uhci: Fix 1 ms delay in interrupt reporting to the guest

Re-arrange how we process frames / increase frnum / report pending interrupts,
to avoid a 1 ms delay in interrupt reporting to the guest. This increases
the packet throughput for cases where the guest submits a single packet,...

uhci: Limit amount of frames processed in one go

Before this patch uhci would process an unlimited amount of frames when
behind on schedule, by setting the timer to a time already past, causing the
timer subsys to immediately recall the frame_timer function gain....

uhci: Maximize how many frames we catch up when behind

If somehow we've gotten behind a lot, simply skip ahead, like the ehci code
does.

hid: Change idle handling to use a timer

This leads to cleaner code in usb-hid, and removes up to a 1000 calls / sec to
qemu_get_clock_ns(vm_clock) if idle-time is set to its default value of 0.

usb: Fix usb_ep_find_packet_by_id

usb_ep_find_packet_by_id mistakenly only checks the first packet and if that
is not a match, keeps trying the first packet! This patch fixes this.

usb: Add an usb_device_ep_stopped USBDevice method

Some usb devices (host or network redirection) can benefit from knowing when
the guest stops using an endpoint. Redirection may involve submitting packets
independently from the guest (in combination with a fifo buffer between the...

ehci: Don't call commit_irq after raising PCD

ehci_raise_irq(s, USBSTS_PCD), gets applied immediately so there is no need
to call commit_irq after it.
