ae23f78646 block: Add bdrv_supports_compressed_writes()
Filters cannot compress data themselves but they have to implement
.bdrv_co_pwritev_compressed() still (or they cannot forward compressed
writes).  Therefore, checking whether
bs->drv->bdrv_co_pwritev_compressed is non-NULL is not sufficient to
know whether the node can actually handle compressed writes.  This
function looks down the filter chain to see whether there is a
non-filter that can actually convert the compressed writes into
compressed data (and thus normal writes).

8b8277cdb0 block: Drop bdrv_is_encrypted()
The original purpose of bdrv_is_encrypted() was to inquire whether a BDS
can be used without the user entering a password or not.  It has not
been used for that purpose for quite some time.

Actually, it is not even fit for that purpose, because to answer that
question, it would have recursively query all of the given node's
children.

So now we have to decide in which direction we want to fix
bdrv_is_encrypted(): Recursively query all children, or drop it and just
use bs->encrypted to get the current node's status?

Nowadays, its only purpose is to report through bdrv_query_image_info()
whether the given image is encrypted or not.  For this purpose, it is
probably more interesting to see whether a given node itself is
encrypted or not (otherwise, a management application cannot discern for
certain which nodes are really encrypted and which just have encrypted
children).

7b99a26600 block: Include filters when freezing backing chain
In order to make filters work in backing chains, the associated
functions must be able to deal with them and freeze both COW and filter
child links.

While at it, add some comments that note which functions require their
caller to ensure that a given child link is not frozen, and how the
callers do so.

9ee413cb56 block: bdrv_set_backing_hd() is about bs->backing
bdrv_set_backing_hd() is a function that explicitly cares about the
bs->backing child.  Highlight that in its description and use
child_bs(bs->backing) instead of backing_bs(bs) to make it more obvious.

9a6fc88799 block: Add child access functions
There are BDS children that the general block layer code can access,
namely bs->file and bs->backing.  Since the introduction of filters and
external data files, their meaning is not quite clear.  bs->backing can
be a COW source, or it can be a filtered child; bs->file can be a
filtered child, it can be data and metadata storage, or it can be just
metadata storage.

This overloading really is not helpful.  This patch adds functions that
retrieve the correct child for each exact purpose.  Later patches in
this series will make use of them.  Doing so will allow us to handle
filter nodes in a meaningful way.

qemu_try_blockalign() is a generic API that call back to the
block driver to return its page alignment. As we call from
within the very same driver, we already know to page alignment
stored in our state. Remove indirections and use the value from
BDRVNVMeState.
This change is required to later remove the BlockDriverState
argument, to make nvme_init_queue() per hardware, and not per
block driver.

975a7bd228 block: Raise an error when backing file parameter is an empty string
Providing an empty string for the backing file parameter like so:

	qemu-img create -f qcow2 -b '' /tmp/foo

allows the flow of control to reach and subsequently fail an assert
statement because passing an empty string to

	bdrv_get_full_backing_filename_from_filename()

simply results in NULL being returned without an error being raised.

To fix this, let's check for an empty string when getting the value from
the opts list.

dc26435edb ui/gtk: Update refresh interval after widget is realized
Nikola reported on Windows when gd_vc_gfx_init() is called, the
window is not yet realized, so we run gd_refresh_rate_millihz(NULL)
which returns 0 milli-Hertz.
When a Widget is realized, it fires a 'realized' event. We already
have the gd_draw_event() handler registered for this even, so simply
move the gd_refresh_rate_millihz() there. When the event fires, the
window is known to exist.
This completes commit c4c00922cc original intention.

5b57a87e4e ui: Add more mouse buttons to SPICE
Add support for SIDE and EXTRA buttons.

The constants for buttons in both SPICE and QEMU are defined as
  LEFT
  MIDDLE
  RIGHT
  UP
  DOWN
  SIDE
  EXTRA
(same order).

