The 'block-commit' command needs the overlay image of 'top' to
be opened in read-write mode in order to update the backing file
string. If 'top' is not the active layer or its backing file then its
overlay needs to be reopened during the block job.
This is a test case for that scenario.

As of a follow-up patch to this one, the length of a mirror block job
will no longer directly depend on the size of the block device;
therefore, drop these checks from this test. Instead, just check whether
the final offset equals the block job length.
As 041 uses the wait_until_completed function from iotests.py, the same
applies there as well which in turn affects tests 030, 055 and 056. On
the other hand, a block job's length does not have to be related to the
length of the image file in the first place, so that check was
questionable anyway.

Now that active layer block-commit is supported, the 'top' argument
no longer needs to be mandatory.
Change it to optional, with the default being the active layer in the
device chain.

There should be a BLOCK_JOB_READY event with active commit, regardless
of image length. Let's test the 0 length image case, and make sure it
goes through the ready->complete process.

The previous block commit used absolute filenames for all block-commit
images and commands; this adds relative filenames for the same tests.

This simplifies some code and error checking, and also fixes a bug.
bdrv_find_backing_image() should only be passed absolute filenames,
or filenames relative to the chain. In the QMP message handler for
block commit, when looking up the base do so from the determined top
image, so we know it is reachable from top.
Some of the error messages put out by block-commit have changed
slightly, which causes 2 tests cases for block-commit to fail.
This patch updates the test cases to look for the correct error
output.

Derived from the streaming test cases (030), this adds the
following 9 tests:
1. For the following image chain, commit [mid] into [backing],
and use qemu-io to verify [backing] has its original data, as
well as the data from [mid]
[backing] <-- [mid] <-- [test]
2. Verifies that 'block-commit' with the 'speed' parameter sets the
speed parameter, as reported by 'query-block-jobs'
3. Verifies that a bogus 'device' parameter to 'block-commit'
results in error
4-9: Appropriate error values returned for the following argument errors:
* top == base
* top is nonexistent
* base is nonexistent
* top == active layer (this is currently not supported)
* top and base arguments are reversed
* top argument is omitted
