Synchronize the CPU state via cpu_sychronize_state() unconditionally
in gdb_set_cpu_pc() rather than only in some of the target ifdef
ladder cases.
We can divide the CPUs into three categories:
* non-KVM targets: no change of behaviour since we will use the
kvm-stub.c no-op function.
* i386 and s390: no change of behaviour since they were already
calling this function
* PPC (in KVM mode): this fixes an error: failing to synchronise
was accidental and probably a bug.
This also paves the way for other targets (specifically ARM) which
can add KVM support in future without having to add another target
specific change to this bit of code.

We can arrive there if transfer descriptors passed to us from the guest

This patch carries a complete rewrite of the usb descriptor parser.
Changes / improvements:
* We are using the USBDescriptor struct instead of hard-coded offsets
now to access descriptor data.
* (debug) printfs are all gone, tracepoints have been added instead.
* We don't try (and fail) to skip over unneeded descriptors. We parse
them all one by one. We keep track of which configuration, interface
and altsetting we are looking at and use this information to figure
which desciptors are in use and which we can ignore.
* On parse errors we clear all endpoint information, which will
disallow any communication with the device, except control endpoint
messages. This makes sure we don't end up with a silly device state
where half of the endpoints got enabled and the other half was left
disabled.
* Some sanity checks have been added.
The new parser is more robust and also leaves complete device
information in the trace log if you enable the ush_host_parse_*
tracepoints.

frindex always is a 14 bits counter, and not a 13 bits one as we were
emulating. There are some subtle hints to this in the spec, first of all
"Table 2-12. FRINDEX - Frame Index Register" says:
"Bit 13:0 Frame Index. The value in this register increments at the end of
each time frame (e.g. micro-frame). Bits [N:3] are used for the Frame List
current index. This means that each location of the frame list is accessed
8 times (frames or micro-frames) before moving to the next index. The
following illustrates values of N based on the value of the Frame List
Size field in the USBCMD register.
USBCMD[Frame List Size] Number Elements N
00b 1024 12
01b 512 11
10b 256 10
11b Reserved"
Notice how the text talks about "Bits [N:3]" are used ..., it does
NOT say that when N == 12 (our case) the counter will wrap from 8191 to 0,
or in otherwords that it is a 13 bits counter (bits 0 - 12).
The other hint is in "Table 2-10. USBSTS USB Status Register Bit Definitions":
"Bit 3 Frame List Rollover - R/WC. The Host Controller sets this bit to a one
when the Frame List Index (see Section 2.3.4) rolls over from its maximum value
to zero. The exact value at which the rollover occurs depends on the frame
list size. For example, if the frame list size (as programmed in the Frame
List Size field of the USBCMD register) is 1024, the Frame Index Register
rolls over every time FRINDEX[13] toggles. Similarly, if the size is 512,
the Host Controller sets this bit to a one every time FRINDEX[12] toggles."
Notice how this text talks about setting bit 3 when bit 13 of frindex toggles
(when there are 1024 entries, so our case), so this indicates that frindex
has a bit 13 making it a 14 bit counter.
Besides these clear hints the real proof is in the pudding. Before this
patch I could not stream data from a USB2 webcam under Windows XP, after
this cam using a USB2 webcam under Windows XP works fine, and no regressions
with other operating systems were seen.

Looks like a cut+paste bug from ehci_detach. When the device itself is
detached from a ehci port (ehci_detach op) we have to clear the
device pointer for the companion port too. When a device gets removed
from a downstream port of a usb hub (ehci_child_detach op) the ehci port
where the usb hub is plugged in is not affected.
