osdep: set _FORTIFY_SOURCE=2 when optimization is enabled

Currently we set _FORTIFY_SOURCE=2 as a compiler argument when the
meson 'optimization' setting is non-zero, the compiler is GCC and
the target is Linux.

While the default QEMU optimization level is 2, user could override
this by setting CFLAGS="-O0" or --extra-cflags="-O0" when running
configure and this won't be reflected in the meson 'optimization'
setting. As a result we try to enable _FORTIFY_SOURCE=2 and then the
user gets compile errors as it only works with optimization.

Rather than trying to improve detection in meson, it is simpler to
just check the __OPTIMIZE__ define from osdep.h.

The comment about being incompatible with clang appears to be
outdated, as compilation works fine without excluding clang.

In the coroutine code we must set _FORTIFY_SOURCE=0 to stop the
logic in osdep.h then enabling it.

qobject atomics osdep: Make a few macros more hygienic

Variables declared in macros can shadow other variables. Much of the
time, this is harmless, e.g.:

#define _FDT(exp) \
do { \
int ret = (exp); \
if (ret < 0) { \
error_report("error creating device tree: %s: %s", \
#exp, fdt_strerror(ret)); \
exit(1); \
} \
} while (0)

Harmless shadowing in h_client_architecture_support():

target_ulong ret;

[...]

ret = do_client_architecture_support(cpu, spapr, vec, fdt_bufsize);
if (ret == H_SUCCESS) {
_FDT((fdt_pack(spapr->fdt_blob)));
[...]
}

return ret;

However, we can get in trouble when the shadowed variable is used in a
macro argument:

#define QOBJECT(obj) ({ \
typeof(obj) o = (obj); \
o ? container_of(&(o)->base, QObject, base) : NULL; \
})

QOBJECT(o) expands into

({
---> typeof(o) o = (o);
o ? container_of(&(o)->base, QObject, base) : NULL;
})

Unintended variable name capture at --->. We'd be saved by
-Winit-self. But I could certainly construct more elaborate death
traps that don't trigger it.

To reduce the risk of trapping ourselves, we use variable names in
macros that no sane person would use elsewhere. Here's our actual
definition of QOBJECT():

#define QOBJECT(obj) ({ \
typeof(obj) _obj = (obj); \
_obj ? container_of(&(_obj)->base, QObject, base) : NULL; \
})

Works well enough until we nest macro calls. For instance, with

#define qobject_ref(obj) ({ \
typeof(obj) _obj = (obj); \
qobject_ref_impl(QOBJECT(_obj)); \
_obj; \
})

the expression qobject_ref(obj) expands into

({
typeof(obj) _obj = (obj);
qobject_ref_impl(
({
---> typeof(_obj) _obj = (_obj);
_obj ? container_of(&(_obj)->base, QObject, base) : NULL;
}));
_obj;
})

Unintended variable name capture at --->.

The only reliable way to prevent unintended variable name capture is
-Wshadow.

One blocker for enabling it is shadowing hiding in function-like
macros like

qdict_put(dict, "name", qobject_ref(...))

qdict_put() wraps its last argument in QOBJECT(), and the last
argument here contains another QOBJECT().

Use dark preprocessor sorcery to make the macros that give us this
problem use different variable names on every call.

block: Add no_coroutine_fn and coroutine_mixed_fn marker

Add more annotations to functions, describing valid and invalid
calls from coroutine to non-coroutine context.

When applied to a function, no_coroutine_fn advertises that it should
not be called from coroutine_fn functions. This can be because the
function blocks or, in the case of generated_co_wrapper, to enforce
that coroutine_fn functions directly call the coroutine_fn that backs
the generated_co_wrapper.

coroutine_mixed_fn instead is for function that can be called in
both coroutine and non-coroutine context, but will suspend when
called in coroutine context. Annotating them is a first step
towards enforcing that non-annotated functions are absolutely
not going to suspend.

These can be used for example with the vrc tool:

# find functions that *really* cannot be called from no_coroutine_fn
(vrc) load --loader clang libblock.fa.p/meson-generated_.._block_block-gen.c.o
(vrc) paths [no_coroutine_fn,!coroutine_mixed_fn]
bdrv_remove_persistent_dirty_bitmap
bdrv_create
bdrv_can_store_new_dirty_bitmap

# find how coroutine_fns end up calling a mixed function
(vrc) load --loader clang --force libblock.fa.p/*.c.o
(vrc) paths [coroutine_fn] [!no_coroutine_fn]* [coroutine_mixed_fn]

docs/about: Update the support statement for Windows

Our support statement for Windows currently talks about "Vista / Server
2008" - which is related to the API of Windows, and this is not easy
to understand for the non-technical users. Additionally, glib sets the
_WIN32_WINNT macro to 0x0601 already, which indicates the Windows 7 API,
so QEMU effectively depends on the Windows 7 API, too.

Thus let's bump the _WIN32_WINNT setting in QEMU to the same level as
glib uses and adjust our support statement in the documentation to
something similar that we're using for Linux and the *BSD systems
(i.e. only the two most recent versions), which should hopefully be
easier to understand for the users now.

And since we're nowadays also compile-testing QEMU with MSYS2 on Windows
itself, I think we could mention this build environment here, too.
