Make them three
separate options instead and translate the old option to the new ones
for drive_init().
The specific boolean options take precedence if the old cache option is
specified as well, so the following options are equivalent:
-drive file=x,cache=none,cache.no-flush=true
-drive file=x,cache.writeback=true,cache.direct=true,cache.no-flush=true

The discriminator for anonymous unions is the data type. This allows to
have a union type that allows both of these:
{ 'file': 'my_existing_block_device_id' }
{ 'file': { 'filename': '/tmp/mydisk.qcow2', 'read-only': true } }
Unions like this are specified in the schema with an empty dict as
discriminator. For this example you could take:
{ 'union': 'BlockRef',
'discriminator': {},
'data': { 'definition': 'BlockOptions',
'reference': 'str' } }
{ 'type': 'ExampleObject',
'data: { 'file': 'BlockRef' } }

The new 'base' key in a union definition refers to a struct type, which
is inlined into the union definition and can represent fields common to
all kinds.
For example the following schema definition...
{ 'type': 'BlockOptionsBase', 'data': { 'read-only': 'bool' } }
{ 'union': 'BlockOptions',
'base': 'BlockOptionsBase',
'data': {
'raw': 'BlockOptionsRaw'
'qcow2': 'BlockOptionsQcow2'
} }
...would result in this generated C struct:
struct BlockOptions
{
BlockOptionsKind kind;
union {
void *data;
BlockOptionsRaw * raw;
BlockOptionsQcow2 * qcow2;
};
bool read_only;
};
