'event-loop-base' provides basic property handling for all 'AioContext'
based event loops. So let's define a new 'MainLoopClass' that inherits
from it. This will permit tweaking the main loop's properties through
qapi as well as through the command line using the '-object' keyword[1].
Only one instance of 'MainLoopClass' might be created at any time.
'EventLoopBaseClass' learns a new callback, 'can_be_deleted()' so as to
mark 'MainLoop' as non-deletable.
[1] For example:
-object main-loop,id=main-loop,aio-max-batch=<value>

Introduce the 'event-loop-base' abstract class, it'll hold the
properties common to all event loops and provide the necessary hooks for
their creation and maintenance. Then have iothread inherit from it.
EventLoopBaseClass is defined as user creatable and provides a hook for
its children to attach themselves to the user creatable class 'complete'
function. It also provides an update_params() callback to propagate
property changes onto its children.
The new 'event-loop-base' class will live in the root directory. It is
built on its own using the 'link_whole' option (there are no direct
function dependencies between the class and its children, it all happens
trough 'constructor' magic). And also imposes new compilation
dependencies:
qom <- event-loop-base <- blockdev (iothread.c)
And in subsequent patches:
qom <- event-loop-base <- qemuutil (util/main-loop.c)
All this forced some amount of reordering in meson.build:
- Moved qom build definition before qemuutil. Doing it the other way
around (i.e. moving qemuutil after qom) isn't possible as a lot of
core libraries that live in between the two depend on it.
- Process the 'hw' subdir earlier, as it introduces files into the
'qom' source set.
No functional changes intended.

Currently, commands-posix.c assumes that getifaddrs() is only
available on Linux, and so the related guest agent command
guest-network-get-interfaces is only implemented for #ifdef __linux__.
This function does exist on other platforms, though, such as Solaris.
So, add a meson check for getifaddrs(), and move the code for
guest-network-get-interfaces to be built whenever getifaddrs() is
available.
The implementation for guest-network-get-interfaces still has some
Linux-specific code, which is not fixed in this commit. This commit
moves the relevant big chunks of code around without changing them, so
a future commit can change the code in place.

An alternative way is to use sem_trywait + usleep, maybe we can

So maybe remove the usage of POSIX semaphore and turn to use the

If there is a failing iotest, the output is currently not logged to

due to a current meson bug that will be fixed here:
https://github.com/mesonbuild/meson/commit/c3f145ca2b9f5.patch ).
We could update the "meson test" call in tests/Makefile.include,
but actually it's nicer and easier if we simply do not treat the
iotests as separate test target anymore and integrate them along
with the other test suites. This has the disadvantage of not getting
the detailed progress indication there anymore, but since that was
only working right in single-threaded "make -j1" mode anyway, it's
not a huge loss right now.

On older Solaris releases (before Solaris 11), we didn't get a
prototype for madvise, and so util/osdep.c provides its own prototype.
Some time between the public Solaris 11.4 release and Solaris 11.4.42
CBE, we started getting an madvise prototype that looks like this:
extern int madvise(void *, size_t, int);
which conflicts with the prototype in util/osdeps.c. Instead of always
declaring this prototype, check if we're missing the madvise()
prototype, and only declare it ourselves if the prototype is missing.
Move the prototype to include/qemu/osdep.h, the normal place to handle
platform-specific header quirks.
The 'missing_madvise_proto' meson check contains an obviously wrong
prototype for madvise. So if that code compiles and links, we must be
missing the actual prototype for madvise.
