It turns out that some hosts have a default malloc alignment less
than that required for vectors.
We assume that, with compiler annotation on CPUArchState, that we
can properly align the vector portion of the guest state. Fix the
alignment of the allocation by using qemu_memalloc when required.

object_property_get_bool()'s contract claims it returns NULL on error.
Pasto; it returns false.
object_property_get_int()'s contract claims it returns "negative". It
actually returns -1. All the other object_property_get_FOO()
contracts specify the exact error value, so do the same here.

object_property_get_enum() is the only object_property_FOO() that is
documented to return an undefined value on error. It does no such
thing, actually: it returns 0 on some errors, and -1 on others.
Needlessly complicated. Always return -1 on error, and adjust the
contract.

Some typedefs and macros are defined after the type check macros.
This makes it difficult to automatically replace their
definitions with OBJECT_DECLARE_TYPE.
Patch generated using:
$ ./scripts/codeconverter/converter.py -i \
--pattern=QOMStructTypedefSplit $(git grep -l '' -- '*.[ch]')
which will split "typdef struct { ... } TypedefName"
declarations.
Followed by:
$ ./scripts/codeconverter/converter.py -i --pattern=MoveSymbols \
$(git grep -l '' -- '*.[ch]')
which will:
- move the typedefs and #defines above the type check macros
- add missing #include "qom/object.h" lines if necessary

The documentation on g_byte_array_free()
<https://developer.gnome.org/glib/stable/glib-Byte-Arrays.html#g-byte-array-free>
says:
> Returns
>
> the element data if free_segment is FALSE, otherwise NULL. The element
> data should be freed using g_free().
Because we currently call g_byte_array_free() with free_segment=TRUE, we
end up passing data=NULL to fw_cfg_add_file().
On the plus side, fw_cfg_data_read() and fw_cfg_dma_transfer() both deal
with NULL data gracefully: QEMU does not crash when the guest reads such
an item, the guest just gets a properly sized, but zero-filled blob.
However, the bug breaks UEFI HTTPS boot, as the IANA_TLS_CIPHER array,
generated otherwise correctly by the "tls-cipher-suites" object, is in
effect replaced with a zero blob.
Fix the issue by passing free_segment=FALSE to g_byte_array_free():
- the caller (fw_cfg_add_from_generator()) temporarily assumes ownership
of the generated byte array,
- then ownership of the byte array is transfered to fw_cfg, as
fw_cfg_add_file() links (not copies) "data" into fw_cfg.

Aspeed have released an updated datasheet (v7) containing the silicon id
for the AST2600 A2. It looks like this:
SCU004 SCU014
AST2600-A0 0x05000303 0x05000303
AST2600-A1 0x05010303 0x05010303
AST2600-A2 0x05010303 0x05020303
AST2620-A1 0x05010203 0x05010203
AST2620-A2 0x05010203 0x05020203
The SCU004 (silicon id 1) value matches SCU014 for A0, but for
subsequent revisions it is hard coded to the A1 value.
Qemu effectively dropped support for the A0 in 7582591ae7 ("aspeed:
Support AST2600A1 silicon revision") as the A0 reset table was removed,
so it makes sense to only support the behaviour of A1 and onwards.

All it does is logging a performance warning on host side (once) in

Currently at startup if using cache=none on a filesystem lacking
O_DIRECT such as tmpfs, at startup QEMU prints
qemu-system-x86_64: -drive file=/tmp/foo.img,cache=none: file system may not support O_DIRECT
qemu-system-x86_64: -drive file=/tmp/foo.img,cache=none: Could not open '/tmp/foo.img': Invalid argument
while at QMP level the hint is missing, so QEMU reports just
"error": {
"class": "GenericError",
"desc": "Could not open '/tmp/foo.img': Invalid argument"
}
which is close to useless for the end user trying to figure out what
they did wrong.
With this change at startup QEMU prints
qemu-system-x86_64: -drive file=/tmp/foo.img,cache=none: Unable to open '/tmp/foo.img': filesystem does not support O_DIRECT
while at the QMP level QEMU reports a massively more informative
"error": {
"class": "GenericError",
"desc": "Unable to open '/tmp/foo.img': filesystem does not support O_DIRECT"
}
