Since commit 578f3c7b08 ("arm: add fw_cfg to "virt" board",
2014-12-22), the machvirt_init() unconditionally creates the
fw_cfg object. Later, commit c30e15658b ("smbios: implement
smbios support for mach-virt", 2015-09-07) added a superfluous
null-check on it.
Remove this superfluous check.

The 'boot_splash_filedata_size' was introduced as a global variable
in 3d3b8303c6. This variable is used as a 'size' argument to the
fw_cfg_add_file(). This function has an interface contract with its
'data' argument, but there is no such contract for 'size' (this is
not a referenced pointer). We can simply remove it.

Currently any client which can complete the TLS handshake is able to use
a chardev server. The server admin can turn on the 'verify-peer' option
for the x509 creds to require the client to provide a x509
certificate. This means the client will have to acquire a certificate
from the CA before they are permitted to use the chardev server. This is
still a fairly low bar.
This adds a 'tls-authz=OBJECT-ID' option to the socket chardev backend
which takes the ID of a previously added 'QAuthZ' object instance. This
will be used to validate the client's x509 distinguished name. Clients
failing the check will not be permitted to use the chardev server.
For example to setup authorization that only allows connection from a
client whose x509 certificate distinguished name contains 'CN=fred', you
would use:
$QEMU -object tls-creds-x509,id=tls0,dir=/home/berrange/qemutls,\
endpoint=server,verify-peer=yes \
-object authz-simple,id=authz0,identity=CN=laptop.example.com,,\
O=Example Org,,L=London,,ST=London,,C=GB \
-chardev socket,host=127.0.0.1,port=9000,server,\

flatview_add_to_dispatch() registers page based on the condition of
*section*, which may looks like this:
|s|PPPPPPP|s|
where s stands for subpage and P for page.
The procedure of this function could be described as:
- register first subpage
- register page
- register last subpage
This means the procedure could be simplified into these three steps
instead of a loop iteration.
This patch refactors the function into three corresponding steps and
adds some comment to clarify it.

Previous to OpenBSD 6.3 [1], fcntl(F_SETFL) is not permitted on
memory devices.
Trying this call sets errno to ENODEV ("not a memory device"):
19 ENODEV Operation not supported by device.
An attempt was made to apply an inappropriate function to a device,
for example, trying to read a write-only device such as a printer.
Do not assert fcntl failures in this specific case (errno set to ENODEV)
on OpenBSD. This fixes:
$ lm32-softmmu/qemu-system-lm32
assertion "f != -1" failed: file "util/oslib-posix.c", line 247, function "qemu_set_nonblock"

[1] The fix seems https://github.com/openbsd/src/commit/c2a35b387f9d3c
"fcntl(F_SETFL) invokes the FIONBIO and FIOASYNC ioctls internally, so
the memory devices (/dev/null, /dev/zero, etc) need to permit them."

All the fields in struct virtio_scsi_ctrl_tmf_req are naturally aligned,
so we could in theory drop QEMU_PACKED. Unfortunately, the header file
