rtl8139: Fix invalid IO access alignment
This patch makes iPXE work with the rtl8139 emulation. The rtl8139
driver in iPXE issues a 16bit access on the ChipCmd register
(offset 0x37) to check the status of the rx buffer. The offset of the
ioport access was getting fixed up to 0x36 in qemu, causing the value
read in iPXE to be invalid.
This fixes an issue with iPXE reporting timeouts during TFTP transfers.
Reposting this here because it is trivial enough and the original post
on qemu-devel didn't attract much attention.
Also, the inw() which was causing the issue has been replaced with an
inb() in upstream iPXE:

block: allow migration to work with image files (v3)
Image files have two types of data: immutable data that describes things like
image size, backing files, etc. and mutable data that includes offset and
reference count tables.
Today, image formats aggressively cache mutable data to improve performance. In
some cases, this happens before a guest even starts. When dealing with live
migration, since a file is open on two machines, the caching of meta data can
lead to data corruption.
This patch addresses this by introducing a mechanism to invalidate any cached
mutable data a block driver may have which is then used by the live migration
code.
NB, this still requires coherent shared storage. Addressing migration without
coherent shared storage (i.e. NFS) requires additional work.

pseries: Fix qdev.id handling in the VIO bus code
When the user creates a device on the command line with -device, they
can specify the id, using id=foo. Currently the VIO bus code overwrites
this id with it's own value. We should only set qdev.id if it is not
already set by the user.
The device tree code uses qdev.id for the device tree node name, however
we can't rely on the user specifiying the id using proper device tree
syntax, ie. device@reg. So separate the device tree node name from the
qdev.id, but use the same syntax, so they will match by default.

pseries: Allow kernel's early debug output to work
The PAPR specification defines a virtual TTY/console interface for guest
OSes to use via the H_PUT_TERM_CHAR and H_GET_TERM_CHAR hypercalls. There
can be multiple virtual ttys, so these take a "termno" parameter. This
encodes which vty to use as the 'reg' property on the device tree node
associated with that vty.
However, with the early debug options enabled, the Linux kernel will
attempt debugging output through the vty very early, before it has read
the device tree. In this case it always uses a termno of 0. This works
on the existing PowerVM hypervisor, so we assume there must be a hack /
feature in there which interprets termno==0 to mean the default primary
console.
To help with debugging kernels, including existing distribution kernels,
this patch implements a similar feature / hack in qemu. If termno==0
is supplied to H_{GET,PUT}_TERM_CHAR, they use the first available vty
device instead.
We need to be careful in the case that the user has manually created
an spapr-vty at address 0. So first we search for the specified reg and
only if that doesn't match do we fall back.

If qemu is run like:
qemu-system-ppc64 -nodefaults -device spapr-vty
We end up in spapr_vty_init() with dev->chardev == NULL. Currently
that leads to a segfault because we unconditionally call
qemu_chr_add_handlers().
Although we could make that call conditional, I think a spapr-vty
without a chardev is basically useless so fail the init. This is
similar to what the serial code does for example.

pseries: Correct RAM size check for SLOF
The SLOF firmware used on the pseries machine needs a reasonable amount of
(guest) RAM in order to run, so we have a check in the machine init
function to check that this is available. However, SLOF runs in real mode
(MMU off) which means it can only actually access the RMA (Real Mode Area),
not all of RAM. In many cases the RMA is the same as all RAM, but when
running with Book3S HV KVM on PowerPC 970, the RMA must be especially
allocated to be (host) physically contiguous. In this case, the RMA size
is determined by what the host admin allocated at boot time, and will
usually be less than the whole guest RAM size.
This patch corrects the test to see if SLOF has enough memory for this
case.
In addition, more recent versions of SLOF that were committed earlier don't
need quite as much memory as earlier versions. Therefore, this patch also
reduces the amount of RAM we require to run SLOF.

scsi: fix parsing of allocation length field
- several MMC commands were parsed wrong by QEMU because their allocation
length/parameter list length is placed in a non-standard position in
the CDB (i.e. it is different from most commands with the same value in
bits 5-7).
- SEND VOLUME TAG length was multiplied by 40 which is not in SMC. The
parameter list length is between 32 and 40 bytes. Same for MEDIUM SCAN
(spec found at http://ldkelley.com/SCSI2/SCSI2-16.html but not in any of
the PDFs I have here).
- READ_POSITION (SSC) conflicts with PRE_FETCH (SBC). READ_POSITION's
transfer length is not hardcoded to 20 in SSC; for PRE_FETCH cmd->xfer
should be 0. Both fixed.
- FORMAT MEDIUM (the SSC name for FORMAT UNIT) was missing. The FORMAT
UNIT command is still somewhat broken for block devices because its
parameter list length is not in the CDB. However it works for CD/DVD
drives, which mandate the length of the payload.
- fixed wrong sign-extensions for 32-bit fields (for the LBA field,
this affects disks >1 TB).
- several other SBC or SSC commands were missing or parsed wrong.
