d852535859 plugins/howvec: adapting to the new argument passing scheme
Correctly parsing plugin argument since they now must be provided as
full-form boolean parameters, e.g.:
    -plugin ./contrib/plugins/libhowvec.so,verbose=on,inline=on

Also, introduced the argument "count" that accepts one opt to count
individually at a time.

60753843f6 plugins/hwprofile: adapt to the new plugin arguments scheme
Parsing boolean arguments correctly (e.g. pattern=on or source=false).
Introduced a new "track" argument that takes a [read|write] value. This
substitutes passing read or write to "arg=" that is deprecated.

Also, matches are now taken one by one through the "match" argument.

f698d5ef1c plugins/hotpages: introduce sortby arg and parsed bool args correctly
Since plugin arguments now expect boolean arguments, a plugin argument
name "sortby" now expects a value of "read", "write", or "address".

"io" arg is now expected to be passed as a full-form boolean parameter,
i.e. "io=on|true|yes|off|false|no"

3a445acb49 plugins: allow plugin arguments to be passed directly
Passing arguments to plugins had to be done through "arg=<argname>".
This is redundant and introduces confusion especially when the argument
has a name and value (e.g. `-plugin plugin_name,arg="argname=argvalue"`).

This allows passing plugin arguments directly e.g:

    `-plugin plugin_name,argname=argvalue`

For now, passing arguments through "arg=" is still supports but outputs
a deprecation warning.

Also, this commit makes boolean arguments passed to plugins in the
`argname=on|off` form instead of the deprecated short-boolean form.

c79a2116af plugins/cache: supported multicore cache modelling
Multicore L1 cache modelling is introduced and is supported for both
full system emulation and linux-user.

For full-system emulation, L1 icache and dcache are maintained for each
available core, since this information is exposed to the plugin through
`qemu_plugin_n_vcpus()`.

For linux-user, a static number of cores is assumed (default 1 core, and
can be provided as a plugin argument `cores=N`). Every memory access
goes through one of these caches, this approach is taken as it's
somewhat akin to what happens on real setup, where a program that
dispatches more threads than the available cores, they'll thrash
each other

b906acace2 plugins: do not limit exported symbols if modules are active
On Mac --enable-modules and --enable-plugins are currently incompatible, because the
Apple -Wl,-exported_symbols_list command line options prevents the export of any
symbols needed by the modules.  On x86 -Wl,--dynamic-list does not have this effect,
but only because the -Wl,--export-dynamic option provided by gmodule-2.0.pc overrides
it.  On Apple there is no -Wl,--export-dynamic, because it is the default, and thus
no override.

Either way, when modules are active there is no reason to include the plugin_ldflags.
While at it, avoid the useless -Wl,--export-dynamic when --enable-plugins is
specified but --enable-modules is not; this way, the GNU and Apple configurations
are more similar.

40e916b4bc gitlab-ci: Fix ..._RUNNER_AVAILABLE variables and document them
The patch that recently introduced the S390X_RUNNER_AVAILABLE variable
in custom-runners.yml missed that the bottom half of the file is rather
about aarch64 than s390x. Thus rename the S390X_RUNNER_AVAILABLE to
AARCH64_RUNNER_AVAILABLE in those jobs.

Finally mention both variables in our CI documentation, too.

8d316275ad gitlab-ci: Merge "build-disabled" with "build-without-default-features"
Both jobs are testing more or less the same thing (building QEMU with
features disabled), so we are wasting precious CI cycles here by doing
this twice. Merge the jobs by using --without-default-features by default
and just adding some additional --disable-... switches which are not
covered by the generic switch (yet). And while we're at it, also test
compilation with "--disable-fdt" (which forces us to change the list
of targets in this job, though, since some targets do not work without
fdt).

66b63809fa iotests/image-fleecing: rename tgt_node
Actually target of backup(sync=None) is not a final backup target:
image fleecing is intended to be used with external tool, which will
copy data from fleecing node to some real backup target.

Also, we are going to add a test case for "push backup with fleecing",
where instead of exporting fleecing node by NBD, we'll start a backup
job from fleecing node to real backup target.

To avoid confusion, let's rename temporary fleecing node now.

To achieve this:

 - cbw_init gets unused flags argument and becomes cbw_open
 - block_copy_state_free() call moved to new cbw_close()
 - in bdrv_cbw_append:
   - options are completed with driver and node-name, and we can simply
     use bdrv_insert_node() to do both open and drained replacing
 - in bdrv_cbw_drop:
   - cbw_close() is now responsible for freeing s->bcs, so don't do it

We are going to publish copy-before-write filter. So, user should be
able to create it with blockdev-add first, specifying both filtered and
target children. And then do blockdev-reopen, to actually insert the
filter where needed.

Currently, filter unshares write permission unconditionally on source
node. It's good, but it will not allow to do blockdev-add. So, let's
relax restrictions when filter doesn't have any parent.

Test output is modified, as now permission conflict happens only when
job creates a blk parent for filter node.

aaa94a1b3c fuzz: unblock SIGALRM so the timeout works
The timeout mechanism won't work if SIGALRM is blocked. This changes
unmasks SIGALRM when the timer is installed. This doesn't completely
solve the problem, as the fuzzer could trigger some device activity that
re-masks SIGALRM. However, there are currently no inputs on OSS-Fuzz
that re-mask SIGALRM and timeout. If that turns out to be a real issue,
we could try to hook sigmask-type calls, or use a separate timer thread.
