eepro100: Update ROM file support
Use new way to associate ROM files to devices.
Currently, there is only a ROM file for i82559er
included in QEMU, so the patch does not add
.romfile for the other devices.
When flexible mode is fixed in eepro100, adding
more ROM files will be possible. It should be
possible to create them from pxe-i82559er.bin,
because etherboot uses the same driver for all
eepro100 devices (only PCI ids differ).
Maybe it is even possible to create a single
pxe-i8255x.bin which supports all eepro100 devices
(not supported with current etherboot).

kvm: Detect availability of kvm_para.h
Will be required for upcoming KVM cpuid leaf. Host kernels >= 2.6.32 as
well as future kvm-kmod releases (more recent than kvm-kmod-2.6.32.3)
do/will provide them.
The 32-bit right-shift instructions is defined to extend the shifted
output to 64-bits. A shift count of zero therefore is a simple
extension without actually shifting.
The {div,divu}2 opcodes are intended for systems for which the
division instruction produces both quotient and remainder. Sparc
is not such a system. Indeed, the remainder must be computed as
quot = a / b
rem = a - (quot * b)
Split out a tcg_out_div32 function that properly initializes Y
with the extension of the input to 64-bits. Discard the code
that used the 64-bit DIVX on sparc9/sparcv8plus without extending
the inputs to 64-bits. Implement remainders in terms of division
followed by multiplication.
Add a function to handle the register-vs-immediate test for arithmetic.
Also, adjust the OP_32_64 macro so that it auto-indents properly.
Rename the gen_arith32 label to gen_arith, since it handles 64-bit
arithmetic as well.

Handle TFTP ERROR from client
If a PXE client only wants to find out the size of a file, it will
open the file and then abort the transfer by sending a TFTP ERROR packet.
The ERROR packet should cause qemu to terminate the session. If not,
the sessions will soon run out and cause timeouts in the client.
Also, if a TFTP session already exists with same IP/UDP port, it
should be terminated when a new RRQ is received, instead of creating a
duplicate (which will never be used).
A patch for gPXE to send the ERROR packet is also being submitted to
gPXE. Together they resolve slowness/hanging when booting pxegrub from
qemu's internal TFTP server. The patch from Milan Plzik to return
after sending OACK is also required for a complete fix.
Currently the dmg image format driver simply opens the images as raw
if any kind of failure happens. This is contrarty to the behaviour
of all other image formats which just return an error and let the
block core deal with it.
Since patch ed757e140c0ada220f213036e4497315d24ca8bct, virtio will
sometimes clear all status registers on bus master disable, which loses
information such as VIRTIO_CONFIG_S_FAILED bit. This is a result of
a patch being misapplied: code uses ! instead of ~ for bit
operations as in Yan's original patch. This obviously does not make
sense.
Add feature bits as properties to virtio. This makes it possible to e.g. define
machine without indirect buffer support, which is required for 0.10
compatibility, or without hardware checksum support, which is required for 0.11
compatibility. Since default values for optional features are now set by qdev,
get_features callback has been modified: it sets non-optional bits, and clears
bits not supported by host.
This adds "bit" property type, which is a boolean stored in a 32 bit
integer field, with legal values on and off. Will be used by virtio for
feature bits.

debugcon: support for debugging consoles (e.g. Bochs port 0xe9)
Add generic support for debugging consoles (simple I/O ports which
when written to cause debugging output to be written to a target.)
The current implementation matches Bochs' port 0xe9, allowing the same
debugging code to be used for both Bochs and Qemu.
There is no vm state associated with the debugging port, simply
because it has none -- the entire interface is a single, stateless,
write-only port.
Most of the code was cribbed from the serial port driver.
v2: removed non-ISA variants (they can be introduced when/if someone
wants them, using code from the serial port); added configurable
readback (Bochs returns 0xe9 on a read from this register, mimic that
by default) This retains the apparently somewhat controversial user
friendly option, however.
v3: reimplemented the user friendly option as a synthetic option
("-debugcon foo" basically ends up being a parser-level shorthand for
"-chardev stdio,id=debugcon -device isa-debugcon,chardev=debugcon") --
this dramatically reduced the complexity while keeping the same level
of user friendliness.
