snapshot: new function bdrv_snapshot_find_by_id_and_name()

To make it clear about id and name in searching, add this API
to distinguish them. Caller can choose to search by id or name,
*errp will be set only for exception.

Some code are modified based on Pavel's patch....

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
is needed in qmp_transaction abort and blockdev-snapshot-delete-sync,...

block: Image file option amendment

This patch adds the "amend" option to qemu-img which allows changing
image options on existing image files. It also adds the generic bdrv
implementation which is basically just a wrapper for the image format
specific function....

block: remove bdrv_is_allocated_above/bdrv_co_is_allocated_above distinction

Now that bdrv_is_allocated detects coroutine context, the two can
use the same code.

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.

This also touches all block drivers with a mostly mechanical rename. The
sole exception is cow; because it calls cow_co_is_allocated from the read...

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...

block: make bdrv_co_is_allocated static

bdrv_is_allocated can detect coroutine context and go through a fast
path, similar to other block layer functions.
