xhci needs this for USB_REQ_SET_ADDRESS due to the way

  ehci: switch to new-style memory ops

Also register different memory regions for capabilities,
operational registers and port status registers.  Create
separate tracepoints for operational regs and port status
regs.  Ditch a bunch of sanity checks because the memory
core will do this for us now.

Offloading the byte, word and dword access handling to the
memory core also has the side effect of fixing ehci register
access on bigendian hosts.

  ehci: Fix interrupts stopping when Interrupt Threshold Control is 8

If Interrupt Threshold Control is 8 or a multiple of 8, then
s->usbsts_frindex can become exactly 0x4000, at which point
(s->usbsts_frindex > s->frindex) will never become true, as
s->usbsts_frindex will not be lowered / reset in this case.

This patch fixes this.

  ehci: Don't process too much frames in 1 timer tick (v2)

The Linux ehci isoc scheduling code fills the entire schedule ahead of
time minus 80 frames. If we make a large jump in where we are in the
schedule, ie 40 frames, then the scheduler all of a sudden will only have
40 frames left to work in, causing it to fail packet submissions
with error -27 (-EFBIG).

Changes in v2:
-Don't hardcode a maximum number of frames to process in one tick, instead:
 -Process a minimum number of frames to ensure we do eventually catch up
 -Stop (after the minimum number) when the guest has requested an irq

  ehci: Don't set seen to 0 when removing unseen queue-heads

When removing unseen queue-heads from the async queue list, we should not
set the seen flag to 0, as this may cause them to be removed by
ehci_queues_rip_unused() during the next call to ehci_advance_async_state()
if the timer is late or running at a low frequency.

Note:
1) This *may* have caused the instant unlink / relinks described in commit
   9bc3a3a216e2689bfcdd36c3e079333bbdbf3ba0

2) Rather then putting more if-s inside ehci_queues_rip_unused, this patch
   instead introduces a new ehci_queues_rip_unseen function.

3) This patch also makes it save to call ehci_queues_rip_unseen() multiple
   times, which gets used in the folluw up patch titled:
   "ehci: Walk async schedule before and after migration"

  usb-redir: Add an already_in_flight packet-id queue

After a live migration, the usb-hcd will re-queue all packets by
walking over the schedule in the guest memory again, but requests which
were encountered on the migration source before will already be in flight,
so these should *not* be re-send to the usbredir-host.

This patch adds an already in flight packet ud queue, which will be filled by
the source before migration and then moved over to the migration dest, any
async handled packets are then checked against this queue to avoid sending
the same packet to the usbredir-host twice.

  usb-redir: Revert usb-redir part of commit 93bfef4c

Commit 93bfef4c6e4b23caea9d51e1099d06433d8835a4 makes qemu-devices
which report the qemu version string to the guest in some way use a
qemu_get_version function which reports a machine-specific version string.

However usb-redir does not expose the qemu version to the guest, only to
the usbredir-host as part of the initial handshake. This can then be logged
on the usbredir-host side for debugging purposes and is otherwise completely
unused! For debugging purposes it is important to have the real qemu version
in there, rather then the machine-specific version.

  uhci: Don't queue up packets after one with the SPD flag set

Don't queue up packets after a packet with the SPD (short packet detect)
flag set. Since we won't know if the packet will actually be short until it
has completed, and if it is short we should stop the queue.

This fixes a miniature photoframe emulating a USB cdrom with the windows
software for it not working.

  target-sh4: rework exceptions handling

Since commit fd4bab102 PC is restored in case of exception through code
retranslation. While it is clearly the thing to do in case it is not
not known if an helper is going to trigger an exception or not
(e.g. for load/store, FPU, etc.), it just make things slower when the
exception is already known at translation time.

Partially revert this commit and save PC in the TCG code. Set bstate to
BS_BRANCH to not generate TCG exit code. Micro-optimize the sleep
helper. Make all the exception helpers to call raise_exception and mark
it as noreturn.

  gdbstub/sh4: fix build with USE_SOFTFLOAT_STRUCT_TYPES

We have to use different type to access float values when
USE_SOFTFLOAT_STRUCT_TYPES is defined.

Rework SH4 version of cpu_gdb_{read,write}_register() using
a single case, and fixing the coding style. Use ldll_p() and
stfl_p() to access float values.

  tcg-hppa: Fix broken load/store helpers

The CONFIG_TCG_PASS_AREG0 code for calling ld/st helpers
was not respecting the ABI requirement for 64-bit values
being aligned in registers.

Mirror the ARM port in use of helper functions to marshal
arguments into the correct registers.
