Kevin Wolf 89a6ceab46 test-bdrv-drain: Test bs->quiesce_counter 
This is currently only working correctly for bdrv_drain(), not for
bdrv_drain_all(). Leave a comment for the drain_all case, we'll address
it later.

Kevin Wolf 86e1c840ec test-bdrv-drain: Test callback for bdrv_drain 
The existing test is for bdrv_drain_all_begin/end() only. Generalise the
test case so that it can be run for the other variants as well. At the
moment this is only bdrv_drain_begin/end(), but in a while, we'll add
another one.

Also, add a backing file to the test node to test whether the operations
work recursively.

Kevin Wolf 881cfd17c7 test-bdrv-drain: Test BlockDriver callbacks for drain 
This adds a test case that the BlockDriver callbacks for drain are
called in bdrv_drained_all_begin/end(), and that both of them are called
exactly once.
