fbaa6bb3d3 qcow2: Optimize write zero of unaligned tail cluster
We've already improved discards to operate efficiently on the tail
of an unaligned qcow2 image; it's time to make a similar improvement
to write zeroes.  The special case is only valid at the tail
cluster of a file, where we must recognize that any sectors beyond
the image end would implicitly read as zero, and therefore should
not penalize our logic for widening a partial cluster into writing
the whole cluster as zero.

However, note that for now, the special case of end-of-file is only
recognized if there is no backing file, or if the backing file has
the same length; that's because when the backing file is shorter
than the active layer, we don't have code in place to recognize
that reads of a sector unallocated at the top and beyond the backing
end-of-file are implicitly zero.  It's not much of a real loss,
because most people don't use images that aren't cluster-aligned,
or where the active layer is a different size than the backing
layer (especially where the difference falls within a single cluster).

Update test 154 to cover the new scenarios, using two images of
intentionally differing length.

While at it, fix the test to gracefully skip when run as
./check -qcow2 -o compat=0.10 154
since the older format lacks zero clusters already required earlier
in the test.

e249d51952 iotests: Add test 179 to cover write zeroes with unmap
No tests were covering write zeroes with unmap.  Additionally,
I needed to prove that my previous patches for correct status
reporting and write zeroes optimizations actually had an impact.

The test works for cluster_size between 8k and 2M (for smaller
sizes, it fails because our allocation patterns are not contiguous
with small clusters - in part, the largest consecutive allocation
we tend to get is often bounded by the size covered by one L2
table).

Note that testing for zero clusters is tricky: 'qemu-io map'
reports whether data comes from the current layer of the image
(useful for sniffing out which regions of the file have
QCOW_OFLAG_ZERO) - but doesn't show which clusters have mappings;
while 'qemu-img map' sees "zero":true for both unallocated and
zero clusters for any qcow2 with no backing layer (so less useful
at detecting true zero clusters), but reliably shows mappings.
So we have to rely on both queries side-by-side at each point of
the test.

d9ca2214bd iotests: Improve _filter_qemu_img_map
Although _filter_qemu_img_map documents that it scrubs offsets, it
was only doing so for human mode.  Of the existing tests using the
filter (97, 122, 150, 154, 176), two of them are affected, but it
does not hurt the validity of the tests to not require particular
mappings (another test, 66, uses offsets but intentionally does not
pass through _filter_qemu_img_map, because it checks that offsets
are unchanged before and after an operation).

Another justification for this patch is that it will allow a future
patch to utilize 'qemu-img map --output=json' to check the status of
preallocated zero clusters without regards to the mapping (since
the qcow2 mapping can be very sensitive to the chosen cluster size,
when preallocation is not in use).

fdfab37dfe qcow2: Make distinction between zero cluster types obvious
Treat plain zero clusters differently from allocated ones, so that
we can simplify the logic of checking whether an offset is present.
Do this by splitting QCOW2_CLUSTER_ZERO into two new enums,
QCOW2_CLUSTER_ZERO_PLAIN and QCOW2_CLUSTER_ZERO_ALLOC.

I tried to arrange the enum so that we could use
'ret <= QCOW2_CLUSTER_ZERO_PLAIN' for all unallocated types, and
'ret >= QCOW2_CLUSTER_ZERO_ALLOC' for allocated types, although
I didn't actually end up taking advantage of the layout.

In many cases, this leads to simpler code, by properly combining
cases (sometimes, both zero types pair together, other times,
plain zero is more like unallocated while allocated zero is more
like normal).

40812d9373 tests: Add coverage for recent block geometry fixes
Use blkdebug's new geometry constraints to emulate setups that
have needed past regression fixes: write zeroes asserting
when running through a loopback block device with max-transfer
smaller than cluster size, and discard rounding away portions
of requests not aligned to preferred boundaries.  Also, add
coverage that the block layer is honoring max transfer limits.

For now, a single iotest performs all actions, with the idea
that we can add future blkdebug constraint test cases in the
same file; but it can be split into multiple iotests if we find
reason to run one portion of the test in more setups than what
are possible in the other.

