Trace usb port operations (attach, detach, reset),
drop a few obsolete DPRINTF's.
No change in behavior.

Add functions to get and set the current state of the state machine,
add tracepoints there to trace state transitions. Add support for
traceing the queue heads and transfer descriptors as we look at them.
Drop a few DPRINTFs and all DPRINTF_ST lines, they are obsolete now.
No change in behavior.

This patch starts adding trace support to ehci. It traces
updates of the status register (USBSTS), mmio access and
controller reset.
It also adds functions to set and clear status register bits
and puts them in use everywhere.
Some DPRINTF's are dropped in favor of the new tracepoints.
No change in behavior.

BM_STATUS_INT is automatically set during ide_set_irq(), there's no reason to
set it manually in addition.
There is even one case where the interrupt status bit was set, but no IRQ was
raised. This is when the PRD table was reached but there is more data to
transfer. The correct behaviour for this case is not to set BM_STATUS_INT.

This patch adds a dummy legacy ISA device whose responsibility is to
deploy sgabios, an option rom for a serial graphics adapter.
The proposal is that this device is always-on when -nographics,
but can otherwise be enable in any setup when -device sga is used.

The multiboot info struct's 'boot_device' field has 'part1' set to 0x01, which
maps to the second primary partition. To specify the first primary partition,
'part1' should be set to 0x00, since partition numbers start from zero
according to the multiboot spec.

Commit 353ac78d495ef976242abd868f68d78420861c2c moved the files
without fixing the include paths. It used a modified CFLAGS
to add hw to the include search path, but this breaks builds
where the user wants to set special CFLAGS. Long include paths
also increase compilation time.
Therefore this patch removes the special CFLAGS for virtio
and fixes the include statements by using relative include paths.
v2: Remove special CFLAGS.
v3: Update needed for latest QEMU.

virtio-serial-bus needs to treat "virtconsole" devices specially. It
uses VirtIOSerialPort member is_console to recognize them. It gets
its value via property initialization. Cute hack, except it lets
users mess with it: "-device virtconsole,is_console=0" isn't plugged
into port 0 as it should.
Move the flag to VirtIOSerialPortInfo. Keep the property for backward
compatibility; its value has no effect.

Instead of calling flush_queued_data when unthrottling, schedule
a bh. That way we can return immediately to the caller, and the
flush uses the same call path as a have_data for callbackee.
No migration change is required because bh are called from vm_stop.

The SCSI spec has a quite detailed list of sense codes available.
It even mandates the use of specific ones for some failure cases.
The current implementation just has one type of generic error
which is actually a violation of the spec in certain cases.
This patch introduces various predefined sense codes to have the
sense code reporting more in line with the spec.
On top of Hannes's patch I fixed the reply to REQUEST SENSE commands
with DESC=0 and a small (<18) length.
