Keep saving display surface parameters at init and using these cached
values instead of getting them when needed. Not sure why this is
needed (maybe due to the interaction with the vga device) but not
doing this broke the Xorg vmware driver at least.

Since 0b57e287, cpu_memory_rw_debug already triggers a TB invalidation.
As it doesn't (and cannot) set is_cpu_write_access=1 but "consumes" the
currently executed TB, the tb_invalidate_phys_page_range call from
patch_instruction didn't work anymore.
Fix this by open-coding the required bits to restore the CPU state from
the current TB position before patching and resume execution on the
patched instruction afterward.

Postpone stopping the dirty log to the point where the command fifo is
configured to allow drivers which don't use the fifo to work too.
(Without this the picture rendered into the vram never got to the

removed a year ago.)

According to the documentation drivers using this device should read
FB_SIZE before enabling the device to know what memory to map. This
would not work if we return 0 before enabled. The docs also mention
reading SVGA_REG_DEPTH but not writing it. (Only SVGA_REG_BITS_PER_PIXEL
can be written but we don't really support that either.)

This follows the logic of host-linux: If a 2.0 device has no ISO
endpoint and no interrupt endpoint with a packet size > 64, we can
attach it also to an 1.1 host controller. In case the redir server does
not report endpoint sizes, play safe and remove the 1.1 compatibility as
well. Moreover, if we detect a conflicting change in the configuration
after the device was already attached, it will be disconnected
immediately.

Older versions (anything but the latest) of Linux usbfs + libusb(x),
will submit larger (bulk) transfers split into multiple 16k submissions,
which means that rather then all tds getting linked into the queue in
one atomic operarion they get linked in a bunch at a time, which could
cause problems if:
1) We scan the queue while libusb is in the middle of submitting a split
bulk transfer
2) While this bulk transfer is pending we migrate to another host.
The problem is that after 2, the new host will rescan the queue and
combine the packets in one large transfer, where as 1) has caused the
original host to see them as 2 transfers. This patch fixes this by stopping
combinging if we detect a 16k transfer with its int_req flag set.
This should not adversely effect performance for other cases as:
1) Linux never sets the interrupt flag on packets other then the last
2) Windows does set the in_req flag on each td, but will submit large
transfers in 20k tds thus never triggering the check

Currently we only do pipelining for output endpoints, since to properly
support short-not-ok semantics we can only have one outstanding input
packet. Since the ehci and uhci controllers have a limited per td packet
size guests will split large input transfers to into multiple packets,
and since we don't pipeline these, this comes with a serious performance
penalty.
This patch adds helper functions to (re-)combine packets which belong to 1
transfer at the guest device-driver level into 1 large transger. This can be
used by (redirection) usb-devices to enable pipelining for input endpoints.
This patch will combine packets together until a transfer terminating packet
is encountered. A terminating packet is a packet which meets one or more of
the following conditions:
1) The packet size is *not* a multiple of the endpoint max packet size
2) The packet does *not* have its short-not-ok flag set
3) The packet has its interrupt-on-complete flag set
The short-not-ok flag of the combined packet is that of the terminating packet.
Multiple combined packets may be submitted to the device, if the combined
packets do not have their short-not-ok flag set, enabling true pipelining.
If a combined packet does have its short-not-ok flag set the queue will
wait with submitting further packets to the device until that packet has
completed.
Once enabled in the usb-redir and ehci code, this improves the speed (MB/s)
of a Linux guest reading from a USB mass storage device by a factor of
1.2 - 1.5.
And the main reason why I started working on this, when reading from a pl2303
USB<->serial converter, it combines the previous 4 packets submitted per
device-driver level read into 1 big read, reducing the number of packets / sec
by a factor 4, and it allows to have multiple reads outstanding. This allows
for much better latency tolerance without the pl2303's internal buffer
overflowing (which was happening at 115200 bps, without serial flow control).

My recent uhci cleanup series has introduced a regression, where
qemu sometimes crashes on a device disconnect. The problem is that
the uhci code never checked for a device not / no longer existing, instead
it was relying on usb_handle_packet accepting a NULL device.
But since we now pass usb_handle_packet q->ep->dev, rather then just
a local dev variable, we crash as q->ep == NULL due to the device no longer
existing.
This patch fixes this. Note that this patch also improves over
the old behavior were we would:
1) create a queue for the device
2) create an async for the packet
3) have usb_handle_packet fail
4) destroy the async
5) wait for the queue to be idle for 32 frames
6) destroy the queue
Which was rather sub-optimal.

vga text mode emulation fails to update both correctly. Depending on

keep track of full screen redraws needed in VGACommonState fields.
