It's unused now (except for permission handling)[*]. The only reasonable
user of it was block-stream job, recently updated to use own blk. And
other block jobs prefer to use own source node related objects.

So, the arguments of dropping the field are:

 - block jobs prefer not to use it
 - block jobs usually has more then one node to operate on, and better
   to operate symmetrically (for example has both source and target
   blk's in specific block-job state structure)

*: BlockJob.blk is used to keep some permissions. We simply move
permissions to block-job child created in block_job_create() together
with blk.

In mirror, we just should not care anymore about restoring state of
blk. Most probably this code could be dropped long ago, after dropping
bs->job pointer. Now it finally goes away together with BlockJob.blk
itself.

iotest 141 output is updated, as "bdrv_has_blk(bs)" check in
qmp_blockdev_del() doesn't fail (we don't have blk now). Still, new
error message looks even better.

In iotest 283 we need to add a job id, otherwise "Invalid job ID"
happens now earlier than permission check (as permissions moved from
blk to block-job node).

Notes:

1. Of course, tests can't run simultaneously in same TEST_DIR. So,
   use subdirectories TEST_DIR/testname/ and SOCK_DIR/testname/
   instead of simply TEST_DIR and SOCK_DIR

2. multiprocessing.Pool.starmap function doesn't support passing
   context managers, so we can't simply pass "self". Happily, we need
   self only for read-only access, and it just works if it is defined
   in global space. So, add a temporary link TestRunner.shared_self

These filter tests need a NIC, no matter which one, so they use a common
NIC by default. However, these common NIC models might not always have
been compiled into the QEMU target binary, so assuming that a certain NIC
is available is a bad idea. Since the exact type of NIC does not really
matter for these tests, let's switch to "-nic" instead of "-netdev" so
that QEMU can simply pick a default NIC for us.
This way we can now run the tests on other targets that have a default
machine with an on-board/default NIC, too.

The only difference between the two, as far as either configure or

For tests/tcg, specify the endianness explicitly on the command line;
for configure, do the same so that it is possible to have --cpu=ppc64le
on a bigendian system or vice versa.  Apart from this, cpu=ppc64le can
be normalized to ppc64 also in configure and not just in the meson
cross file.