"button_mask" contains for each bit the state of a button. Qemu currently
uses bits 0, 1, 2 respectively as LEFT, RIGHT, MIDDLE; also add bits 4
and 5 as UP and DOWN (using wheel movements). SPICE protocol uses
a bitmask based on the order above where LEFT is bit 0, MIDDLE is
bit 1 and so on till EXTRA being bit 6. To avoid clash with Qemu usage
SPICE bitmask from SIDE are move a bit more resulting respectively
in 0x40 and 0x80 values.

e7e8f33fb6 tcg: Fix tcg gen for vectorized absolute value
The fallback inline expansion for vectorized absolute value,
when the host doesn't support such an insn was flawed.

E.g. when a vector of bytes has all elements negative, mask
will be 0xffff_ffff_ffff_ffff.  Subtracting mask only adds 1
to the low element instead of all elements becase -mask is 1
and not 0x0101_0101_0101_0101.

6b8b622e87 cputlb: Make store_helper less fragile to compiler optimizations
This has no functional change.

The current function structure is:

    inline QEMU_ALWAYSINLINE
    store_memop() {
        switch () {
            ...
        default:
            qemu_build_not_reached();
        }
    }
    inline QEMU_ALWAYSINLINE
    store_helper() {
        ...
        if (span_two_pages_or_io) {
            ...
            helper_ret_stb_mmu();
        }
        store_memop();
    }
    helper_ret_stb_mmu() {
        store_helper();
    }

Whereas GCC will generate an error at compile-time when an always_inline
function is not inlined, Clang does not.  Nor does Clang prioritize the
inlining of always_inline functions.  Both of these are arguably bugs.

Both `store_memop` and `store_helper` need to be inlined and allow
constant propogations to eliminate the `qemu_build_not_reached` call.

However, if the compiler instead chooses to inline helper_ret_stb_mmu
into store_helper, then store_helper is now self-recursive and the
compiler is no longer able to propagate the constant in the same way.

This does not produce at current QEMU head, but was reproducible
at v4.2.0 with `clang-10 -O2 -fexperimental-new-pass-manager`.

The inline recursion problem can be fixed solely by marking
helper_ret_stb_mmu as noinline, so the compiler does not make an
incorrect decision about which functions to inline.

In addition, extract store_helper_unaligned as a noinline subroutine
that can be shared by all of the helpers.  This saves about 6k code
size in an optimized x86_64 build.

The default expiration time for artifacts seems to be very high (30 days?).
Since we only need the artifacts to pass the binaries from one stage to
the next one, we can decrease the expiration time to avoid to spam the
file server too much. Two days should be enough in case someone still wants
to have a look after the pipeline finished.

a7524adb41 gitlab/travis: Rework the disabled features tests
Let's focus on the gitlab-ci when testing the compilation with disabled
features, thus add more switches there (and while we're at it, sort them
also alphabetically). This should cover the test from the Travis CI now,
too, so that we can remove the now-redundant job from the Travis CI.

3bc1b8ee8c libqtest: Rename qmp_assert_error_class() to qmp_expect_error_and_unref()
qmp_assert_error_class() does more than just assert: it also unrefs
the @rsp argument.  Rename to qmp_expect_error_and_unref() to reduce
confusion.

  >>>     CID 1432368:  Incorrect expression  (ASSERT_SIDE_EFFECT)
  >>>     Argument "--count" of g_assert() has a side effect.  The containing function might work differently in a non-debug build.

ed943cc934 tests/qtest/tpm: Declare input buffers const and static
The functions using these arrays expect a "const unsigned char *"
argument, it is safe to declare these as 'static const'.

853b4baf30 configure: Add system = 'linux' for meson when cross-compiling
Meson needs the "system = xyz" line when cross-compiling. We are already
adding a "system = 'windows'" for the MinGW cross-compilation case here,
so let's add a "system = 'linux'" now for Linux hosts, too.
