fsdev: rename virtio-9p-marshal.{c,h} to 9p-iov-marshal.{c,h}
And rename v9fs_marshal to v9fs_iov_marshal, v9fs_unmarshal to
v9fs_iov_unmarshal.
The rationale behind this change is that, this marshalling interface is
used both by virtio and proxy helper. Renaming files and functions to
reflect the true nature of this interface.
Xen transport is going to have its own marshalling interface.

sun4u: split NPT and INT_DIS accesses between timer and compare registers
Accesses to the timer register high bit should only set NPT, whilst accesses
to the timer compare register high bit should only set INT_DIS. This fixes
issues with the timer being unexpectedly disabled whilst trying to boot
FreeBSD SPARC64.

sun4u: split out NPT and INT_DIS into separate CPUTimer fields
Currently there is confusion between use of these bits for the timer and timer
compare registers (while they both have the same value, the behaviour is
different). Split into two separate CPUTimer fields so we can always reference
the correct value.

seabios: stop updating aml files
ACPI aml files traditionally have been managed in the seabios repo.
In qemu version 2.0 we've switched over to have qemu generate the
acpi tables and provide them to the firmware via fw_cfg.
The old aml files are still there and used for old machine types.
Well, actually the q35 file only, the piix4 version is compiled into
seabios (unless built with CONFIG_ACPI_DSDT=n) and is there for
reference only.
The aml files havn't been touched for a long time, and given that
new features requiring acpi changes are typically only added to new
machine types this is unlikely to change in the future. So stop
updating them.
That allows to cleanup things a bit on the seabios side in the future.

io: fix stack allocation when sending of file descriptors
When sending file descriptors over a socket, we have to
allocate a data buffer to hold the FDs in the scmsghdr.
Unfortunately we allocated the buffer on the stack inside
an if () {} block, but called sendmsg() outside the block.
So the stack bytes holding the FDs were liable to be
overwritten with other data. By luck this was not a problem
when sending 1 FD, but if sending 2 or more then it would
fail.
The fix is to simply move the variables outside the nested
'if' block. To keep valgrind quiet we also zero-initialize
the 'control' buffer.

Currently AML API doesn't compose terms in form of
following pattern:
Opcode Arg2 Arg2 [Dst]
but ASL used in piix4/q35 DSDT ACPI tables uses that
form, so for clean conversion of it, AML API should
be able to handle an optional 'Dst' argumet used there.
Since above pattern is used by arithmetic/bit ops,
introduce helper that they could reuse.
It reduces code duplication in existing 5 aml_foo()
