Make stdvga provide the new vgabios binary (with pcibios support)
using the PCI option rom bar. Seabios will happily load it from
there. The new vga bios will also lookup the framebuffer address
in pci config space, so the magic bochs lfb @ 0xe0000000 is not
needed any more -> zap it.
Without the patch:
# dmesg | grep framebuffer
vesafb: framebuffer at 0xe0000000, mapped to 0xf7e80000, using 1875k, total 8192k
# lspci -vs2

The HDA bus supports up to 15 codecs, with addresses 0 ... 14.
We get that wrong in two places:
* When handing out addresses we accept address 15 as valid.
* The bitmasks for two registers (WAKEEN and STATESTS) don't
have bit 14 set.
This patch fixes it.

This patch adds three devices to qemu:
intel-hda
Intel HD Audio Controller, the PCI device. Provides a HDA bus.
Emulates ICH6 at the moment. Adding a ICH9 PCIE
variant shouldn't be hard.
hda-duplex
HDA Codec. Attaches to the HDA bus. Supports 16bit stereo,
rates 16k -> 96k, playback, recording and volume control
(with CONFIG_MIXEMU=y).
hda-output
HDA Codec without recording support. Subset of the hda-duplex
codec. Use this if you don't want your guests access your mic.
Usage: add '-device intel-hda -device hda-duplex' to your command line.
Tested guests:
* Linux works.
* Win7 works.
* DOS (mpxplay) works.
* WinXP doesn't work.
[ v2 changes ]
* Fixed endianess, big endian hosts work now.
* Fixed some emulation bugs.
* Added immediate command emulation.
* Added vmstate support.
* Make it behave like all other sound card drivers:
- can be configured via '--audio-card-list=hda'
- can be added to a VM using '-soundhw hda'
* Code style fixups.
* Zapped guest-triggerable asserts.
* Handle partial reads/writes of audio data correctly.

Move timer init functions to a new file, qemu-timer-common.c. Make other
critical timer functions inlined to preserve performance in
qemu-timer.c, also move muldiv64() (used by the inline functions)
to qemu-timer.h.
Adjust block/raw-posix.c and simpletrace.c to use get_clock() directly.
Remove a similar/duplicate definition in qemu-tool.c.
Adjust hw/omap_clk.c to include qemu-timer.h because muldiv64() is used
there.
After this change, tracing can be used also for user code and
simpletrace on Win32.

The werror option now affects not only write requests, but also flush requests.
Previously, it was not possible to stop a VM on a failed flush.
Signed-off-by: Kevin Wolf <kwolf@redhat.com>
Instead of always assuming success for bdrv_aio_flush, actually do something
with the error. This respects the werror option and accordingly ignores the
error, reports it to the guest or stops the VM and retries after cont.
Ignoring the error is trivial, obviously. For stopping the VM and retrying
later old code can be reused, but we need to introduce a new status for "retry
a flush". For reporting to the guest, fortunately the same action is required
as for a failed read/write (status = DRDY | ERR, error = ABRT), so this code
can be reused as well.

This patch updates the vmmouse handler registration and activation.
Old behavior:
vmmouse_read_id, vmmouse_request_relative and vmmouse_request_absolute
unregister the handler and re-register it.
New behavior:
vmmouse_request_relative and vmmouse_request_absolute will unregister
the handler in case the mode did change. Then register and active the
handler with current mode if needed.
Note that the old code never ever *activates* the handler, so the
vmmouse doesn't receive events. This trips up Fedora 14 for example:
Boot a default install without usb tablet, watch the X-Server activating
the vmmouse then, enjoy a non-functional mouse.

readv & writev, read & write respectively from the current offset
of the file & hence their use has to be preceeded by a call to lseek.
preadv/writev can be used instead, as they take the offset as an argument.
This saves one system call( lseek ).
In case preadv is not supported, it is implemented by an lseek
followed by a readv. Depending upon the configuration of QEMU, the
appropriate read & write methods are selected. This patch also fixes the
zero byte read/write bug & obviates the need to apply a fix for that bug separately.
