usb: Move short-not-ok handling to the core

After a short-not-ok packet ending short, we should not advance the queue.
Move enforcing this to the core, rather then handling it in the hcd code.

This may result in the queue now actually containing multiple input packets...

usb: Add USB_RET_ADD_TO_QUEUE packet result code

This can be used by usb-device code which wishes to process an entire endpoint
queue at once, to do this the usb-device code returns USB_RET_ADD_TO_QUEUE
from its handle_data class method and defines a flush_ep_queue class method...

Rename target_phys_addr_t to hwaddr

target_phys_addr_t is unwieldly, violates the C standard (_t suffixes are
reserved) and its purpose doesn't match the name (most target_phys_addr_t
addresses are not target specific). Replace it with a finger-friendly,...

usb: unique packet ids

This patch adds IDs to usb packets. Those IDs are (a) supposed to be
unique for the lifecycle of a packet (from packet setup until the packet
is either completed or canceled) and (b) stable across migration.

uhci, ohci, ehci and xhci use the guest physical address of the transfer...

usb-ohci: Use universal DMA helper functions

The OHCI device emulation can provide both PCI and SysBus OHCI
implementations. Because of this, it was not previously converted to
use the PCI DMA helper functions.

This patch converts it to use the new universal DMA helper functions....

usb: the big rename

Reorganize usb source files. Create a new hw/usb/ directory and move
all usb source code to that place. Also make filenames a bit more
descriptive. Host adapters are prefixed with "hch-" now, usb device
emulations are prefixed with "dev-". Fixup paths Makefile and include...

usb: zap hw/ush-{ohic,uhci}.h + init wrappers

Remove the uhci and ohci init wrappers, which all wrapped a
pci_create_simple() one-liner. Switch callsites to call
pci_create_simple directly. Remove the header files where
the wrappers where declared.

usb-ohci: DMA writeback bug fixes

This patch fixes two bugs in the OHCI device where the device writes
back data to system memory that should be exclusively under the
control of the guest side driver.

In OHCI specification Section 5.2.7, it mentioned "In all cases, Host...
