block: Let format drivers pass @exact
When truncating a format node, the @exact parameter is generally handled
simply by virtue of the format storing the new size in the image
metadata. Such formats do not need to pass on the parameter to their
file nodes.
There are exceptions, though:
- raw and crypto cannot store the image size, and thus must pass on
@exact.
- When using qcow2 with an external data file, it just makes sense to
keep its size in sync with the qcow2 virtual disk (because the
external data file is the virtual disk). Therefore, we should pass
@exact when truncating it.

Currently total allocation for parallel requests to block-copy instance
is unlimited. Let's limit it to 128 MiB.
For now block-copy is used only in backup, so actually we limit total

Introduce an API for some shared splittable resource, like memory.
It's going to be used by backup. Backup uses both read/write io and
copy_range. copy_range may consume memory implictly, so the new API is
abstract: it doesn't allocate any real memory but only hands out
tickets.
The idea is that we have some total amount of something and callers
should wait in coroutine queue if there is not enough of the resource
at the moment.

Merge copying code into one function block_copy_do_copy, which only
calls bdrv_ io functions and don't do any synchronization (like dirty
bitmap set/reset).
Refactor block_copy() function so that it takes full decision about
size of chunk to be copied and does all the synchronization (checking
intersecting requests, set/reset dirty bitmaps).
It will help:
- introduce parallel processing of block_copy iterations: we need to
calculate chunk size, start async chunk copying and go to the next
iteration
- simplify synchronization improvement (like memory limiting in
further commit and reducing critical section (now we lock the whole
requested range, when actually we need to lock only dirty region
which we handle at the moment))

Large copy range may imply memory allocation and large io effort, so
using 2G copy range request may be bad idea. Let's limit it to 16 MiB.
It also helps the following patch to refactor copy-with-offload

Note, that total memory usage of backup is still not limited, it will

block/block-copy: allocate buffer in block_copy_with_bounce_buffer
Move bounce_buffer allocation block_copy_with_bounce_buffer. This
commit simplifies further work on implementing copying by larger chunks
(of different size) and further asynchronous handling of block_copy
iterations (with help of block/aio_task API).
Allocation works fast, a lot faster than disk io, so it's not a problem
that we now allocate/free bounce_buffer more times. And we anyway will
have to allocate several bounce_buffers for parallel execution of loop
iterations in future.

iotests: Introduce $SOCK_DIR
Unix sockets generally have a maximum path length. Depending on your
$TEST_DIR, it may be exceeded and then all tests that create and use
Unix sockets there may fail.
Circumvent this by adding a new scratch directory specifically for
Unix socket files. It defaults to a temporary directory (mktemp -d)
that is completely removed after the iotests are done.
(By default, mktemp -d creates a /tmp/tmp.XXXXXXXXXX directory, which
should be short enough for our use cases.)
Use mkdir -p to create the directory (because it seems right), and do
the same for $TEST_DIR (because there is no reason for that to be
created in any different way).

block/mirror: support unaligned write in active mirror
Prior 9adc1cb49af8d do_sync_target_write had a bug: it reset aligned-up
region in the dirty bitmap, which means that we may not copy some bytes
and assume them copied, which actually leads to producing corrupted
target.
So 9adc1cb49af8d forced dirty bitmap granularity to be
request_alignment for mirror-top filter, so we are not working with
unaligned requests. However forcing large alignment obviously decreases
performance of unaligned requests.
This commit provides another solution for the problem: if unaligned
padding is already dirty, we can safely ignore it, as
1. It's dirty, it will be copied by mirror_iteration anyway
2. It's dirty, so skipping it now we don't increase dirtiness of the
bitmap and therefore don't damage "synchronicity" of the
write-blocking mirror.
If unaligned padding is not dirty, we just write it, no reason to touch
dirty bitmap if we succeed (on failure we'll set the whole region
ofcourse, but we loss "synchronicity" on failure anyway).
Note: we need to disable dirty_bitmap, otherwise we will not be able to
see in do_sync_target_write bitmap state before current operation. We
may of course check dirty bitmap before the operation in
bdrv_mirror_top_do_write and remember it, but we don't need active
dirty bitmap for write-blocking mirror anyway.
New code-path is unused until the following commit reverts 9adc1cb49af8d.

iotests: Allow skipping test cases
case_notrun() does not actually skip the current test case. It just
adds a "notrun" note and then returns to the caller, who manually has to
skip the test. Generally, skipping a test case is as simple as
returning from the current function, but not always: For example, this
model does not allow skipping tests already in the setUp() function.
Thus, add a QMPTestCase.case_skip() function that invokes case_notrun()
and then self.skipTest(). To make this work, we need to filter the

Add a job to generate the release tarball and build/install few
QEMU targets from it.
Ideally we should build the 'efi' target from the 'roms' directory,
but it is too time consuming.
This job is only triggered when a tag starting with 'v' is pushed,
which is the case with release candidate tags.