For reference, the final portion of the test (checking whether
discard passes as much as possible to the lowest layers of the
stack) works as follows:

qemu-io: discard 30M at 80000001, passed to blkdebug
  blkdebug: discard 511 bytes at 80000001, -ENOTSUP (smaller than
blkdebug's 512 align)
  blkdebug: discard 14371328 bytes at 80000512, passed to qcow2
    qcow2: discard 739840 bytes at 80000512, -ENOTSUP (smaller than
qcow2's 1M align)
    qcow2: discard 13M bytes at 77M, succeeds
  blkdebug: discard 15M bytes at 90M, passed to qcow2
    qcow2: discard 15M bytes at 90M, succeeds
  blkdebug: discard 1356800 bytes at 105M, passed to qcow2
    qcow2: discard 1M at 105M, succeeds
    qcow2: discard 308224 bytes at 106M, -ENOTSUP (smaller than qcow2's

6f3c90af3c qemu-io: Switch 'map' output to byte-based reporting
Mixing byte offset and sector allocation counts is a bit
confusing.  Also, reporting n/m sectors, where m decreases
according to the remaining size of the file, isn't really
adding any useful information; and reporting an offset at
both the front and end of the line, with large amounts of
whitespace, is pointless.  Update the output to use byte
counts and shorter lines, then adjust the affected tests
(./check -qcow2 102, ./check -vpc 146).

Note that 'qemu-io map' is MUCH weaker than 'qemu-img map';
the former only shows which regions of the active layer are
allocated, without regards to where the allocation comes from
or whether the allocated portion is known to read as zero
(because it is using the weaker bdrv_is_allocated()); while the
latter (especially in --output=json mode) reports more details
from bdrv_get_block_status().

aa93c834f9 iotests: Extend test 066
066 was supposed to be a test "for discarding preallocated zero
clusters", but it did so incompletely: While it did check the image
file's integrity after the operation, it did not confirm that the
clusters are indeed freed. This patch adds this test.

In addition, new cases for writing to preallocated zero clusters are
added.

bd269ebc82 sockets: Limit SocketAddressLegacy to external interfaces
SocketAddressLegacy is a simple union, and simple unions are awkward:
they have their variant members wrapped in a "data" object on the
wire, and require additional indirections in C.  SocketAddress is the
equivalent flat union.  Convert all users of SocketAddressLegacy to
SocketAddress, except for existing external interfaces.

5229564b83 test-qga: Actually test 0xff sync bytes
Commit 62c39b3 introduced test-qga, and at face value, appears
to be testing the 'guest-sync' behavior that is recommended for
guests in sending 0xff to QGA to force the parser to reset.  But
this aspect of the test has never actually done anything: the
qmp_fd() call chain converts its string argument into QObject,
then converts that QObject back to the actual string that is
sent over the wire - and the conversion process silently drops
the 0xff byte from the string sent to QGA, thus never resetting
the QGA parser.

An upcoming patch will get rid of the wasteful round trip
through QObject, at which point the string in test-qga will be
directly sent over the wire.

But fixing qmp_fd() to actually send 0xff over the wire is not
all we have to do - the actual QMP parser loudly complains that
0xff is not valid JSON, and sends an error message _prior_ to
actually parsing the 'guest-sync' or 'guest-sync-delimited'
command.  With 'guest-sync', we cannot easily tell if this error
message is a result of our command - which is WHY we invented
the 'guest-sync-delimited' command.  So for the testsuite, fix
things to only check 0xff behavior on 'guest-sync-delimited',
and to loop until we've consumed all garbage prior to the
requested delimiter, which is compatible with the documented actions
that a real QGA client is supposed to do.

Ideally, we'd fix the QGA JSON parser to silently ignore 0xff
rather than sending an error message back, at which point we
could enhance this test for 'guest-sync' as well as for
'guest-sync-delimited'.  But for the sake of this patch, our
testing of 'guest-sync' is no worse than it was pre-patch,
because we have never been sending 0xff over the wire in the
first place.
