cputlb: Fix regression with TCG interpreter (bug 1310324)
...
Commit 0f842f8a24
replaced GETPC_EXT() which
was derived from GETPC() by GETRA_EXT() without fixing cputlb.c. A later
patch replaced GETRA_EXT() by GETRA() in exec/softmmu_template.h which
is included in cputlb.c.
The TCG interpreter failed because the values returned by GETRA() were no
longer explicitly set to 0. The redefinition of GETRA() introduced here
fixes this.
In addition, GETPC_ADJ which is also used in exec/softmmu_template.h is
set to 0. Both changes reduce the compiled code size for cputlb.c by more
than 100 bytes, so the normal TCG without interpreter also profits from
the reduced code size and slightly faster code.

vnc-enc-tight: Fix divide-by-zero in tight_detect_smooth_image{16,24,32}
...
Spotted by Coverity:
(1) Event assignment: Assigning: "pixels" = "0".
(2) Event cond_true: Condition "y < h", taking true branch
(3) Event cond_false: Condition "x < w", taking false branch
(4) Event loop_end: Reached end of loop
(5) Event divide_by_zero: In expression "(stats[0] + stats[1]) * 100U / pixels",
division by expression "pixels" which may be zero has undefined behavior.

vnc: refuse to set a password with VNC_AUTH_NONE
...
Current code silently changes the authentication settings
in case you try to set a password without password authentication
turned on. This is bad. Return an error instead.
If we want allow changing auth settings at runtime this should
be done explicitly using a separate monitor command, not as
side effect of set_passwd.

usb: add usb_pick_speed
...
We can pick the usb port speed in generic code, by looking at the port
and device speed masks and looking for the fastest match. So add a
function to do exactly that, and drop the speed setting code from
usb_desc_attach as it isn't needed any more.
This way we can set the device speed before calling port->ops->attach,
which fixes some xhci hotplug issues.

Extend compatibility test function to also figure whenever usb3
devices can be supported on ehci. Tweak ep0 maxpacketsize field
due to usb2 <-> usb3 difference.
