snapshot: new function bdrv_snapshot_find_by_id_and_name()

To make it clear about id and name in searching, add this API

snapshot: distinguish id and name in snapshot delete

Snapshot creation actually already distinguish id and name since it take
a structured parameter *sn, but delete can't. Later an accurate delete

block: introduce bdrv_get_block_status API

For now, bdrv_get_block_status is just another name for bdrv_is_allocated.
The next patches will add more flags.

block: define get_block_status return value

Define the return value of get_block_status. Bits 0, 1, 2 and 9-62
are valid; bit 63 (the sign bit) is reserved for errors. Bits 3-8
are left for future extensions.

The return code is compatible with the old is_allocated API: if a driver...
